Just picked up a new cart and looking to see if anyone can help with any ideas. Have an '02 Ez-Go Workhorse with the 9HP Robin engine in it. Runs perfect. The problem is it basically has only one speed, HIGH. It hauls butt for sure, but you cannot go slow at all. If you do try to cruise at a slow speed, it is very jerky. It is as if you are on and off the gas very dramatically. Not sure if this is an adjustment issue or if there may be something wrong with a part on the cart. Any idea????? I would really appreciate any guidance.
