318 Poly Vibration

After the 30 min I also drove it around to see if it would clear up. I also pinched the fuel line before the carb to run it dry, thinking maybe something was stuck in the needle/seat because it smelled bad.

Those plugs are literally brand new white on one side, black on the other. Never seen that.

I agree I need to get timing right first.

I'll start over. From my recollection I turned it clockwise and the timing advanced from 10 AFTER to 10 BEFORE, but I must be wrong.

I'm also struggling with identifying cause and effect, or lack of. The only thing I did before working on interior was to disconnect the battery so the interior light wouldn't burn the lens up.

Same thing happened when the battery died, in my first post, ran great, shut off, battery dead, replaced, ran like crap.

Will try again.
