Brian, glad you out racing finally, hoping for the best. On the carb, remember the secondary's work on velocity of air thru the primary's, so if two stepping at around 3000-4000 there might not be enough air flow to pull the secondary's open. Don't forget to restrict the channel branching into the secondary's (better signal). More to come, we'll talk pm
