We bought a used Kazuma Coyote go cart with the gy6 150 for the grand kids. With info from this site we got it running. It starts easily and has plenty of power but I just can't get it to idle properly. It will idle for 5 to 10 seconds and then die, but will re-start easily. I can increase the idle using the idle screw but when I get to the point that it will stay running, the idle is too high and you can't shift from forward to reverse without shutting the engine off. I started the mixture screw at 1 1/2 turns and as I adjust it, it doesn't seem to make much difference. Using info from this site I have adjusted the valves, cleaned the air filter, new in-line fuel filter and cleaned the carb with no improvement. I put a new carb and new vacuum line on it, as well as a new intake manifold, still with no improvement. The FEV has power. Sorry to be so wordy but I wanted to try and list everything I have learned here and tried. Any suggestions would be appreciated. Thanks
