Once again thanks for the replies [sm=biggrin.gif] but i think I am still missing the point [sm=confused_smile.gif]

What I am saying is, if I could get more clockwise movement in the servo arm (before it is stopped by the carb arm), then I could get harder braking (as i am not convinced my braking is hard enough). The only way I can see this can be done is by changing the spring on the carb arm to allow more movement of the servo linkage toward the carb.

Please bear in mind I am a total noob and probably need the most basic things spelling out.[sm=red_smile.gif]

Cheers
