Your E-Z-GO Gas 4-Cycle 350cc & 295cc Intake Valve is one of four total valves on the cart. You have an intake and an exhaust valve for each cylinder of the engine. This helps regulate the amount of gas and air mixture that makes it into the cylinder. More importantly, they make sure that the air mix makes it there at the proper time. Have you ever heard someone talk about timing being off? Maybe the conversation turned to something along the lines of "that sounds like it's missing." These are indicators that there is something wrong with the valve system. It could be as simple as a bad timing belt; it could also be a broken valve stem.Make sure you get everything you need for this rebuild. Unless you are elbow deep already and this is the one part you forgot, chances are, you are going to need more than just this golf cart valve.
