Step-by-Step Guide to Tuning Up Your EZGo Golf Cart

A thorough tune-up of your EZGo golf cart is essential for optimal performance and longevity. This section provides a detailed walkthrough of the key steps involved in the tune-up process, ensuring your golf cart runs smoothly and efficiently.

Step 1: Checking and Replacing the Fuel Filter

Begin your tune-up by inspecting the fuel filter. A clogged or dirty fuel filter can lead to engine problems and reduced efficiency. If you notice any blockage or wear, replace it with a new one. This simple step is a crucial part of EZGo golf cart maintenance and can significantly impact the performance of your cart.

1976-1994 Marathon 2-Cycle

The canister air filter is accessed by raising and lifting out the cart seat, locating the cylindrically shaped airbox with a cap on the end, and unsnapping the two holding clips on each side. Remove the lid and then the filter. Inspect the filter for oil and dust, and if it is only lightly dusty, use compressed air to blast as much of the soil out of the filter as possible. If it is too dirty and/or oily replace it with a new one. Reinstallation is the reverse of these steps.

By following these steps, you can perform a comprehensive tune-up of your EZGo golf cart, ensuring it remains reliable and efficient. In the upcoming sections, we’ll explore DIY tips for golf cart maintenance and how to troubleshoot common issues after a tune-up.

Oil Filter Replacement

Changing the oil filter on an E-Z-GO golf cart is a fairly simple process. Here’s a basic step-by-step guide:

  1. Prepare Your Work Area: Make sure your golf cart is on a flat, level surface. You may want to place a container or some sort of catch basin under the oil filter to catch any oil that may spill out when you remove it.
  2. Remove the Old Oil Filter: Using an oil filter wrench, turn the filter counterclockwise to loosen it. Once it’s loose, you should be able to unscrew it by hand. Be careful, as the filter will still have oil in it.
  3. Prepare the New Oil Filter: Before installing the new oil filter, apply a small amount of fresh oil to the rubber gasket on the top of the new filter. This will help create a better seal and make it easier to remove the next time you change the oil.
  4. Install the New Oil Filter: Screw the new filter into place by hand. Then, use your oil filter wrench to tighten it. Do not overtighten the filter, as this can cause the gasket to break.
  5. Check for Leaks: Once the new filter is installed, start the engine and let it run for a few minutes. Check around the oil filter for any leaks. If you notice any, turn off the engine and tighten the filter a little more.
  6. Dispose of the Old Oil Filter: Take the old oil filter to a recycling center or auto parts store that accepts used oil filters. Be sure to dispose of it properly, as it is considered hazardous waste.

Remember, it’s always a good idea to refer to your golf cart’s owner’s manual for specific instructions related to your specific model.

Spark Plug Replacement

The recommended spark plugs are manufactured by NGK, number NGK BPR4ES. Locate the spark plug(s) on the top of the engine and remove the cable, exposing the top of the plug. Use a spark plug socket and ratchet to remove the spark plug and inspect the ceramic insulator.

2 Cylinder Spark Plug Location

The ceramic insulator should be ivory colored, light brown to brown would indicate the fuel mixture is too lean. If it is black in color, you might be running too rich of a fuel mixture, requiring an adjustment to the air/fuel mixture screw.

Spark Plug condition

Check the gap with a spark plug gap tool (cheap or free at most parts counters) and set this gap to .028 – .030.

Spark Plug Gap Gauge

Replace the spark plug and screw into place using the socket and your fingers to prevent cross-threading. Lightly tighten with the ratchet…no need to strip it out by tightening too much. Push the wire connector back on to the spark plug. Inspect the connector boot and wire for any cracking or damage and replace if needed.

Step 3: Fuel

The fuel filter is located in line between the fuel tank and the fuel pump. If the housing is clear plastic, make sure that the fuel inside is not dark amber or discolored from age. To remove the filter, disconnect the hose from the fuel pump by using a pair of pliers to squeeze the clamp ends together and sliding the expanded clamp further down the line. Raise the hose up and allow any excess fuel to drain back into the fuel tank. Put the hose back in place on the pump and secure the clamp with pliers again.

