This go-cart appreared to be of quality workmanship and durability. I have had it for 4 days now, and have had nothing but problems. First, it would "turn over" every 20th turn on the switch, only to find a connection from the starter to the battery was broken. i changed this. The steering column bracket was loose from the factory, which caused the gear plate in the steering column to crack. I finally rigged this to where it would work. Lastly, the engine will not run at full accelleration. It "chokes" down and cuts off when you push the accellerator to the floor. I have contacted them at least 5 times. I will now contact them for a refund or a replacement cart.
