You possibly have some oil congealed in the idle circuit from prologed non-use.
Try running the engine at about half throttle then block the intake with your hand until the engine just about dies. Remove your hand in time to let the engine run up again. This will draw any cr@p in the idle circuit thru and clear the sinuses so to speak.
If this works, try running the engine dry when yu're done using it, that will stop oil blocking the jets once the fuel has evaporated off.
