Sounds good on the high end. Richen up the low end adjust you idle gap a bit. Nice vid

If you get it to idle, leave the glow plug heater on it for 10-20 seconds after it fires this warms up the combustion chamber to the point the engine can properly diesel. Easy on the throttle at first and let the engine warm up, it might take 1/4 tank of fuel for it to get to that point, when the engine is hot, refuel and have fun. If it is pissing fuel out the pipe at idle, the low speed is too rich, lean it out 1/4 turn at a time. (Clockwise on low speed) as soon as you find that soft spot, don’t touch it again. At mid-full throttle, if it bogs, (with exhaust smoke) it is too rich. Lean it out 1/2 turn at a time. (Clockwise on high speed) If it bogs (no exhaust smoke) it is too lean. Richen the mixture (counterclockwise on high speed) This is the screw that you will have to adjust in accordance to temperature. Hot outside = tune lean Cold outside = tune rich. If you want to F around with your nitro car in the snow, the car most certainly will not start if it is too cold outside. Example: 20F outside, you’ll be best off starting it inside a place that is 40F and above. Let it warm up, and adjust accordingly. Idle screw: Clockwise = higher idle, counterclockwise = lower idle. Adjust accordingly, when you find the right idle RPM, leave it alone. That’s all there is to it. I will add, if you don’t have a good glow plug heater, you will suffer. If you are serious about running nitro cars today, buy a starter box, and a hardwired heater that can plug into it. Screw pull starts, and Roto-Starts. If you buy a starter box, 90% of your problems will disappear. Of course all of this is subject to change depending on what fuel you run, pick a brand/mixture, and stay with it. If you buy another fuel, you’ll most likely have to re-tune the carb again. If you burn VP, stay with VP. If you burn Traxxas, stay with Traxxas. If you burn Sidewinder, stay with Sidewinder. KEEP YOUR RATIOS. If the fuel is (brand) with a mixture of (what you are currently running) buy the same fuel over and over until you are forced to find an alternative. Nuff said, TL/DR, buy a starter box for your nitro rc cars, and get a glow plug heater that can plug into it, adjust the carb accordingly, and burn the same fuel.

You did not show the third screw for tuning.

Where did you get you igniter at

you dont need all that pipe that can cause issues and remove the pump no need for it

How do you know if the engine is flooded, You did not explain how.

Do the engine use oil?

Sounded like it was lean bogging off idle on the box

How do you no if the engine is flooded, Explain, Bad instructions.
