I was riding and my 01 trailboss started running real weak and finally died. I managed to get it started and limped it home having to push it up hills due to no power. Kind of like bad or not enough gas.

Once home it would not start. I drained the gas and replaced plug. Disassembled and cleaned the carb. No good.

For some crazy reason I tried to pull start it and it fired right up.
It has no power....the same as how I limped it home. But it will run if you pull start it.

I can pull the plug and turn the ignition and see no spark. But as soon as I pull start it, it sparks.
I have pulled the black wire to the cdi, and about everything else but get the same results.

Any suggestions?
