    1995 speedster to much fuel.

    I recently bought a 1995 seadoo speedster with the twin 657x motors. It was non running when I bought it once I repaired the mpem took it out to the lake it ran good and idle all day but as soon as I throttle it up it would slowly die out as if out of fuel. It was happening with both motors but would always restart after dying. Took it home removed carbs and cleaned/checked everything to avoid a long story I had to replace the carbs on one engine. The engine with the new to me carbs fires right up but the old carbs I cleaned keep having a problem of when I try to start the engine it just keeps spitting fuel out the carbs. I have it all set per manual. Tested the pop off pressure and it's set to 21 so I'm not sure what else it could be. Also all fuel lines have been replaced.

    Does the engine with new to you carbs run properly now? If your dumping fuel, I think that points to needle and seat, did you rebuild with OEM parts?

    I have not fully rebuild them just took apart/inspected and checked the seal on the needle and seat and pop off pressure.

    Id start with a genuine rebuild kit, maybe even go as far as a harbor freight ultrasonic dip and clean the carbs

    Do not put the pump diaphragm piece if you do get Ultrasonic

    Re: 1995 speedster to much fuel.

    Well got the carbs all worked out or what I thought they have all factory mikuni parts in the both engines where running great took it out to the lake it still idles all day long and can putt around under 3k rpms all day as soon as you rev up it holds 7k rpms for about 30 seconds then dies and even the engine with the new carbs does the same. Before I put it back together I blew back through the fuel lines to see if anything was plugged but could hear bubbles in the tank. Am I missing anything?

    Its starving for fuel...

    Remove fuel selector valves & run a line from tank to fuel filter then filter to carbs.

    Re: 1995 speedster to much fuel.

    Is that a common problem with these?
