Thanks to several of you who replied. Your suspicions were correct: the motor
had been driven hard (and hot). Piston skirts scored, cam had worn grooves,
cracked cylinder heads, and a baked in grime inside that smelled pretty bad.
Tearing the machine down and cleaning it up has been a blast. I've sent the
case to be cleaned, and am shopping for parts now. I'm a little shocked at how
much these air cooled suckers cost to rebuild...new heads, ~400 ea., cam ~180,
piston/cylinder set ~425....add up all the big an little stuff and I'm looking
at $2K easy. And I thought that since there were so many of these things alive
and kicking, that parts should be fairly common (and cheap).
Makes me wonder (here's a kook idea)...has anyone ever done a hybrid
conversion? If the bug air cooled engine were significantly cheaper to maintain
and has better mileage/emmissions...then it might be a cool idea to build an
aircooled hybrid. Bug motor powering an electic motor and battery bank.
Undoubtedly more expensive than simply rebuilding my motor...any thoughts out
there?
