The ski has 185 hrs and ran great until it started dogging out. I figured it finally gave up the ghost. This ski has seen allot of abuse with minimal maintenance. I checked compression all where within a couple percent. Then I check spark and to my surprise no spark in #2. I next swapped leads to check the coil and it sparked. So I would guess a CDI but would rather ask for advise than spend 300 on a new CDI and find out its a sensor or something. Any help is greatly appreciated. Thank you.
