Wow, fuel in the PNW really screws with carbs over the winter. These were spotless last summer when I started this thread.

That was for my dead cylinder, the others are bad but still have some holes clear! I'm getting a set of gaskets/O-rings coming for all of them.
Cold kicking compression: #1/150psi, #2/150psi, #3/145psi, #4/142psi
A little low compared to the book's hot spec, but I think it's acceptable yes? 23,000miles.
Starter issue: Idler has 1/8-3/6" lateral play on the shaft. Starter when turning by hand is very gravely. I'll take it apart and see if a rebuild kit will work or if I need to source another.
Valve Lash:
#1 i-.15mm, e-.22mm
#2 i-.13mm, e-.10mm
#3 i-.05mm, e-.18mm
#4 i-.10mm, e-.20mm
So those are all over the place. Pulled the cams and got the shims out. Starting a file to determine which all I need. Not a difficult job, just annoying I guess. Technically only 1E, 3I, and 4E are out of the 0.08mm-0.18mm spec.
And I'm ordering new throttle cables. Can't seem to find a good source for the carb holder clamps though. Maybe just hose clamps? I'm hoping that's all the leak was, that maybe It wasn't so much a vacuum leak, but rather fuel delivery? The engine definitely changed with some spray around the holders though. :O(
