The three amigos are a great way to describe a few things working together toward a common goal. It's also a great movie, but slapstick aside, the crew members would be fuel, fire, and compression on a golf cart. If any one of these friends decides it's time for a siesta, the entire operation of the coach will go down in flames. Keeping parts like the Yamaha Cylinder Head Gasket for the G1 models in working condition will help the pressure side stay in good shape.The recommended compression rating is 125 pounds for two cycles; at 100 pounds, it's not going to run at all. Grab yourself a compression gauge from your local auto parts store and see where you stand. They are easy to use; all you need is to remove your Yamaha G1 spark plug and screw it down into the hole. If you are north of that magic number we talked about, you might have another issue. However, if it's low, you may want to get a golf cart gasket today.
