If you own a Yamaha gas golf cart, you may encounter problems with its performance from time to time. In this article, we will discuss common issues that you may face and their solutions.
Engine not starting: If your engine is not starting, there may be several reasons for this. The first thing you should check is the battery. Make sure it is fully charged and has the correct voltage. If the battery is okay, check the fuel level and make sure the fuel valve is turned on. Finally, check the spark plug and make sure it is clean and not damaged.
Poor acceleration: If you notice that your golf cart is not accelerating as it should, the first thing to check is the air filter. Make sure it is clean and free from debris. Another possible cause of poor acceleration is a dirty carburetor. If this is the case, clean the carburetor or have it professionally serviced.
Cart stalls when stopping: If your golf cart stalls when you come to a stop, this is often a sign of a dirty carburetor. Another possible cause is a clogged fuel filter. To fix this issue, clean or replace the fuel filter and have the carburetor cleaned or serviced.
Excessive smoke: If you notice excessive smoke coming from the exhaust, this is a sign that the engine is burning too much oil. Check the oil level and make sure it is not too high. If the oil level is okay, the piston rings may be worn and need to be replaced.
Cart won’t move: If your golf cart won’t move, check the parking brake. Make sure it is fully disengaged. If the parking brake is okay, check the transmission fluid level. If it is low, add more fluid. If the transmission fluid level is okay, the transmission may be damaged and require repair or replacement.
