what could be the likely causes and how should can i resolve.

Isn;t affected when screws on carb are moved.
could it be the main jet?

Blimey that's rich, if the carb mix screw is making no difference I would remove the mixture screw and see if the end has snapped off in the carb base


What size main jet are you using then?
