Hello everyone! New to the forum. Kind of sad I just came across it. Glad to be here though. My son has a fox vortex go kart with the ex17 robin Subaru engine. Recently it stopped firing. Took carb apart, cleaned throughly, replaced spark plug as well, still nothing. Tore carb apart again and cleaned again and still nothing. Elected to spend $20 on a new carb. Still the same issues. Will run on choke for a couple seconds. Any help would be appreciated. Thanks!!

Try shooting a blast of starting fluid in the intake. If it runs on starting fluid you have a fuel delivery issue. Hopefully that $20.00 carburetor is good. Collapsed fuel line, restricted fuel filter, debris in the tank restricting flow where the outlet is in the tank, vacuum leak causing low suction. Those engines have a fuel shut off valve also, it's near the carb. Check if it isn't stuck closed or clogged.

Here's a Quick Start Guide.

Could even be a weak coil or spark module, flywheel key. Ground the spark plug and see if you have a strong blue spark. If it's orange it's an ignition problem. Not much else left to check.
