Hi, you were correct, I installed a new plug and it fired up and now it does run. My next problem is the idle, it has a rough idle it is up and down, I tried adjusting the air screw both in and out and it increases and decreases the idle a little but it is not a smooth run it still goes up and down, it's just a rough idle. Ivan ride it and it runs if ebut when I stop the idle goes back rough running, after idling a few mi utes I have to use the throttle to keep it running it wants to stop. Any suggestions
