Sounds like you have a partially blocked pilot circuit on the left side, enough to let some fuel through but not enough to get the correct mixture if you are 2 turns out. New Amal's can come not cleaned out properly so the cheaper Wassells could have the same issue. You need to check the full circuit not just the pilot jet, for the pilot jet carb cleaner fluid is not enough, you need a 16 thou drill to clean it out properly.


This will help, the Wassell carb is a direct copy.
