A carburetor regulates the flow of air and gas into the engine cylinders. If your needle is stuck it won't allow fuel to get to the bowl. This can be caused by bad gas and results in fuel not being able to reach your cylinders. Replacing your carburetor will allow your engine to perform top notch. We recommend flushing your gas tank to insure your Yamaha golf cart is operating with clean gasoline. You might look into performing a general service so you have a clean air filter and fuel filter also. We carry equal to OEM quality Yamaha golf cart carburetors for G1, G2, G9, G14, G16, G19, G22, and G29 Drive Yamaha golf carts.
