The belt should be loose in the pulley and resting on the bronze bushing around the hub.

When the engine is at idle, the driver clutch pulley should not engage the sides of the belt. This action overcomes the force of the flyweights against the movable sheave and causes the driver clutch pulley to open, allowing the belt to travel a lesser circumference around the driver clutch. This action in turn causes the belt to force open the driven pulley, allowing the belt to travel at a lesser circumference around the driven pulley.Īs engine rpm decreases, the spring in the driven pulley closes the pulley forcing the belt to a greater circumference. As engine rpm increases, the flyweights push against the outer drum and force the movable sheave toward the engine causing the belt to travel at a greater circumference around the driver clutch. Knowing how they work may help you determine why yours doesn't. The flyweights in the clutch are sticking or the movable sheave is binding on the hub. Erratic engagement is most often caused by the driver clutch on the engine crankshaft.

Make sure the fuel tank is clean and free of stale gas as well.ġ. After the carburetor is free of all bad gas deposits it should be reinstalled with new gaskets in place. Remove all the rubber pieces including the throttle shaft seal (o-ring) before soaking. If the engine has been sitting up with stale gasoline in the fuel tank, the carburetor may require a soaking in carburetor cleaner to remove these deposits. Stale gas smells like varnish and leaves gummy deposits that clog the tiny jets of the carburetor. Stale Fuel: Gasoline in a vented fuel tank can go stale within 60 days. Faulty start switch or battery: electric start unitsĩ. Throttle cable is grounding to engine stop terminalĨ. Clean air filters prevent the engine from ingesting dirt and sand that damage internal working parts.ħ.
Check your filter on a regular basis, more often if you ride in dusty conditions. Clogged or wet air filter: The air filter functions as the lungs of the engine, if it's wet or clogged with dirt the engine is unable to "breathe" and it may be difficult or impossible to start.
