Re: ignition questions?
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.

Re: ignition questions?
I have seen lots of folks miss that wiring bit, so it is worth checking.
Pour the ATF slow while keeping it running and be warned it 'will' give
off one massive white smoke cloud.

Re: ignition questions?
yeah it sure did dump out some white smoke. even more smoke than the 2
stokes i'm used to working on. but i still cant get the timing above 7
degrees with out pinging. are there different vacume advances i can bolt to
the distributer? it seems to me i need more advance on cold starts and less
timing advance around 2500 rpm's when i am coming up a hill. i'm just not
sure how to go about doing it.
