Adjusting the throttle can make a golf cart go 8 to 16 km / h (5 to 10 mph) faster. If you do it in an EZ GO stroller, you can probably go from 24 to 35 km / h (5 to 22 mph) of speed. This procedure will take you only 5 minutes.
Method 1 of 2: Fit a Common 4-Stroke Engine
Step 1. Squeeze the governor spring that is located on the motor of most golf carts to adjust its maximum speed
90% of EZ GO carts have single springs that limit engine speed. To increase the top speed of your golf cart, all you need to do is locate this spring and lightly tighten it. If you can't find it, you probably have a more modern model that is more difficult to fit, although this is rare.
Step 2. Raise the seat
Remove the seat aids, which hide the engine. You may have to unscrew the seat on a modern model.
Step 3. Remove the screws from the black plastic cover on the back of the seat
There are usually 5 screws on most models. The motor is located at the front of the golf carts, under this panel. Remove the plastic cover and set it aside with the seats.
Step 4. Follow the thicker cable coming off the throttle until you find a small spring wrapped around a metal rod
This is the regulator. The spring fixture will have 2 nuts (1 small and 1 larger) that hold it to the rod.
If you're curious, this is the buggy carb
Step 5. Loosen the small nut and tighten the large one
The more you squeeze the big one, the faster the cart will advance. You should start slowly, tightening the nut just a quarter turn at first. The engine can be overloaded if you try to start it too fast. Also, it can fail and choke if you are too impatient.
Step 6. Tighten the small nut on the regulator to hold the spring in place
Test the speed of the cart. Once you're satisfied with how fast, retighten the small nut. While testing, you should detect squeaks, glitches, or strange bumps on the cart. This means that you have tightened the regulator too much and need to loosen it.
Step 7. Replace the black cover to start driving
Put the cart back together as you found it and enjoy your ride.
Step 8. Keep in mind that adjusting the maximum speed of a cart will cause the motor to wear out faster
You will likely have to get replacement parts much sooner for a cart with a tight regulator. Also, any cart that can go over 30 km / h (19 mph) is officially considered a motorized vehicle, and legally requires seat belts and inspections. This detail shouldn't be a big deal, but it's worth keeping in mind.
Method 2 of 2: Adjust Other Engines
Step 1. Remove the seat and plastic cover from the motor
Sometimes the screws need to be removed, while some models have protruding seats. Put the motor on display so you can get to work adjusting it. If you don't have a center regulator spring, you can still make the stroller go a little faster.
Step 2. Locate the clutch pedal and hose
The clutch is the pedal (or sometimes a handle near the knee) that is used to put the car in reverse or change gears. You can adjust the clutch to send more fuel to the engine and move faster.
Step 3. Find the small metal rod right next to the clutch and attached cable
The length of this wire determines the amount of fuel that flows into the engine. Again, you have to remember that the cart motor will present problems the faster you make it go. Therefore, you should test each gearbox and detect thudding or choking noises to make sure you protect the engine.
Step 4. Loosen the nut that secures this cable to the metal boss to increase speed
You should see the cable elongate slightly, which will make the cart move faster. Tighten the nut to make the cart move slower.
Step 5. Note that you cannot adjust the regulator if this wire or spring is not visible
This detail is more common in modern all-electric motors. Many manufacturers (including EZ GO) do not want consumers to tamper with their engines and therefore hide the regulators in the spark plug ignition. It is very difficult to make an adjustment without ruining the engine, so you should leave this task in the hands of trained professionals.
