Before ripping the carb apart try mixing a carb cleaner,
such as Berryman's B-12 fuel additive, at about 50% with
gas and run the motor at all speeds for a while. Let it set,
without draining the carb, for a few says or so. Then run it
again with the same mixture. You may get lucky without
having to pull the carb apart. If not, be really careful when
taking it apart. Suggest working over a large clean towel.
Also, check for any possible air leaks at fuel line connections.
