00 GTI won't start after carberator rebuild

[force61]

I just rebuilt the carb on my GTI and now I can't seem to get it to start. I can squirt starter fluid into the carb and it will run for a little bit and then die from fuel starvation so the ignition seems to be working fine. I pulled off the line from the fuel filter in front and it seemed dry, so I squirted fuel down and filled it up then put it back on. I then tried to start it with no luck and pulled the line off again and it took more fuel, repeated this step 3 or 4 times and still I can't get it to start. Any help would be greatly appreciated since I am kind of new to the whole 2 stroke thing.

One other issue I seem to be having is my key doesn't seem to want to turn on the ski and give me the two beeps every time I put it on. I cleaned the connections with no luck then I tweaked the side tabs in a little and that seemed to have fixed it, but now again it doesn't want to turn on. All the fuses are also fine so I just don't know what could be wrong since it is an intermittent problem.

Thanks,
Ryan

force, sometimes a bad/going bad, battery will cause the motor not to turn as "tuff" as b-4, this allowing no "vacuum" of gas. Hook cables to battery, from car/truk (not running), then give try..

With landyard/post...sounds you need new key...get/programmed at dealer, but take ski with you.

Make sure you hooked the hoses up correctly, also theres a chance you might be pulling the carbs back apart and using an air hose as a tiny piece of sand gets in there and its amazing the problems it will cause. Check your hoses first...as I assume before you rebuilt them you where getting fuel? also its funny but none the less make sure the fuel selector valve is on and that the upper fuel filter is clean.

Hey Timmy,

The Battery is brand new and is staying at 12.5 volts after each start so I don't think that is the issue. It idled fine before I rebuilt the carb, but as soon as I gave it any gas it would bog down and die so that is why I tore into it. I did find that the little filter screen was all gummed up so I think that should take care of that issue if I can just get it running.

Thanks for the Help...

Hey Custom,

I'm 99% sure I hooked them up correctly since I marked them prior to pulling them off. The top connection is coming off of the fuel filter in the front and the bottom one is returning back to the fuel tank. I did try taking the fuel feed line off of the little spliter 6" away from the carb and filled it with gas. Then I was pumping the throttle but I'm not getting the gas to empty out of the line, and the accelerator pump isn't pushing out gas from it’s little jet either. It almost seems like there is air in the carb that just doesn't want to pass thru.


Thanks for all the help guys, you are life savers.

According to the picture I just looked at your bottom one is the one from the filter and the top is to the tank return......thats what it shows in the picture...see if switching them that ways fixes it for you.

Man I'm such a rook. I guess I must have switched them up when I was swapping out the gray fuel lines on it. Now if I just could magicaly make a new key appear so I could get it to turn over I could prove how big of a dummie I am. Thanks so much for the help Custom, u r the man!!!!!:cheers:

how is the inside of the lanyard cap/key?

how is the inside of the lanyard cap/key?

It's (the key) pretty clean. The ski only has about 100 or so hours on it and has been sitting the past 6 years in an aircraft hanger in Arizona. I'm thinking maybe the lanyard was left on over a long period of time causing it to fail. It will work for a while and then all the sudden stop working, and as quick as it stopped working it starts again. This last time I was messing around with the carb issue and I had the key plugged in. It beeped once, lost power and I haven't been able to get power back to it since. It seems to be very intermittent and with out a common cause for failure.

Just an update. I did have the fuel lines mixed up so that took care of the not running problem. As far as the key not being recognized, it seems like it was just a bad connection on the main plug going into the MPEM. It also didn't have any Dielectric grease on the connection either. With all this though I took it back on the lake and is seems to be having the same issue once I put it in the lake.

When I first hit the gas it sputters and revs up and down and it really struggles to get on a plane. Once it does, it goes better but still doesn't seem right. I ran it for about 30 minutes or so and the longer I ran it the better it seemed to get, but it was still sluggish out of the hole. For the first few runs it would only get up to about 25mph and every once in a while it would hook up suddenly and surge to 30mph. As I kept running back and forth across the lake it slowly got better to where it was going consistently 40mph and surging to 45mph. The gas was drained and fresh put in about 3 weeks ago with stabil added to it. To me is almost seems like either bad gas, or still has a inconsistent fuel delivery issue. When I tore the carb apart the screen on the pump side was about 60% to 70% blocked by gunk so I assumed I had the problem nailed, but I guess not. Any help would be greatly appreciated.

Thanks,
Ryan

you replace the fuel line, or atleast, remove it, and clean it out. If stuff is built up into the filter, its still present in the line.

I changed out the lines going to the carb but then I ran out of hose so I just wanted to get tested out. The hoses I did inspect and the ones I removed were clean as a whistle though. The ski is pretty low time and has sat in a hanger for the past 6 years or so. Would the filter actually clog up again that fast? Also the external filter in the front is also clean as can be. I figured if it was the carb filter getting clogged up again then my runs would have progressively gotten worse instead of better. Thanks for the help though. Also has anyone put in a inline filter on the engine feed line just before the carb? It would be nice to clog up an external filter prior to the internal one getting all the crap. With that being said, does anyone know how many micron the carb filter is?
