new to karting,bought a rotax last year only got out on it once and every was fine,bought it out at weekend and have got a overfueling problem.it would acelerate and then it would pop and miss ,i would have to come of the throttle to get it to pick up ,and one corner (if any one knows lydd the bottom corner before you come back on yourself)it would die coming out of the corner the only way it would pick up again was if i lifted the choke! it done this every lap , i took of the air filter and it was petroly,i was running a 168 jet which i understand is what they come with from new!i changed to a 160 and i think it made it worse!as i said i am new to go karting any help stering me the right way would be appreciated mick

I'm new to karting but have had alot of bikes etc in the past , I have exact same problem, mines is a junior, I have tried changing jets, cleaning out carb re-setting float level with a 3mm drill bit, bought a new plunger for float cut off, it's still doing same fault , it's throwing fuel out the carb air box is getting fuel in it aswell alot ? Any1 that can help? I'm getting to the stage now I don't even want the kart,

I found my problem some1 had changed the carb vent pipe thinking it was burst , when it's actually meant to have a hole in it
