If it smells like a fuel factory out the tailpipes, it's not close...
I wouldn't mess with anything else until you know where the idle/initial timing is set.
If you reach in at idle and twist the distributor clockwise and it picks up RPM, it want the timing you just twisted in.
really? any time you can turn the dist.and the rpm increases your engine wants more timing?
WHAT!!!
The RPM will ALWAYS increase when the timing is advanced.
Id bet you need to rejet the primary jets down a couple of sizes. Thoss those Chumpion plugs are good for plugging the holes to keep the cylinders sealed. Put some real spark plugs in it.. .
