Although a lot of these kits run with the clip in the middle, if you are starting it with half choke and think it's almost too much, try going to the top notch. If you need more choke to start it, and it breaks into a four cycle when under light load (level ground, partial throttle) you are good to go.

One of my kits ran fine with the clip in the second from the bottom, the other in the second from the top. Neither one ran well with it in the middle.
