Hi A.M.
I have a 48 Surpass. It really has very little time on it and was an awesome engine. The other day it quit running while flying and once on the ground I found it had zero compression. I took it apart and found it had dropped the intake valve. The keeper failed and now the valve is bent. Everything else looks fine.
Now my question. I went on the tower website looking for a valve/keeper/spring and it seems these parts are unavialable. Are you no longer supporting this engine with parts. Or will the valves/springs/keepers from the 52 work.
Thanks for your time
Brian
