go kart runs at low idle then dies when I give it gas
 

Just what the title says the yerf dog runs at a low idle for a couple seconds then dies, and if I give it gas it dies immediately, im really hoping to fix it today so I could ride it while there is snow on the ground!Could it just be that its is around 30 degrees?? hope someone can help.

Oh were to start ! My first guess would be gas ! check filter , lines and connections.
Next I would pull carb , clean the jets, check for any water in the carb or debree !
My father taught me way back when all motors that run on gas are simple ! Only three things to check ! Gas , Spark , Air , .. One of those 3 will make a motor not run or all three lol

What type engine is it?

see if you can keep it running with just a touch of gas ---it may just need to warm up ---or else it may be the dreaded carb cleaning time. if it's a primer-bulb 6.5 tec or clone, it seems that once you hit 50 degrees or so and under you need to help them get warmed up for about 20-30 seconds before they'll hold idle.

i have a manco duece and it has a a 12hp moter with 6 upgrades and yet mine still does that too. im from michigan can cold weather effect this?

Mine too. Don't want to hi jack this thread, so I'll post another.

this might have to deal with the spark plug mis fireing. i would pull out the spark plug and see how well it is sparking.

thanks everyone got it running it was just a dirty carb!

good luck to ya
