I did the Mainline kit but it was for the 4150 carb. I wanted the basics and that's what this kit provides. We've used all the jetting from 100 to 250 and it's dead on! Very happy with it.

I would recommend something like the Leash electronics single stage board to compliment it. It makes wiring super easy and comes with relays, etc. Very reasonably priced as well.
