Yes, I know it's a late model cast crank motor.
Surprise, surprise! Pistons have "30" stamped on them, so it's been rebuilt at least once.
#2 cylinder also has rust on the outer wall. It looks like #2 and #3 had standing water in them for a time, but not the end of the world. I'm soaking now and will bang on the pistons tomorrow to see if I can coax the motor to turn.
Then I might get 250 for it.
Overheating and running out of oil have been scratched off the list of problems.
Thanks for the help and happy motoring,
David
