Jim,
There are some good kart shops in town that can help you. Imi and Billett work on everything, I know Action is a Leopard dealer as well as Sac Motorsports.
If you do a search on Ekn, you will find a lot of information regarding Leopards. I have never run one (have raced next to a bunch) but remember seeing an upgrade kit or something like that for the starter contacts and brush’s. This forum is also a good place to get help. Shemerhorn, Welch, Ray, Poole, Furgeson, Samu, Burton or any of you Leopard guys. Can any of you help point him in the right direction? If it takes a starter kit and you don’t feel comfortable installing it, I’ll help.
It’s a good engine package don’t give up too easy, Come out and race.
Rick
