I purchased one off eBay that was all aluminum (no plastic whatsoever) and it came with a rope (not steel cable) pull handle. It failed after 5 pulls! The clock spring jumped inside. I took it apart, reinstalled it, and it worked for a bit, but after 5 miles, the motor caught the wind up mechanism and tweaked the spring so bad it had to be junked. The ebay seller was excellent, and refunded the full amount after viewing pictures I had sent. So, I'm just seeing if anyone has bought one recently, and had success with it. If so, where did you buy it from? I'm using a 66cc 2-stroke on a Schwinn trike, and the owner has some pain in his hip that prevents him from pedal starting it sometimes. Appreciate your input guys!
