How to Fix a Helix Go-Kart

The Helix is a go-kart manufactured by American Sportworks. The Helix features a 9.9 horsepower, 150 cc, four-stroke engine, an automatic transmission, independent front suspension and hydraulic disc brakes. Although routine maintenance keeps the Helix running smoothly for the most part, occasional repairs may need to be made. A trip to the shop is not always needed when the Helix stops running or performs poorly, as many malfunctions can be diagnosed and repaired at home.
