When I pulled my carb apart to send it to ZipTy for the carb mod kit, there was no spring above the hot start plunger. The shop manual was inconclusive so I assembled the carb without. I went for my second ride on this bike and the hot start felt not right. My buddy rides a CRF450 and his hot start lever has a positive return...probably a spring. Mine feels like a wet noodle. I look at the online fiche and it shows a spring. TT does not have a carb schematic for the '06 carb. Using powersportspro.com, its part # 37. Not much help I know... Can anyone confirm that there is in fact a spring above the hot start. I think there should be. Thanks.
