    98 gts died

    Recently rebuilt card and changed all fuel lines on a 98 GTS I purchased. Had it on the water and was running great for a couple of days. Last day was on water for about an hour when all of a sudden it sputtered once and died. Was able to restart after resetting kill switch for about 30 seconds then it died again. Won't start now. Any ideas on troubleshooting steps to try and narrow it down as I'm brand new to jetski's.

    Sounds like it has scored the bore and lost compression in one cylinder.Need to test compression before anything else.Report back and let us know

    Checked compression on both cylinders (140-150) so I think they are both good. Checked spark and it is good. Can get ski to fire but most often will only run for a few seconds. Once in awhile it will run for a period but is real rough and when I give it throttle it bogs down. As mentioned the carb was recently rebuilt and had been running just fine before issue started.

    Is there any debris in the fuel filter cup or screen?

    I pulled carb back off this last weekend and filter was clean. It is an OEM kit (mikuni) on carb... It appears to be getting plenty of fuel. If I have flame arrestor off when turning over I can see spits of fuel out top.

    Make sure rotar valve is turning , pull carb and plugs , turn over by hand by turning PTO , should see valve moving thru intake manifold

    Ok I’ll check that but what would cause that not to turn out of curiousity?
