say what you want about JQ, this video and the long version of this, is pure GOLD info. Thanks dude!!

For the record, both videos are very vlauable. I watched the whole thing about 2.5 times. Now I just need a recap, so this is just a great summary!

Man... I loved your detailed and cleared explanation in tuning nitro engines!

Oly cow! You just CLEARLY explained an issue id been having for many years in one short video! Thank you!

This video is what every beginner should watch, also a good reminder. Great vid! 💪

Finally a real breakdown on how to tune your R/C Nitro. Thank you!!

I have watched 100s of videos about the setting of carburators. But this one definitely the easiest and the best explanation.

Good job on explaining car tuning. Nice & clear

Greetings from the Philippines- your video is the clearest one ive seen so far, il try this out. Thanks 👍

Every tuning video I’ve seen has nothing on this guy. Great channel, superb.

Great Video!!! I was having issues tuning my X-ray. Now it runs great. Thank you. Worth watching the whole video.

Same here. There is no one else then you JQ that have explain this better. With the combo of explain and show/hear the engines different tune it is so much easier to understand how to do this right. I have finally been able to tune my engines. Big thumbs up for this and thank you for your education in engine tuning :).

I must thank you for the advice and easy to digest explanation. Using your information I am now able to tune my nitro engines perfectly, and most importantly I actually understand what's happening which makes the process easier to replicate and dial in. Thanks so much!

I’ve watched the long video and this video at least five times so refreshing achieving the single stage idle

Very good video JQ as is all your videos. For years I always thought you were supposed to have the double idle we’re it was supposed to drop in like 10 seconds. Anyway great video and I’m going to try your tuning method. Thank you!

I'm new to the whole rc thing and started with a nitro buggy. everybody was talking about you have to understand the engine, how it works etc.. didn't get the engine to work right, but now after months of trying I finally found your video and my whole understanding went from zero to a hundred! it's just so easy to understand now. set the idle with the low speed needle and after that set the high speed needle. thank you!

Really good content! Learned a lot! Thank you!

Great explanation on tuning! Thanks for your time

Thank you for this video. I am new to the racing scene and videos like this help a lot.

Great video JQ!

Brilliant video very informative, cheers Joseph

Cool video and helpful still learning. Love the nitro thats all run Hpi savages

Nice video keeping it simple good idle gap is the secret been watching your very capable

Nice video and a great refresh for myself - you cannot go wrong with these base settings and will apply this in my pan car - I’ll report back with my results…also watched your long video and took appropriate screenshots for reference, to be precise I took 50 screenshots 😊

Well I'll be damned. Went out yesterday and fired up my Reds R5R and this $hit works. Was able to get a non-double idle tuned in without much trouble.

My biggest issue is getting the idle to drop down after coming to a stop. This was a huge help I am getting back into Nitro, not racing because the closest track is over an hour away, but I will be picking up an HPI WR8 Nitro Subaru Impreza to mess around with. If I can get enough people interested I have room for a proper 8th scale track and I will build one

Fantastic video will try that in the morning 👍

Very helpful brother. Thanks for sharing.

Great info. Thanks for doing this video

Thanks for this video, i follow the steps and now my kyosho runs so mucho better in high rpm.

Great video. Sadly most people do not understand this topic. I have an post on fbook offering to help people and im bombarded with people who can't tune thier engine. I'm glad you made this video.

This is awesome, thanks 👍 I did watch your full video on this prior to this video. But this one just gave me more confidence that I was doing the right thing yesterday during the break in process on my Losi 8ight Buggy, my 1st nitro car. That's exactly what I noticed, that as I adjusted my low needle, the rpm went up so I had to adjust the idle needle to lower the rpm. In my case of course I was trying to run as rich as possible to keep the engine lubricated. But I managed to get it to run rich to the point where it was spitting oil from the pipe & yet not stalling. I also made sure to heat up the engine prior to starting it & to maintain the temp while idling. I then let it cool between tanks. Was able to get 3 idle tanks in. Now she's ready for slow figure 8 break in runs. Thanks for these amazing 'how to' videos! 😎👍

I’ve watch many tuning videos and this video made tuning click in my head. Got my tmaxx with a stock carb singing on top with a snappy bottom. Got the same results with my 8ight t.

