What kind of carb are you running?

Do you have the correct gas filter in it and is it in right side up?

Which vacuum advance are you running?

i am running a weber carb with the vacume advance taken off of the base of
ther carb.so i would assume this is manifold vacume. as far as i know the
vacume advance is stock. i am running a one line fuel filter with a pressure
regulator. i dont know if stock timing would apply to my jeep because it is
a 86 with a r.v. cam and all the computer and emmision stuff taken off.
thanks carmine

Do you physically have the ignition module connected directly to the
distributor or does it still go through the computer?

The reason I ask is if the computer is still a physical presence, then
it has gone into limp home mode which messes with the timing advance big
time.

You can tell by looking at the ignition module, waaayyy down under the
washer bottle. Check the purple wire coming out of the module. If it
isn't jumpered to a new wire, you have issues right there. Stock, the
purple wire goes nowhere, it stops at the first plug.

If you remove any emissions stuff, the ignition has to be rewired to
work right. It is easy, I always add two new wires rather than mess
inside the harness. http://home.sprynet.com/~dale02/ignmods.htm

One other thing is carbon build up. That RV cam and running low RPM are
really bad for carbon build up. This will cause pinging.

I run a pint of ATF slowly down the throat of the carb while keeping it
running with my hand on the throttle. It cleans the carbon out great.
Some folks use a pint of water to do this and say it works well too.
