All automobile engines need to be rebuilt or repaired at one point or another, and a go kart engine is not immune to that. But one bad thing about that is the fact that they are smaller and may wear out faster. So doing tune ups and rebuilding are a regular part of go kart engine life.

Step 1 - Read Owner's Manual

Read through the owner's manual to know where the parts are located and what they are. Highlight important information and also refer to the engine, so you can recognize the parts. You may also want to highlight their Website URL and customer support number. Also check to see if they list where you can order replacement parts.

Step 2 - Drain Old Oil and Refill

Using the drain pin, drain out all old oil from the motor. Clean with the cloth and refill with new oil. Try not to spill the oil on the engine if you can help it, also pour it in slowly. Then close the oil tube and wipe down the whole engine.

Step 3 - Check Spark Plug

Locate the spark plug and inspect it for damage. You will be using the gapper to hold it and pick it up. If you see no damage, reinsert it. If you do find damage, write down the model number so you can buy a new one to replace it. You may also want to wipe it down and the area around it down.

Step 4 - Check Spark Plug Wires

Inspect the spark plug wires for any erosion or other damage. If you see any damage was done to it, write that down and order a new one. Otherwise if it appears to be fine, then leave it alone. However, you may want to wipe it down and make sure that it is not loose.

Step 5 - Clean and Inspect Air Filter

Use the owners manual to locate where the air filter is housed. Open it up with the proper screw driver and take a good look at it. Does it appear to have holes or other flaws? If not, go ahead and clean it with warm and soapy water. Allow to dry before putting it back in. Also clean the area where it is stored with a de-greaser.

Step 6 - Adjust the Carburetor

Using the proper screwdriver, adjust the carburetor in your go kart engine. Unlike modern day cars, they use a carburetor to control the fuel to air ratio. Over time, you will need to keep readjusting it for every 5,000 miles that you drive it. Try to turn it counterclockwise to get it at the best level  of optimization as possible.

After you do that, test the go kart engine to double check that it works. It should sound brand new again and be ready to drive. If not, redo the steps listed above and try again. If that still does not work, contact the manufacturer's customer support for more help or hire a professional to take a look at it.
