hi! my argos clutch from the engines output shaft is sticking. when i give it gas in will rev up to maybe 5500rpm and then i can see the clutch just snap onto the belt. once i get going its ok but starting is tricky, if i give it gas slowley say like 10 seconds the clutch will slowley engage the belt but i dont want to wait 10 seconds every time i stop! so how do i fix this?
