Hi, probably wrong forum, but maybe you can advise right one, blower is running fine but it clatters, and sounds like is coming from engine rather than the body of the unit, any ideas would be great! Thanx…

Try replacing NGK-CMR7H (3066) spark. I have seen them to cause a knocking issue when failing. And this series of plugs are bad to fail for some reason around my place.

Also make sure the fan isn't coming loose on the engine shaft
