Thank you!
I honestly don’t know the condition of the engine prior to this, I got it from an unfortunate circumstance. I can check the distributor cap tomorrow and see how it is.
I do want to mention I did the compression test on a cold engine, no way I could do it after warming it without being burnt. I already swapped the plugs with NGK UR5s and have some heat shield for them on the way. If that still melts, I’ll get the ceramic ones. I can pull them and go ahead and increase the gap like you suggested though.
What’s a typical width of the carburetor gasket? Mine is quite thick. Any method to test leakage past them? I tried the spraying carb cleaner on them and listening for rpm increase.
Thanks for that link, I’ll go ahead and order it and give it a shot.
