Thanks for the responses. I'm not sure what button I have, so if I have 2 shims which I think I have I can remove the .1mm shim and be ok?

the simplest salutation would be to run 30%. The V2 is marked with dots on the button.

chill chill chill :cool:. i can tell you right now edd is a very bussy man. fuel orders are killing him as he is pushing out a weeks worth (year ago) a day now. he is a one man show and is a very bussy man with testing and trying to get fuel out. as far as calling him i usually try to get ahold of him around noon 1ish eastern time and i usually get through to him 98% of the time. if you cant get throught to edd try getting ahold of joe allesi (jpalessi) lucky 7. he can help you out with fuel orders or ebmods tech ???

If the motor has one aluminum shim (0.2mm or 0.008") and one copper shim (0.1mm or 0.004"), then yes you can remove the copper shim and run 20% nitro.

How old is this motor? When did you purchase it? Does it have a serial number etched on the side of the mounting tabs from Ed?
