I picked up this superjet assuming the issue was carb related, rebuilt the carb and cleaned/inspected everything, checked out OK. Got it running just fine, but now it's having the same issue that it had before:
It starts right away, runs great, plugs look clean right when I start riding. I go ride for about 30min-1hour, it runs fine, if I kill it it starts back up just fine. However, after the ride if I let it sit for more than 10minutes it will NOT start no matter what.
I had this problem the other day, assumed it was too much oil in the pre-mix fouling the plugs, or the tune was fouling the plugs. I tried everything; cleaning plugs, adjusting low end screw, adjusting idle screw, playing w/ throttle while trying to start. Only after letting it sit for more than 2 hrs did it start and run again.
Fast forward to today, I ran all the "badly mixed" gas out, put some 40:1 gas in it with fresh plugs. Started great, idle is tuned great, drove for about 1hr. Come back and started to install a bilge pump kit, took about 1hr. Tried starting after that and had the same problem! This time I pulled the plugs immediately, looked fine. I also checked the spark, it looked somewhat weak. I will check the spark again after it's back to normal, then when it's not starting and compare them, maybe post a video up here.
I'm not idling the ski excessively when I pull in, and I also rev the ski a bit out of the water after pulling in every time.
Any thoughts? I'm thinking it's an electrical issue, stator possibly? I'll pull the stator cover off and take a look Sunday. If it's a fuel delivery issue, could it be the one-way valve? I checked that and it works fine.
