RE: Piston and liner fit and performance
Maybe this special engine was complimented by a good pilot? could that be the reason for better times? maybe the engine is running more RPM in the air because the pilot flies smoother than the rest of you guys? And being that the engine is badly carboned, that just tells me that this guy pushes the engine to the limit by running it leaner than you guys.
What were your times compared to this 76 second run???
