Hi, hargis here from Ft. Myers, FL. Have had my 66cc Chinese 2 cycle engine on a Huffy cruiser for 18 months and still running somehow w/o major repairs. So far, most repairs due to vibration related issues such as welds breaking, fender mounts breaking, coil wire breaking and spark plug loosening and popping out(nice surprise at 30 mph. Looking forward to future feedback.
