Camshaft for 125-150 cc CG engines. On the CG, the camshaft sits in the crankcase and operates the valves in the head through lifters and pushrods.
- Replace it if the lobes are worn, there is scoring, heavy knocking around the valve drive, and loss of power.
- When replacing, check the lifters and the camshaft drive gear.
The camshaft is installed strictly by the timing marks: incorrect valve timing leads to poor engine performance.
