Try a 36-T rear sprocket.

These carbs definitely give some room to fine tune your running.

I ran mine both lean for awhile, and I liked the way it ran smooth in the mid range. It just seemed to be a little too lean when under load or at 3/4 or higher throttle. I was worried I smoke something, so I went back to "a little too rich" which is where these engines were designed to be run.

If you do run lean, I would suggest a castor or castor blend oil fo' sho'.
