Why does my golf cart backfire?
Golf Cart Backfires Because Fuel Mixture Is Too Rich. Always check the air and fuel ratio to make sure your engine is not receiving too rich of a fuel mixture. The following adjustments are an example of most carburetors, but you should look up the proper number of screw turns your model requires.
What is the ignition system on a golf cart?
Older golf carts used a set of points and a condenser to produce the spark needed to run the engine, but the more modern carts have a solid-state ignition system . The solid-state system utilizes an internal magnetic pickup device inside the engine that sends an electrical signal down the line to the igniter.
How to put air mixture back in?
When putting the air mixture screw back in, turn it to a soft seat and then back it off to the number of turns you took note of earlier. Bolt the carburetor back on to the engine head and reattach the cables and other lines. Replace the fuel filter and reconnect the line to the carburetor inlet.
How to clean a carburetor?

How to uncook a muffler?

Why is my piston red?
If you find that there is a buildup of coke on the top of your piston be sure and use a blunt tool to scrape it off because the piston material is very soft and can scratch or gouge easily. A scratch or gouge would glow red at the edges and cause just as much of an ignition point as the original issue would have and would defeat the purpose of de-coking.
Why is my throttle plate not closing?
If none of these accelerator cable adjustments solve the problem, then the throttle plate may not be closing all the way due to an obstruction or internal mechanism being bent. Unfortunately, the only way to find out if this is true is to remove the carburetor and inspect it.
Carburetor
More often than not, golf cart backfiring is caused by the throttle plate inside the carburetor being slightly open. This allows fuel to flow into the cylinder before the ignition system is activated to produce a spark for combustion.
Accelerator Cable
In almost all cases, whether it is a 2 cycle or 4 cycle engine, golf cart backfiring is caused by the accelerator cable being out of adjustment at the throttle plate of the carburetor. This problem has a relatively simple cure.
Adjustment
For proper symbiosis between the fuel and ignition systems, the accelerator micro switch must click BEFORE the throttle lever of the carburetor moves. The accelerator cable may move through the plate, but the plate itself cannot move prior to the micro switch click.
What is Backfiring?
Backfiring is when the combustion inside of the engine experiences an issue that makes it combust incorrectly. The result? An explosion occurs in the exhaust pipe, not inside of the engine as it should. This can cause damage to your clutch, piston rods, and even valves if you’re experiencing backfiring on a regular basis.
