I recently ordered a "80cc" kit from pcc motors on e-bay. Anyone know the actual engine brand? Its got a curved exhaust with a very short muffler consisting of a 3in dia pipe about 6 inches long with a stud in the center holding it all together. The motor was painted silver from the factory but does NOT have the curved clutch arm. Straight plug head and nt carb. Any info? I love the way it runs and am curious about the actual "brand"
