The E-Z-GO company officially stopped producing its 2-cycle golf carts in 1991, when the 4-cylinder carts were introduced. However, for a few years, these engines were produced in limited availability in some golf carts and utility vehicles. One of the easiest ways to determine if an engine is a 2- or 4-cycle is by the number of spark plugs. One spark plug defines a 2-cycle engine, while a 4-cycle engine has four spark plugs.

When reassembling one of these 2-cycle engines, the most important thing to keep in mind is to not overbore the cylinders to a larger diameter. After compressing the springs into the cylinder, one cannot rotate the cylinder. This ensures that the rings will not break. The ratio of oil to gas is important on a rebuild to ensure all the new parts work smoothly and efficiently. A high grade of oil combined with regular unleaded gas at a 128:1 ratio is the proper mix. After rebuilding the engine, a break-in mix should be used. This simply means that an extra ounce of gas should be added to the oil and gas mixture.