Very helpful, thanks!

Nice! Really helped me out, and also- what car were you running? I would like to look at getting a second nitro and it sounded and looked amazing!

Hi mate,impressed.keep it going.

Thanks for the info was very helpful

I am gonna try this on my Hobao Hyper 21 engine; I always had problems with fuel buildup during idle, if let the car sit for more than 10s and then floor it, it would start to bog and most of the time just stop running. The manual says a 1mm gap is correct for idle, but I think that this is just break with rich settings now; gonna try 0,5mm next time. Thanks for making these videos!

I have become a pro because of this valuable information bro! Thank you!

Gibson electric guitar D string is exactly .5mm. Works pretty good as a feeler gauge for setting idle speed

WOW ! AWESOME ! Very useful video ! Thanks

I just finished the long video for the third time and came here just to be safe, only to see what I had just watched and taken many notes of. Still, watch the long video people! It’s definitely worth it! 🤟

Damn I needed this… I was happy as long as it wasn’t shutting off when I took off or hit the brakes and now I have it close to what I need for a little race around the yard 🏁🏎️😊👍

Wow you make it so easy .

Top video ..ill b looking out for more .many thanks. Mark. Rs4 nitro owner.

Best video on UKposts thanks 🙏 Tony blue mountains Australia 🇦🇺

This has to be the easiest way tuning a rc race engine, I really learned a lot I’m literally a Rookie at this and I just purchased the Serpent SRX8 RTR so your video so far is simple and to the point , I’ll be using your video for reference for tuning my engine. Great instructional video 👍👍👍👍👍 I’ll pass the word around vato

AWESOME video sir ,thank's.

my god thank you i am new to nitros and this is the best guide vido i have found and helped me tune my nitro

Perfect video 💯💯💯

TUNED MY BLOK 21BM WITH 05 GAP THIS WAY, ROCKS

Really nice video. Suggestio talk about glow plugs hot and cold ones and for next videos. How to you break in your engines and how to identify problems on nitro engines.

The most informatice video for 10 years 👍👍🏁

Pretty good work

good tutorial...but when are you going to bring back the JQ rtr buggy?

This is a great video. Thanks

Gold! Thank you

What you are doing is called an idle drop in the motorcycle word. Just the low end portion. Great videos

Going to tune my eight t rtr tonight with this.

Dammit, I watched the full older video. And I'm American. But mostly Italian, English, German and French. Great videos.

This is the way. I got this from Ron Paris a long time ago. it's the single source of truth for nitro setting.

hello i have just recently fitted a new engine and run it in, so when i have adjusted high speed needle clockwise and it runs great full throttle and driving but once i leave idling and then go to take off it bogs down and sometimes stalls, so with that in mind what do you suggest i need to adjust to make it idle and not stall on take off. thank you

I came here to see if the tuning process is any different than dirtbikes. Dirtbikes with high compression pistons and race carbs are tuned in a similar fashion especially when you use 110 octane vp race fuel. Thanks for the info just bought my boy a nitro today.

Is there like for example a iddle gap which is useable for different egines? Like for example my reedy v121. I orderd some precision feeler, and i would mark like you 0.45 0.50 0.55. Great work, and much love from Germany 🙌

Hi, watched the full video and am commenting here for the algo, gl with YT JQ.

Cheers mate thks for sharing.

Thanks 👍

What do you think about the t- works back plate for o.s.? Im running ultimate engine.

I love this video, but I only have 2 screws: idle and maybe a high speed screw. I'm very new to the hobby

Great video

Hi bro JQ👋👋👋...can white edition car using some Black Edition parts??..Its fit or not?..

People over complicate nitro tuning.. I agree on the "Factory settings" not being the best method comment .. I prefer sound, temperature and feel..! I'm digging the JQ UKposts channel!! Dude knows his stuff and it make sense when he is explaining something..

Are RC airplane nitro motors similar tuning or completely different?

