    02 GTI LE 717 won't start

    As stated ski wont start, The engine is new.

    Carb was rebuilt by Riva
    Rotary valve was aligned correctly with degree wheel set to 147 degrees
    Fuel tank drained, fuel lines flushed from old nasty fuel
    Oil drained new oil put in lines filled to oil pump
    fuels lines hooked up correctly to carb

    When i put a little fuel in each cyclinder from the top and crank it over it
    fires right up but won't stay running cause for some reason no fuel/oil is
    getting pulled in. So i know it's getting spark and will fire up.

    I've tried starting the ski with the fuel selector on res, there is about 5
    gallons of gas in it(new fuel), the engine turns over by hand very easy
    and starter has no problem turning it over. Any suggestions?

    Make sure all your fuel lines are on correctly(pulse, return and main). Check your pulse line for cracks and your fuel system for leaks. Make sure your gas cap has the oring in it. fuel system is pressurized buy the pulse line and the tank and all lines should hold pressure.

    Check for fuel flow by:
    removing the in and return lines
    blow into the return line and quickly plug the hole
    fuel should flow out of the in line.

    Maybe the carb wasnt rebuilt correctly. I would also verify the intake gear is timed correctly with the number 1(mag)cylinder.

    ok tried the blowing thru the return line fuel comes out the in line
    perfectly. took the carb all apart everything looks good in there as well. all
    fuel lines going to the tank/switch are correct as well, i'm at such a loss
    for what to test next.

    How does one go about testing the pipe the pulse line connects to? Would
    it be possible on a new engine for that to be clogged?

    I would put money that the rotary gear is out. If u want to try something else 1st the only other thing i can think of is putting a clear fuel in line going to the carb so u can see if it is pumping fuel. dump around 1oz of fuel in each cylinder to get the motor running and look for fuel going threw the clear line.

    Just stick a paper clip through the pulse line nipple on the case

    Try dumping fuel into the carb and see if it fires. that may tell you if the rotary gear is out.

    Is the top end and bottom end new? If just the top end is new maybe the crankseals are leaking and not holding pressure for the pulse line.

    If the bottom end was replaced maybe the crank seals are not in straight.

    Thanks guys for the help!

    I got it figured out tonight, i took a turkey baster and put it in on the
    pulse line to get fuel pulling directly into the carb and into the engine at
    which time the ski would start and then turn off because lack of pulse line
    surge from crankcase.

    So my next step was to take a pipe cleaner and push it down into the
    pulse line spout on the crankcase BINGO!!, YATZEE!!, JACKPOT!!

    Something small was in there whatever it was got pushed down into the
    crankcase. i'm ot to worried about what it was because it was kinda soft
    and didn't take much effort to push out, probably paint, or masking tape
    from then the engine was powder coated.

    for reference for anyone else having this issue here is an image of the
    spout i'm talking about that was clogged.

    ok so got the ski on the water today and the battery didn't have enough
    juice to turn it over but a few times, so got a new battery and cranked
    right over and started up idles and purs like a kitten, pulling oil and fuel
    perfectly at idle.....

    Then we get it out on the water and start to go and it ran fin up until
    about 10-15MPH and then it just bogs down and stalls unless you play
    with the throttle to save it.

    What do you guys think? The carbs have been rebuilt by Riva and i took
    them back apart and inspected them all is good, does the system want
    more fuel on the high speed and it's not getting it or is it something to do
    with the needle/seat? the Needle/seat didn't get replace in the rebuilt
    because they seemed fine..
