The carbs on these things must be pushed onto the int. manifold as far as they'll go, and then tightened (while still pushing it on).

You can also try squirting a thin stream of water where the intake man. and the carb join together with the motor at "idle". If it dies, stumbles, or speeds up, you've found an air leak. Note: just don't spray any water in and around the CDI or the magneto (L.H.) side of the motor (unless you've carefully sealed the mag cover and CDI wire rubber grommet which, btw, should be done before riding in wet weather)
