i just got a go kart that has been sitting for two years. it won't
start. i pulled the spark plug and pulled the string, no spark. i put
a new spark plug in, still no spark. i held the live wire with my
fingers to see if there was anything, and i felt a spark. however,
every time i attached it to the plug, nothing.

so i figure weak spark. i take apart the whole string start thing on
the side of the thing looking for the points, i then realize the
points are outside under a little metal covering. i put it all back
together, halfassedly, but it still pulls enough for a start. i found
the points, cleaned them. still nothing. now there is no spark at all.
i didn't put two screws back on the big fan thing that's connected to
the crank shaft, that's the only thing i can remember not doing when
putting it all back together.

what can i do to get this thing to run?

also, i was told it needs a new clutch. how and where is the clutch on
a go kart???

thanks!!!!!
