Mine ran fast and since then I took off the flywheel weight. Maybe it will be even better. I have not seen too may at swap meets but will pick them up now, not that I need more motors. I don't mind made in China. It is kind of the new Made in Japan. They can stay there and work and seem to be able to get by. If they come here and get paid minimum wage, they would have a harder time. I think the quality is more up to the importers and their QC, and what they accept (and are willing to pay for) I have some Russian engines that are very very poor quality, and others that are better than anything else period. A $35 motor, and a $250 motor. Oh, the Chinese hired my son for a year. Something that no one here would do, and at work we had a few contracts with the Chinese that got us through some tough times. The U.S. pretty much abandoned us and then paid us less and less for the products.
