Disappointed,

Last Nov. I was involved in an 833 imput leak, that went on and on, I mentioned the snap ring issue 2nd post cuz of experience.
I also was going into great detail about how rocker shaft oiling occurred in two "squirts" - every two (2) crankshaft rotations, - for the second time in a coupla weeks.
Some still don't get it, I re-read the posts, thinking they had somehow changed to a different language, but no, English U.S.
Then I ran into this old quote from over a decade ago on another site I frequent.

It's so true today as it was decades ago .
(Replace "carb" with whatever)

Good luck .
Sometimes the actual solution is too complicated to implement or hard to accept! Hope becomes the next strategy.
