Hey guys, i have a Kyosho inferno gt and is given me a lot of problems. I can't really run the car , cuz each time that i turn on the engine, it will turn off. I don't know if the problem is the needle or the idle mixture screws, I tried different way fixing the idle mixture screws. Sometime the car stay on, but when I push the throttle it will turn off. I need help please, what do you guys think is wrong with the car.

try a different glow plug

Will the engine stay running with the glow plug ignitor installed?

francsperez

Well, I didn't try that, only like for 15 seconds and it stay on.

Bubblehead

I don't understand, try leaving the ignitor on and see if the engine stays running.

Does your motor still have some pop or pinch to it?

francsperez

I will, but do the real problem is when i push the throttle the engine shuts down, do you think it is because the glow plug?

The glow plug may be too cold. When you open the throttle, fresh fuel will enter the combustion chamber and if the plug is too cold it will cause the engine to flame out.

Leave the glow plug driver attached to the engine and if you can rev the engine with it hooked up then you need a hotter glow plug.

It's just a troubleshooting tool, an old glow plug will not burn as hot as a new plug the ignitor will keep the glow plug hot.

Ok guys thanks, i will buy a new glow plug, also i will leave the glow plug ignitor attached to the engine.

Is there a lot of smoke and fuel coming out of the exhaust pipe?

If so, turn the top needle 1/4 clockwise and repeat until it doesnt stall.

I've written many rookie tuning tips in the rookie section..

all start with.. 1mm idle gap.

If you want more info, just ask.

francsperez......

All of these previous tips look good but as I was rereading your description, I thought I would ask if you've checked your 'servo reverse'.....make sure that 'adding throttle' is not actually 'closing' the carb instead.

Good luck....

Check out the tuning bible, it should give ya a good place to start. But sounds like it could be a glow plug or just way too rich. Always remember to set your air gap at 1mm before ya start tuning.

I always recommend a Hot plug for new nitro owners because a hot plug will tolerate a rich mixture much better than a medium or cold plug. With a hot plug the engine is more easily started and the car will accept throttle without flaming out (unless it is super rich). This allows the car to be driven and then the carburetor can be fine tuned.

Hey guys, thanks for the help. I left the glow plug ignitor attached to the engine, and it stay on. Also was running the car for a long time. But im sure that i need a hotter glow plug. Sure that was the problem!!!!
