Hi,
I Just made my first kit the other day, and this morning had it running!
however, the throttle didnt work so i had to controll the speed with the choke. Then the chain came off and got wedged between the spokes and the sprocket, so after taking apart the chain and putting it back on i went and tried again.... but nothing D: No putt putt or anything. I was told by a friend to check the spark plug, but when i took the rubber wire off the top there was a small gold cap on the end with a small pin sort of thing on top which i believe snapped off of the inside of the plastic tube thing that goes on top of the spark plug. I cleaned the spark plug, and tried putting the tube thing back on it anyway and when trying to start it, once again nothing happened. So my question is, should i get a new spark plug and CDI thing, or is there perhaps another reason why its not working? 
Thanks.
