RE: need help with mad force
try leaning out the low speed adj. screw. even thought the engine is set to be rich during the engine break-in it shouldn't be so rich that the engine will stall when idleing. another thing to check is the size of the air intake opening when the throttle is at idle. it should be about 1mm. any smaller and the engine cant get enough air to idle. its the same thing as running rich. it may also be a combonation of both possible problems. good luck with your mad force