Fuel Filter Oreintation

Now remove the hoses from both ends of the filter, keeping a mental note of the orientation of the filter body, or take a picture with a cell phone…we don’t want to put this on backward. Tap the inlet side of the filter (the tapered end) on a paper towel-lined surface and see if any contaminants are dislodged and stain the paper towel. Your judgment will be needed here to decide if you need to replace the filter or not.

Return the filter to the gas line and secure it with the clamps. Sometimes there is a second filter located underneath the carburetor facing the front of the cart. Check to see if you have one and make sure it is also clear of deposits.

Air/Fuel mixture adjustment

2 Cycle engine: The adjustment screw is on the side of the carburetor and is parallel to the ground. You can identify it by the lock nut at the base of the screw. Loosen this and turn the screw all the way into a soft seat, then back it out one and a half (1-1/2) turns.

2 Cycle Carb Adjuster

There is a lot of discussion about the best setting for this, and on several blog pages, they suggest removing the drive belt first, then backing out the fuel adjustment screw while the engine is running. Once the engine is running at it’s best, the lock screw is tightened down, the engine is shut off, and the drive belt is replaced.

4 cycle engine: This has a plastic cap limiter on the top of the carburetor, and there is a minimal amount of adjustment needed or available with this model.

Step 4: Valve Adjustment

Check and adjust the valves every 250 hours or every year To keep the engine starting and running properly.

For the 295cc or a 350cc  twin-cylinder OHC engine. 1991 – Present

 NOTE: THIS PROCEDURE IS DONE WITH THE ENGINE COLD

Tools required: Ratchet with 6″ extension, 10mm socket, 10mm socket wrench, flat blade screwdriver, and a feeler gauge. Note: if the screw (C) has a square head instead of a flat blade slot, this takes a tool designed just for this purpose. You can, however, get around this by taking an old pair of pliers and grinding a V-shaped groove length-wise in the jaws (< >).

Remove the valve cover bolts in the pattern shown using a 10mm socket wrench and carefully pry off the cover, retaining the six spacer sleeves and the gasket. Set these aside and inspect the rocker arm assembly. Turn the engine by hand to point the cam lobe (D) down on the first rocker you are checking.

Valve cover bolt pattern

With the cam lobe (D) down, use a .004 feeler guage (A) and slide it between the lobe and the rocker arm as shown. If there is no resistance or too much resistence, loosen the lock nut (B) and adjust the set screw (C) until there is a slight drag sliding the guage in or out of the gap. Hold the set screw in place while tightening the lock nut. Recheck with the feeler guage.

Rocker Arm

For the Kawasaki FJ400 401cc 4-cycle Single Cylinder 1996 – Present

NOTE: THIS PROCEDURE IS DONE WITH THE ENGINE COLD

Tools required: Ratchet with 6″ extension, 10mm socket, 3mm hex wrench, feeler gauge.

Remove the four bolts (B) and carefully pry the cover (A) off, ensuring the rubber gasket does not stick and tear against the engine head. Inspect the gasket and wipe clean before putting the cover back on after the adjustment.

Kawasaki FJ400 401cc 4-cycle Single Cylinder Valve Cover

There will be two rocker arms to check. Turn the engine crank pulley by hand until the compression stroke is at top dead center. Insert a .004 feeler gauge (E) as shown between the tappet (D) and the valve stem. There should be a slight drag when you slide the gauge back and forth, and if the clearance is too high, you need to adjust it in. If you cannot get the gauge to slide in, then you don’t have enough clearance.

Kawasaki FJ400 401cc 4-cycle Single Cylinder Valve Adjustment

To adjust this clearance, use the 3mm hex wrench to loosen the center locking screw (C) and turn the surrounding 14mm nut with the wrench to open or close the gap. When the clearance is such that the feeler gauge begins to drag between the rocker and the valve, use the 3mm hex wrench to lock it back down while holding the 14mm nut in place with the wrench. Tighten to a torque of about 5 ft/lbs. DO NOT OVERTIGHTEN!
