possible spark plug problem?

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.

Hi, i will try that , but first ill need to buy the stuff to do so and i live in a rural area so it will take a while to arrive, do you know of any quick fixes that would last me till the new boot arrives? I have tried tinfoil as mentioned in another thread but it still didnt seem to spark. Thanks.

Hi, i took off the boot and used electrical tape to directly connect the copper wires to the spark plug but still nothing... perhaps it wasnt the sprak plug causing the problem after all? Thanks.

Turns out i had my clutch lever too tight when it should have been fully out/loose. I loosened the cable and it now starts first time everytime. Thanks for all your help.