I have a vrx 1/10 scale nitro buggy. Can you help me if what is the factory default settings of my rc? Thank you

Subscribed!

There's some crazy custom one off experimental stuff going on with that test car right there. Any of that going into the new car? And will it be the Brown edition? aka the Shit lol

i have watched this now 3 times and the long 1hr video. can i use all of the tips and settnings on my onroad cars?

Can you do a video on how to tune the MSN

A lot of people don't have that gauge i been using a business card Gap it measures about the same it puts you in the window

I have a problem with my new sh engine I’ve broken it in fine I’ve reached optimal top end but I can’t get the lsn set right I e got great accelerations but I keep getting a two stage idle when I get a single stage idle it does fine but if I blip the throttle it loads up and flames out if I set it to stay running I get a double stage idle

Hi and great video. I watched the whole vid by the way. I was curious if I could ask for your assistance in tuning my engine. It is an Aplha dragon 21. When I rev it and the rpm drops, the idle goes up for approx 3-5 seconds before coming down. What to do?

Question i know that we need to always tune engine for that day but my question is before starting engine do you richen the low and high speed needles before starting engine and set to factory settings or just fat enough to here it and then tune from there, great vids i feel like a pro now on tuning by watching your videos ive been on and off for 11 years and lots of tuning videos you rock man.

Would I not be able to install an A/F ratio meter in my engine?

I have an old engine With only 2 needles. An Idle needle and for speed. Any tips for That ?

Awesome video on tuning!!! But i want to know about that car???? 🤔

Take the air filter off the carb and look inside and see the gap and set it. Put the air filter back on and start tuning the carb

Hallo from Greece. An old engine i repaired thunder tiger 21 pro, i tuned and it works. I only have one problem. When the car runs top speed, throttle is full , and i close it, after 5-6 seconds a while the idle drops and goes off. If I move it the car endlessly, the idling does not turn off, works fine. The problem is the idling after form top speed.This engine have only two valves, HSN and the other side, midle valve? . Not have LSN (small screw) ,like the other engines

I know my idle gap is .07mm for my engine. When I start it initially the idle is high. So that means I richen up the low speed need to lower the idle correct? Thx for the informative videos.

Great video. #thewing

Good video!! I’ll have to go watch the full vid. What do you mean 2 stage idle? I’m pretty new with nitro & have watched to many nitro tuning videos. There is to many nitro clowns out there that have been doing nitro for a year & act like there way is the only way, when actually they just copy everyone’s video’s lol. They don’t race or anything run there nitro in there yard, up & down the street, it’s really lame!!! Anyway I really like your channel I have been watching all your vids almost, even older ones, when you built your own cars “the car”!!! Keep up the awesome video’s!! Subbed & liked!👍🏼🍻

Hey there, that looks so damn easy. Is the perfect idle gap is written in the manual?

Ok I have a sh PT21 XT2-P8. It's a very new engine I have in my 1/8 on road. I have run over ten tanks of fuel. I get the engine to idel great. But when I pull the trigger the engine cuts out I have the high speed needle rich and the bottom needle at flush the mid range is set .10 mm in. I just can't get the engine to work properly. Any ideas on what to do????

When your tuning in the video are you giving it full throttle as you adjust the needles?

This video along with the full version has been very helpful

Say my engine seems good it has good power high rpm response is pretty good but when I’m partial throttle and stab it it’s very rich and doesn’t clear right out if I go from idle straight to full throttle it clears out fine

is the idle gap the same on 16% nitro? (0.45-0.55)

Ha what pipe is that it’s like a bronze color never saw one like that constantly polishing mine like the looks of that one

I watched the original video to learn how the carb works and what parts there are. Now I’m here because I want to be able to tune my own car and tell what my car is doing rather than my dad being like “oh it’s running rich, bring it in so I can lean it a little” and I’m like “umm ok. Whatever you say pops”

Does anybody know the idle gap for a dynamite mach 2. .21

Thinking about getting a tekno nitro buggy. If you have time can you do a getting into nitro racing 101 video?
