I have an os 91 surpass II that was just in a crash however it is not in to bad a shape..it ripped the throttle lever off..just broke the lever that is put in with a screw and then it also ripped off the muffler from the cylinder head.. i am assuming i just need to buy the cylinder head and that lever..(it may get worse as we look at it further but for now that appears to be the only damage)any way i could get the part numbers on these as i can not tell which i need to repair this am gonna have some help in fixing it..just wanna make sure i order the parts i need also any other parts that would be needed in this repair thanks Kieth

These parts can be ordered through any hobby retailer who sells O.S. Max engines and accessories.

If you can do the repair yourself, the engine doesn't have to come into the service center.
