MAC 67

[James Woody]

I purchased a rigger that came with a MAC 67. I understand they run great but I know nothing about them or this particular engine. Is there a source for parts (piston, rod, sleeve, bearings.) ? I have not pulled the engine to take it apart yet so I don't know if is stock or has been tweaked. Does anyone have any setup suggestions like head clearance, pipe length, nitro percent, etc. ? Thanks for any help/ info.

You can likely get bearings for the Mac 67 through Mike Betke, but new p/l sets are no longer available.
