Any oil or water mixing?
I would get a heat gun and check each cylinder to see if you have any cold ones.jamespmack Thanks this. -

Yep, cyclinder temps on a cold start. Before manifold heat soaks.Mr hanny Thanks this. -
It should be obvious if you have a cold one.jamespmack Thanks this. -

Get the temps from cold. Might have to pull manifold and see which hole, or holes are smoking.

An "inflame major"? Sorry,,my '85 Pete, 400BC, sat for a long time, did what you describe, and it was a stuck aneroid valve.
