If anyone out there has gotten one of these to run well/reliably, please tell me...I can't get the #%@$^ thing to run consistantly! I should have done more research on this motor before shelling out that kind of cash, but.... spilled milk. Is this engine defective? Has anyone been able to get satisfaction from Hobby Services in the form of a replacement that works or an exchange? ANY info regarding the tuning of this piece of would be greatly appreciated.[&o]
