Ok, it wont go with choke, since ur strangling it of air. The engine needs air so with choke it wont run. Ur only suppose to choke it when starting it up so lots of fuel goes into the engine. After it goes bump bump bump then u take the choke off.
Since u dont hav a cent clutch it will just stall wen u put the wheels to the ground. U need a cent clutch, ur only going to start it by pushing it and go about 5mph then start it and go. It would just go when u put the wheels on the ground since the kart weighs a lot.
Hope this helps.

No he means it only runs with choke ON if i understand what he said correctly, which means hes not getting enough fuel. Try cleaning your carb, and adjusting both low and high speed needles, start them both at 1 1/2 turns out, and adjust from there. Always adjust your low speed first, then go full throttle, adjust your high speed, and go back and adjust your low speed one more time.
As for the cent clutch, he doesnt need one, i like the idea of direct drive, just dont start it off the ground, you need someone to push you down a hill or something.
Whats your gear ratio by the way?
yeah see, I'm starting the engine with the back wheels of the kart of the ground and the engine starts and idles great, as soon as I lower the rear wheels to the ground the kart engine dies. The choke has to stay just about closed for the engine to continue idling, I've tried letting it idle to warm up for a while, and adjusting the carb.

Seems to me like ur not gettin enough air for a start. Clean the air filter in warm soapy water, once its clean squish all the water out and let it dry in the sun. Then spray a bit of wd40 on it and put it back in. Then u may have to adjust ur mixture screw, it may be running way to rich. U might need to back of the fuel mixture screw since it may be gettin way to much fuel. Check the plug as well. Should be a nice browny colour. If its socked and black ur to rich.
As for the whole puttin it on the ground thing and it stopping it will do that. U gotta have the kart moving then start it since it doesnt have a clutch. The shaft cant freewheel. Get a mate to push u down a lil hill or something then rip the cord n go.
XD Hope that helps.

Start simple before you go twisting mixture screws. Try some simple things to see if performance changes, then go from there.
1. Rubbing alcohol. Put a 1/2 cup of rubbing alcohol in your fuel tank (with it full of fuel) and let it run at varying throttle settings. This will do a few things, including scrubbing any water and condensate out of the tank and bowl, as well as lowering the effective flammable range of the fuel just enough to remove any pre-firing that may be taking place.
2. Pull the plug. Check it for color. If it's white, then that's a dead giveaway you're running lean, hence why choking keeps it running. Heavy and black, too rich, which could be indicative of timing problems, valve blow-by, or other serious problems. All said and done, you want it to look brown. Do this before you run the alcohol and any state other than nice and brown, clean it up by hand with a wire brush and regap. If I was smart, I'd have put this first.
3. Get a clutch. You're not going to get a solid feel for your scoot until you can run it under load. She may run like a champ propped up on a chair, but once you hop on, she may be a regular turd. You'll never know until you get a way to put her under load at higher RPM.
Until then, you're wasting your time.
