Ease up RRR, He’s verified that the timing chain hasn’t jumped, he’s tried shooting starting fluid into the carburetor, he’s tested for spark, he’s done about everything that’s been asked on these last six pages. For the record, I don’t think the 60 psi per cylinder is correct either, but cut him some slack. The car went from running fine to not running overnight. He’s changed out a crap ton of parts, but the end result is still the same. The engine does not run and nobody’s been able to help him figure out why. I think, like suggested above, he needs to have another set of eyes look at this car to figure out what’s going on.
