Dave,
Truly, I hope it all comes together for you, both the engine and the ability to run it. Best of luck!

Kurt - I've seen Daves mc10 run on numerous occasions and it was fast for sure, hopefully he can get it right again. Just think if he had stroked it on the initial build.
Dave - hope you can make Avon, we haven't seen you in awhile!!

Dave, so what IS the displacement on your "tiny" Mc10? Which crank is in there? There's something about the '10 port layout that allows them to really scream, whether they have the original or the factory stroker crank. I outran many, many 30's and 40's with my 5.8" Mc10, including my own modified '40. Of course, it had the same porting as Horstman did on the factory Go Kart team engines. There's something appealing about the appearance of the '10. Jack Canady has what I believe he told me is a '92 with Mc10 flywheel and shrouds. Lots of conversion work, but what a tidy little piece.

If you put a thin Dremel cutoff wheel in the high speed drill press, lay the thick ring on the drill press table and adjust the table height so you cut a groove right around the middle of the face of the ring, leaving two "rails". You reduce the wall drag by a BUNCH. The groove also retains oil. You just get the table at eye level and rotate the ring gently against the cutoff wheel by hand. I have prepared PP AH82 rings this way for Hank Rotroff. He calls them "Johnson rings". They have run very well for Hank in the past. Ted

Dave, if you doo "The groove thang", the rings don't even get hot enough to worry about. Just don't groove the end of your finger! ted
