My Unit Won't Start

A common problem we receive here at Killer Motorsports is when customers have issues starting their go kart. Whether it's fuel or electronic related, many of the typical starting issues are easy to solve. Listed below are a few of our most common solutions that you can check at home if you're having difficulty staring your go kart.


  1. Check power and fuel: When a go kart engine won't start, it is usually because of a lack of electricity or fuel restrictions. The first thing you'll want to do is check your battery and make sure it has a 100 percent charge. The next quick step is to check your gas to make sure you have flow to the engine. If after this step you determine that there is power in the battery and fuel flowing through the lines, you'll need to inspect a few specific parts.
    • Remove your spark plug and put the plug back into the ignition coil, hold the coil with your handle, and put the plug onto a ground or the engine, then have someone try and start it. If the spark plug doesn't fire, change your plug. If after this step the spark plug still does not spark, then you have a faulty ignition coil.
    • Next, you will need to make sure you have gas going to the carb. Take the gas hose off the carb and make sure gas flows from the lines. You might have to try and start the engine to see gasoline flowing if you have a suction-type petcock. If gas is getting to the carb, then try to start your unit for about 30 seconds. Once you are done with that, take the spark plug out and see if it is wet. If so, then the issue is not fuel-related. If it is not wet, then you need to do a carburetor clean and rebuild. See the section about carb maintenance here on Killer Motorsports for further instructions.
  2. Check kill switch: If you've completed the above steps to verify that there is battery life and fuel flowing, the next step you'll want to inspect is the kill switch or an issue with the ignition switch. Sometimes the ignition switch on a go kart can go bad, especially if it's exposed to outdoor elements for extended period of time. In order to complete this, you'll need to take it apart and check for power flowing to the switch with a battery tester. If you do not feel comfortable with this type of service, contact a local mechanic to check this for you or call our service department for assistance.

  3. Check ground wire connections: Finally, if you've verified that fuel and electricity is flowing and your kill switch has not failed or is stuck on, you should check your ground wire connections. To complete this, find your battery's negative terminal. There should be a wire that attaches to the frame. Make sure that wire is not frayed or cut. If it is, repair it and reattach.

Most of the time, finding the reason why your go kart won't start is rather simple. However, if you've completed all of these steps and still can't diagnose the precise issue, you'll want to contact Killer Motorsports for further recommendations.
