It takes 3 things for an ATV engine to run, a sound motor, a decent spark, and a reliable carburetor. Most ATV engines seem to survive some real horrible treatment. The portable CDI box provides a good spark. This just leaves the carburetor. I have had very good luck with the PZ27 clone. In this video, I will show how to make a cheap adaptor to that it can be mounted in place of the Mikuni and Keihin Constant Velocity pipe mount type carbs.
