The E-Z-GO 4-cycle NGK Spark Plug provides the spark in the fuel fire and compression process. Those three things are the only three things that any gas engine needs. Sure, many components make these three things happen, but if you have a problem with a caddie and start with these three essential elements, you are bound to find the problem.Choosing one of these three topics is like picking the proper trail to go down in the woods. If you select the wrong path, you will know pretty quickly because things will typically test. We are looking for something to be off. On the fireside of things, pulling the golf cart spark plug out of the head and putting the cap back on it, then grounding it to the head, will allow you to see the spark. If you have none, start there. A new plug never hurt anyone. Call Buggies Unlimited today and get your golf cart back on the road.
