REFLECTOR: Engine troubles

[Geoff Gerhardt]

Thanks for all the input.  Turns out there's a local guy here that rebuilds
cylinders (most of the local A&P's use him, apparently).  I talked to him
on the phone.  I'm going to pull the cylinders off and bring them to him to
inspect.  Hopefully it won't be too long to get them rebuilt.
 Unfortunately, I have to head to China tomorrow, so it'll have to wait
awhile yet...
