I installed the hot start only after the pumper carb. When I installed the new cams, I also installed the manual comp release, and beleive me, after a fall, it is a major help! Even with hot start, on a hill it's a pain in the a*s to go through the regular start drill. After a stall, the hot start is fine but if you fall and you flood it, that's where it pays for itself. BTW, save you money on the cams, not a great improvement!
