Hard to say...that is probably a new thread, as the tach jumps around. Im guessing a sending unit but have not done the research yet...feel free to throw out ideas.
The RPM's are high enough that when you initially jump on the sled at the begenning of the year, you hit the throttle, then back off.
It kicks in just past where I thought it should have kicked in.
I really have not jerked the kids off the tube yet, but it certainly does not make for a soft smooth start. The guy I got it from was into hopping up sleds, so Im guessing he tuned it so it would jump start out of powder at a high altitude (7000 ft +). I pull the kids around on the lake while ice fishing.
