hi dave-
after getting kermit outfitted with the new engine/trans., i went out for a
ride today- real nice, but the torque just wasn't there [STILL!] so i came
back home and grabbed the compression guage. crap!!! 120lbs., left cyl., 150
rt.cyl........
question- i lubed the cyl. walls with a liberal dose of stp engine oil
treatment before sliding them over the pistons. is it possible that this
sticky stuff has prevented the rings from sealing? i was gonna assemble them
dry [figuring the nikisil is hard stuff & could take it] but d. richardson
reccommended against it. i did lap the valves, so this is the only thing i
can think of. if so, i guess i gotta tear it down again @#$!!%&(%!! and hone
[?] the cyls.???
any advice is needed& wanted, with thanks!!!!!
andy
