Have a 95 Yamaha wave raider 701 62t flywheel if that matters. Got the ski wasn’t running good cleaned rebuilt carbs no change on my way back to the dock I got to Playing with the fuel valve cut the fuel halfway off and it will open on up and run bout 50mph. Ok came home cleaned that replaced lines no change. Checked compression 145psi front an rear checked spark an it seems weak to me. Replaced coil jus cause I had one still looks weak any ideas
