Well what a fun day! Took the toon out on the water with the wife and her friends. Motor ran exactly the same as it did before. So again I cranked all the air bleed mixture screws all the way in to full rich so I could at least keep the motor running while trying to idle around in some spots. Near the end of the day just cruising around 4k rpm motor quits. Restart, hard to keep running, limp into the luckily very close boat landing. Come home and do a compression test, 20psi on cylinder 2, all the rest are 120+. Pull the head and sure nuff, scorched cylinder. So that was fun.
I am curious now. Anyone ever pop the rod cap off threw the intake, pull and replace a piston, and overbore/hone the cylinder with the motor together yet?
