'86 excel 340 crazy rich, whats wrong?
Ive been trouble shooting on my excel.
It will start first pull...will idle fine for a bit and then the idle will slowly lower and die. You can keep it running by giving it throttle. It can rev up but does bog a little if you increase the throttle quickly.
I thought it was getting too much oil, because it does smoke a lot. I unhooked the 2 oil lines that go to the intake (did not remove the oil line to the oil pump) and ran mixed gas. still smoked really bad and did not run any different.
The plugs are certainly getting fouled. Now I am wondering if the carb is super rich.
I don't use the "starter" fuel enricher/choke when I start it.
If I give it choke when it is running the rpms drop.
since it has to have some throttle to stay running and dies off if you open the choke, it would seem that it gets too much fuel and not enough air.
I have checked the bowl float level and checked that the inlet needle closes. I cant find any info on proper float level, but using common sense I did adjust it some...which made no difference.
Other than the float level...and the 1 needle I can adjust, I don't see any way for the carb to be made to run leaner. It is not just running rich like it bogs, it runs so rich that you couldn't really drive it right now.
