Re: #1 plug question
My distributor body to rotor shows .025 on 3 cylinders, with .045 on number one. It does not seem to make a real difference.
I think you need to check how much gap you have between the distributor body and rotor for each cylinder. If anything is over 0.50, I would suspect that maybe the problem.
You can check the gap between the dist body and rotor by simple turning the engine over with a crank and using a feeler gauge.
My other concern if your gaps are within tolerance, would be either compression on that cylinder, or, possibly a valve hanging up.
