I have a Coleman with very little use, but the battery is shot. I carried it for 6 years just in case my Leopard did not start. It has a 17mm socket taped on the end of the shaft.
Where are you located? What would you offer for it? If you send an email address, I’ll send you a picture.
Oh, yes. The motor in the kart was just installed recently after a full rebuild with dyno in 2007. It probably has less than 2 hours on it since breakin.
