I also love the sound of antique engines Thk u for da showing 👍💯

If you put a twist in the belt that drives the water pump like a figure 8 the pump will run the right direction. It won't harm the belt since the engine won't be running for long periods of time. Hope this helps!!

I wish it came in hundreds of pieces as a kit you build. That would be SO FUN

Thanks for sharing your H75 running, Steam 212” Man. -it sounds really good. Sounds so good, now I want one, even more, haha. Bet it will continue to run better and better as you get some time on it. Later man, -Jon Cook

Soon I will have this engine model, the engine is very beautiful.

A superb model.

Thank you Steam 212 deg - Your video led me to also pick one up. I agree, the water pump is rotating in the wrong direction, so crossing the pulley belt over was an easy fix. I'm not doing that with the radiator fan as I think it will also work well blowing air out through the radiator.

Neat ! The fan blowing forward was common on some tractors and pretty much standard on stationary engines and forklifts. Been a few years since I was around any of the real Holt's so don't remember how their fans were set up. Dang I want one !!

Thanks for all your information, I’ve got it running, by the way, in the future I might have to change an o ring, is it possible for you to guide me on changing one?

its a pusher fan. alot of old tractors and stationary engines had that. if theyre just sitting still they would pull heat away from the engine. i always felt like thats just pushing hot air through the radiator but i don't know lol. they had them for 90 years so they must have a purpose lol

Thank you very much Steam 212, very useful tips especially about the fuel and oil. These kinds of engines should not run on Zippo fuel! They will jam! I used 2stroke Husqvarna alkylate 2% XP Power 2 fuel. Works fine.

I love steel models

So they designed it to run clockwise? The Holt/Cat engine on a Caterpillar Sixty turns counter clockwise as do most (all?) Holt tractors.

This is incredible! I love these little model engines. Did you make the wooden platform it sits on or did that come with the kit? edit: I checked the site and I see it comes on the base. Thanks for the great video!

Thank you but can you tell me how much you paid

can the water pump belt be crossed over to correct the direction of the pump?

Hi, I’m intrigued, do you you just run the engine with no work load?

Be careful using a plastic syringe to fuel your engine. Depending on the type of fuel you use and the plastic material the syringe is made of, the fuel can start to dissolve the syringe and end up in your fuel system. It looked like you had to push the plunger fairly hard which is an indication that the plastic is being effected? The fit and finish on these engines is poor at best. They know the areas that need attention and the ones that don't. Most of the loose tolerances have little effect on the running of these engines with the exception of the governor. It defiantly needs some attention. There is certainly no excuse for the water pump turning the wrong direction. Centrifugal pumps are defiantly not reversible. Still a nice runner. Enjoy your engine. Cheers Willy 7/4/2022 Allot of full scale industrial equipment have reverse air flow through the radiator. I think it's to help prevent dust from plugging up the radiator fins and blowing it all over the engine. Not to relevant with a model engine. In regards to the direction of the water pump turning, you could put a twist in the belt. Have you heard if they fixed this yet? How much time do you have on it? Hows it running now with some time on it? Cheers Willy

Now I'm seeing these on ebay "new", selling to highest bidder. Actions closing anywhere from $550-850 shipped. Anyone know about this? Are these factory problem units or returns?

I want to buy this but I don't trust the quality control. I bought a single cylinder M12 from company X and it had a bad plug and a stripped head bolt. Still cant get it to run. Your water pump runs backwards?

Anyone know the spark plug gap for this engine? Mine seems to be too large. Thanks.

Steam-- How's the little H75 doing these days? Still running OK?

No need to change anything. It is normal for engines to run in a clockwise direction as viewed from the radiator end.

Twist thebelt will change pump rotation.

Where can I buy spark plugs for the engine?

Can you Link to thath engine pleace. How mutch it cost?

You might cross the waterpump belt so it runs in the good direction

Do you recommend 2-stroke petrol or, as the manufacturer writes, petrol 95? I just ordered the 2 cylinder model.

I can see this model engine sitting in a large scale model tug boat.

Excellent ,how much ?

Put a twist in waterpump belt... it will let pump rum other direction.

Kool,,,,, found it

Steam212° Is there a way to contact you i working on Cole's Holt 75 engine i am struggling with .. I also have a traction engine needs some attention had some holes drilled threw steam chest when they over sized the studs blew threw the castings in many spots on the edges i needs some one who possibly could help me repair it with guidance i grate a repairs im just at a cross road dont know what to do.. Thankyou

Can it be used in a rc car?

Put a twist in the water pump belt - then it will go the other way.

Does it run with petrol?

two-stroke petrol in a four-stroke engine???

How big are your hands? Lol those cylinders are only the size of your thumb. 😂what a near little engine. What is the bore size?

I have one of these engines. I am having ignition issues with. I have found when it is first tuned on there is no spark. If I let it set for about a minute with switch on not turning it or anything. Then try it, it has spark and will run. Has anyone else had this problem?

my last name is holt love your engine

Como consigo esse motor para um min caminhão

How much price

Why don't you just flip the pump belt over half way to make the pump go in the right direction? Like on this one: ukposts.info/have/v-deo/bI-mmJmebqBquas.html Also, the radiator doesn't care which way the wind blows through it as long as it moves. Of note, the original Holt caterpillqar engines turned counter clockwise from the flywheel end so the pump is actually a correct design that just needs the rotation reversed or the exit tube moved to work on a clockwise rotating engine. I happen to like the clockwise rotation as it is very easy to start by hand.

The reason the fan and water pump are moving backwards ,,,is that,,,,,, your turning it backwards,,, You said it was a steam engine ,,,DA !!!!

Nice!But,i think,very expensive,for the Money you can buy a good used Car 😏

Ccw bud...

Too bad it's "Made in China"!

Beautiful china 🇨🇳 copy 👍

Why does everybody mess around with the throttle lever, but NOBODY seems to ever give the flywheel a bit of resistance to see if the governor picks up???????
