Tomberlin CrossFire 150 - Cam Chain

CAM CHAIN TENSIONER
The cam chain tensioner prevents the cam chain from being vibrated off when the engine is running. It is a
common feature found in most four-stroke engines.
Note: the cam chain tensioner is a spring loaded device and should not need to be adjusted unless you are re-
moving and installing camshaft.
