I'm new here and just bought a Seadoo speedster 1999, twin 787, been sitting for about 18 months, one engine fires up fine but the other just fires on full choke at idle on one cylinder and the other cylinder seems to push fuel out/flood and not fire, if you add any throttle it stalls, carbies are new there are 2 good scratches on the rotary valve, was wondering if this sound like the rotary valve timing is out
