If too little enters the combustion chamber the engine will only be able to idle. Replace broken parts and ensure that fuel lines are properly connectedĪ go-kart engine requires the right amount of fuel and air.Inspect the fuel lines, fuel filter and fuel tank for any leakage.If it still bogs down, proceed to the next step. Once you’ve opened the choke, your go-kart should start running optimally again when hitting the gas pedal. Once the choke valve opens, air can flow through the carburetor, facilitating an optional fuel to air ratio. Locate the choke lever and twist it back to its original open position. If you have an external carburetor, then your choke is on the carburetor. All you have to do is set the choke to ‘open’ (sometimes called ‘run’ or ‘off’) on the go-kart engine.

If the problem is caused by a closed choke, fixing it is extremely simple.

In essence, a closed choke allows for a richer fuel mixture at the expense of air. A choke switch set to ‘closed/choke/on’ closes the choke valve, which restricts airflow through the carburetor whereby mostly fuel enters the combustion chamber. This is because a go-kart engine requires an optimal air to fuel ratio for it to run optimally. It’s fairly common to close the choke when warming up the engine, but failing to open it after a while can cause your engine to not combust properly, eventually shutting down. One reason why your go-kart engine can bog down after you start accelerating is when the choke is closed. Switch the lever or switch to the ‘open/run/off’ position.Locate the choke lever on the carburetor or choke switch on the engine.
