i was wondering if anyone out there has had to replace a throttle arm spring and would like to know if there is a knack to it.i have fiddled with this thing a couple of days and cannot get it to tension up on the throttle handle.going buggy on this thing. does it have to be tight going around the little bushing once you get it hook to the arm or do you just put it down in ,line up the slot and tighten the lock nut up and then pull the end a little so it seats against the side.thanks for any help on this matter.
