How to Change the Spark Plug in a Gas Golf Cart

A spark plug is a component of a vehicle used to ignite the air-fuel mixture, which is then used by the engine to produce power. If the carburettor starts sending wrong air-fuel mixture, then the plug can go out of order. Moreover, the repeated use of the plug can also reduce its effectiveness, which in turn, forces you to replace it with a new one.

Golf carts are very much prone of this type of issue, because they only contain one plug. Once you find out that the plug has worn out, you should it right away, as it can decrease the fuel efficiency of your card to great extent.

If you feel that the distance you set on the feeler gauge is greater than required, then you can apply some pressure over the hook using the gauge. On the contrary, if the distance is shorter than required, then you can use the gauge’s hook to pry the hook away from the spark plug.
