Bubbagates
To start with you need to see if a "S" is stamped next to the fuel inlet on the carb. The settings are different if there is a S. We started modifing the carb with a lighter spring to help the midrange burble. If there is not you have a standard carb, but I still need to know which one you have before I can tell you the settings. The model # is also stamped by the fuel inlet. The most common is a WT-76
