My family bought an '86 JS550 about 10 years ago. It was a great ski and didn't have any problems until last year. Basically started losing power until it wouldn't run. We did a compression test on it and it has 150psi in both cylinders. We pulled the intake off last year and rebuilt the carb and looked for reeds but I guess they don't have any?
My brother poured gas down the carb and got it to sputter but not fire worth beans. I thought maybe the flywheel key stripped out so we pulled it off and it was fine. In the process of that I damaged one of the coils because I put the harmonic balancer remover bolts in too far and now it won't spark. So I definitely need to replace the pulsing coil.
We also removed the fuel tank pickup from the "ON" and "RESERVE" side and I can blow through the lines into the carb meaning the fuel selector valve should work?
The spark looked ok but I'm no expert.
Anyone have any ideas what's going on or what we should check?
Thanks
