To clean the carb with Berrymans, remove the carb from the machine and squirt it down good to remove any built up dirt, saw dust etc. from the external surfaces. Hose it off with compressed air and lay out a shop towel on your bench to have a clean work area. Disassemble the carb as best as you can and try not to damage any gaskets, diaphrams, O-rings etc. Squirt Berrymans into all holes,orifaces, jets, and anything else that looks like it could hold dirt or crud. Blow compressed air into all of those areas to clear out any blockages and to dry out the B-12. Reassemble the carb, mount it back onto the machine, fire it off and adjust the fuel/air screws as necessary.
