Oh, wait, you are asking about converting a glow engine to gas. Have a look at Kens site at:
www.lambertsrc.com. Even if you don't purchase his services, he specializes in Super Tigre conversions and has pics on his site you might find interesting/informative. I believe he has some videos too.
Be aware that adding a roller bearing to the rod also necessitates changing the crankpin for one made of hardened steel. I am not a big fan of these conversions, even though I own and fly one that works just fine....
