My kit has various springs gaskets, pins, screws and both needle valves, hiGh and low. So I'm guessing it is a complete rebuild kit. My only concern is the metering level. I never heard of that so I am going on Walbro website. Hopefully they have some info on it. Thanks for responding to my post, I can't wait to open this carb up, it is like a metal rubiks cube, and there is no visible float. Fun fun fun......thanks again
