eton viper jr

[shen]

I have a viper jr I bought my son,anyway its not getting fire to the plug.I can put a screwdriver in the cap and it has somewhat fire but none with the plug.cdi or coil?
I hate to buy a coil and it not be the problem,or a cdi...
I have tried bypassing the cdi revlimiter and it is the same way,,
anyone have any thoughts on this
