ok guys ive has go motors for about a year now. Ive been reading on here that people are getting dang near or over ten minutes on a .21 7pt turbo. I can barely get 6 & 1/2 minutes on a runtime with good smoke and good power. Its def not too rich and not too lean. What are you guys doing to these things to make them run that long. Im running a 7mm insert, resealed the motor, carb is good. Just wondering what anyone would have in mind
