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…
Thank you for the info will surely check it outTry 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.
Thank you as well, will check this as well!Also make sure the fan isn't coming loose on the engine shaft
