I cannot find the rattle, knock sound. It comes and goes during operation. Idle to mid speed. Sounds like an exhast baffle if there is such a thing? Operating at a continous speed it will sometimes come on slowly then after a few min. in may suddenly stop. Then in a few min do it again.<br />A rattle, knock, -- cannot find any parts loose ??
