If the engine will idle, what happens if you slowly increase the revs...slowly...does the engine seem to load up and finally stop, usually then pushing unburnt gas out the carb...aka Puke...
With cylinder pressures in the 190's, the vales are closing ok, pushrods are not too long....but !!!!
I have seen a bad lifter pump up and hold a valve open, then bleed down and compression test out ok...
If it was me, drop the pipes at end of headers or manifolds...if still no good, I would look at a bad lifter...even new stuff can be bad...
Question...is this a roller cam engine or flat lifter?
keep smilin mate...we will get it going...   |
If I slowly raise the idle it revs up, but you can tell it's just not right.
You have a great idea on the lifters.
