So, was handed a 660 clone that "won't run". Pulled the cord...OK, tried to pull the cord, lol pulled muffler...o boy...explains that
Go to pull the cylinder...stuck. hmm...had to pry it loose.
Turns out: piston cage blew, roller bearing wound up, in several pieces, into the combustion chamber, ouch...
Upon teardown I find a spot where one of the oiler bolts pushed into the crankcase, hm...
FW bearing would barely move...hmm.
Gonna need a few parts...
The owner wants it fixed...ok
