Yamaha Carburetor

What is a Yamaha Golf Cart Carb?

A Yamaha golf cart carburetor is the "throat" of any gas Yamaha golf cart engine. It works to blend air and fuel together at just the right amount for your Yamaha's engine to run smoothly. Fuel injected golf cart engines (such as QuieTech EFI) are available on many newer model Yamaha carts, but if you have an older Yamaha, you may have a carbureted example.

How a Carburetor for a Yamaha Golf Cart Works

1. Step 1: Air Intake: When your Yamaha's engine turns on, it creates a vacuum (sucking effect). When this happens air is drawn into the carburetor through your cart's air intake.
2. Step 2: Venturi Effect: Inside your cart's carburetor, there's a narrowed section called the venturi. When air flows through this tight spot, its speed increases rapidly, which then pulls fuel into the air as it rushes past.
3. Step 3: Fuel Mixture: Your Yamaha's carburetor controls this fuel flowing into the air based on both throttle settings and how hard you are pressing the accelerator on your cart.
4. Step 4: Ignition: The air/fuel mixture enters your Yamaha engine's combustion chamber, where it’s ignited (explodes) to produce power. Ideally, you have an optimal fuel-air mixture for healthy combustion, full power, and the best gas mileage out of your cart.

Yamaha golf cart carburetors can be adjusted for different driving conditions, and their main parts include the jet, float chamber, a throttle valve, and choke to help add extra fuel to get your cart going when the engine is cold.

When to Replace or Clean Your Yamaha Carburetor

Over time, your Yamaha golf cart's carburetor can get clogged up from old or bad gas and debris. You might notice a few things if your carburetor is going bad:

1. Cart runs rough: If your Yamaha shakes at idle or feels underpowered, your carb could be clogged.
2. Struggling to accelerate: Reduced torque and acceleration off the line for your cart can also be a sign of a bad carburetor
3. Yamaha won't start: One potential reason your cart may be failing to start is a bad (gunked up) carburetor. You may also have flooded your carb, which is a different issue that is pretty easy to fix.
4. Carb leaking: You may notice the seals on your Yamaha's carb are dripping.

Keeping your Yamaha golf cart carburetor clean and doing a minor adjustments every once in awhile can make all the difference in how well your carb makes your engine perform. If your gas Yamaha golf cart is running rough, we always recommend cleaning the carb first (along with a new air filter and spark plug).
