OS-40 MAX-H
« on: October 31, 2014, 04:49:33 PM »
Flying buddy has one, tried to get it running for him.  No compression.  Took it apart thinking ring might be stuck, but it wasn't.  Probably needs P&L and ring. Its old, history unknown, but lower end seems to be in good shape.  Are parts still available ?   Anyone still rebuilding these ?

I have many parts for them, and a couple of new ones, plus maybe a few used ones, I will have to see what is here and I can let you know what I have
