Took the ski out today on the Bay and I really havn't had a chance to open it up this season yet. It runs fine all day and I cruised over to the river at 4800-ish and it runs with no hicups what so ever. I finally got some flat water and decieded to open it up and it revs up then it is like someone is shutting the power off and on after 5k?? Any ideas? Plug gap maybe? What should they be gapped at?
