97 gti dies when you give it gas

[barons]

I have a 97 gti I just put a SBT motor in changed the fuel lines rebuilt the carb by passed the fuel selector and it still dies when you give it gas. I aslo put new plugs in . If you pull the choke when you give it gas you can run at about 40 mph. any ideas what it could be it is frustrating

When you say you bypassed the fuel selector, are you still running the fuel line through the filter? If so check the black O-ring on the filter and make sure it is properly installed.
Also pull the fuel baffle and check to see if the screen on the bottom is full of gunk.

You will be suprised how much a small thing like these will affect performance.
Good luck!

you test the pop-off on the carb/s. Obviuosly, fuel related, if pulling the choke, makes it run.

yes I am still going thru the filter and I checked the o-ring on it. when it runs at ideal the fuel lines are full. I did pull the fuel pick up out to fix the fuel guage did not see and dirt or gunk on it. I did not test the pop off I do not have a tester I used the same springs that came out ot the card because of that.

I have not done a leak down test how do you do that ? the ski will run with out the choke at idle and out out the water out of the water when you give it gas it falls on its face the first time then if you keep trying it does rev up. what pipe are you refering to not being connected?
