haveing no luck with 80cc spark
hi guys ,,im new to the site so i would like to say hello 1st ,,,,now any help would be great i got a motor kit from downtown here and it ran for two days ,then died ,,,i have no spark , so today i went and got a new CDI (black box with the blue&black wires with spark plug wire) and still no spark ,,if i hook up a meter to the blue and black wire from the motor i have power coming out ,but now this is where i think something is wrong now if i use the meter to see if anything shorted out with the wires coming out of the motor they all act like there connected ,,,any ideas how to get this puppy running again

Try twisting the wire or wire cap into place. Sometimes these get unscrewed.

Re: haveing no luck with 80cc spark
If you have a OHM meter you can check the CDI and Mag, if you replaced the CDI as you said and have no kill switch. And you have checked the wire connections and made sure your plug wire is making contact witht he CDI...and I assume you have tried a new spark plug? Then there is nothing left but to replace the mag.
P.S. Also pull the mag side cover off and make sure no wire has come undone at the mag.

Re: haveing no luck with 80cc spark
make sure your ground wire is tight too.
did you check to see if you have spark from the plug?
