Need help!!! I have a 2042LS - it sounds like to me at idle, full throttle, blades engaged, or still that a bolt is in the top of the block at the fan getting slung around. Like metal clanking. Once every 5-10 seconds. Can’t be a rod or something major because it’s not consistent right? Anyway I’ve done a complete service, taken the cover off and looked in the fan and can’t find anything loose or something jammed in there. When the sound happens sometimes it’s worse than others and the RPMs drop so I figure something is getting jammed in the fan. Can anyone steer me to a part or where to look if this has happened to them. Briggs and Stratton motor.
