I hate to disapoint you guys but we are doing nothing on the carb. We are running stock tubes (what ever came from Rotax) and needles (K27). WE have gone to a bit larger pilots, 35/35 and other than that, I go off the Max Jet software for main and needle postion with no compensation. Gearing is 13/77 or 76 depending on which way we go. The engine is as purchased from SSC.
I do have one carb with the ICC style slide using stock internals but have not tried it at IMI yet.
The reason Greg is fast is because he has almost 9 years of experience running around IMI including class championship trophies and has traveled to over 20 different tracks around the country. He works at a kart track (Action Karting) and drives a kart almost every day. He also has had the good fortune to work with one of the best driver coachs around for more than two years, the same man who worked with Scott and Alex Speed when they were young.
I’ve been setting up karts for just as long and have tested just about every componet many times under all types of conditions at tracks from Florida to Oregon to Toronto to southern California.
The motor is good for about 10% of the total, chassis 30%, driver 60%.
We will work with anyone to help make them faster. But if they want to concentrate on the motor, I won’t waste my time.
