I have only about 3 hours on this motor since I bought it and have gone through the whole thing top to bottom. Yesterday I experienced a new "quirk" The motor idles great, turns up full rpms, (fuel is fresh, with oil mixed exactly 50:1), but at between say 3200 and 4500 rpm there is a resonnance or rumble. It isn't severe but enough to hear and feel in the controls. One other thing to note. I replaced the waterpump yesterday, new housing, impeller, the whole "kit".<br />It went together ok, but I'm wondering if the hub in the impeller is not running "true". Any ideas?
