fuel problems.

[rbuchanan65]

I am having trouble with using to much fuel. with it idling you can see the fuel coming out of the exaust. but it is not spuddering or cutting off. and when I do cut it off it fills the exaust. Is this normal? If i adjust the fuel/air mixture it runs like crap..

How are you shutting it off?

 

[rbuchanan65]

Finger over exaust. That is how I was told to do it.

That floods it. The best way to stop an engine is to touch the flywheel with something. I normally use the handle on my tuning screwdriver.

ok I'll try that. but I have another question that i have seen alot on this forum.. What is the purpose of making sure the piston is all the way down while cooling?

 

[aj200415]

when the engine is running, the temps increase obviously. When it cools, the sleeve shrinks around the piston and the piston can get stuck, or siezed, into the sleeve. When you try to start your engine again, it wont budge, or worse, it will break piston/ conrod.

Arnt you supposed to pinch off the fuel and let the engine burn itself out of gas???

That is how I do it...it insures the fule in the engine get burnt.....right???

yes, but it temperarly runs your engine lean, and some dont like the idea of it.

Last result pinching or plugging the stinger. You'll tend to foul more plugs using those methods. I usually stick my thumb in the flywheel or the tip of my shoe.
