I swapped out the CDI box from My model 98 super rat has the same box as the combat.working fine with super rat CDI box. Just occured to me today to try the swap. Super combat CDI box is defective.Thanks to all for your input

thanks for all of the suggestions and info. I took your advice cleaned all connections and ground still no luck. i guess i will bite the bullet and buy a new CDI box (Quite pricey) I checked the coil ohm resistance it seemed fine. Thank You all!

Thank you i will check to make sure its getting good ground i checked the coil with ohm meter seems to be ok

Hope someone out there can help. I have a 97 super combat was running fine when I parked it six weeks ago.Went to start no spark. I pulled the plug and grounded to head kicked it over no spark. each time i kick it over i can press kill button and it will spark once only after kicking over each time....
