I think I will go the new crankcase route. $20 (+ shipping) + paying local hobby shop $10 to replace = LESS THAN BUYING NEW ENGINE
I do not want to attempt taking the engine apart myself, too many small parts I will lose and I'd never get it together again
Thank you all so much for quick responses.

I don't think repair is an option, in terms of being worth doing or economics. A new crankcase is $20.
