thanks sarge

If you aren't already doing it try turning the fuel tap to the 'off' position when not in use and see if that helps.

You could try some new plugs as they go off over time when sat in a damp motor.

Clean the carbs, renew the fuel filter and plugs - if it doesn't help then it's probably the valve clearances need doing.
