I did an engine switch on it about 6 months ago. Today - when I went to about 2/3 throttle - it started to squeal - sounded just like a car fan belt squeal. It stops - but show up again anytime I turn right - and occasionally when I turn left. Anybody ever heard this - and have a solution for me? it's a bit tough to diagnose because the machine has to be moving - at 2/3 throttle or more to create the sound - so it's not like I can open it up and look for the source!
