I have an 05 SuzukiVinson 4x4 LTA 500Fquad that was running PERFECT last time it sat for 1 year. and now when I start her, it idles withchoke on but dies immediately when turning the choke off or give it gas.

I have...

1) taken the carb apart cleened and blow out all ports inspected all parts (it looked very, very clean inside) and cleaned everything just to be sure.
2) put it back together and it still does the same thing.

3) I then took the carb apart again and REALLY went through every part, making sure everything was clean and in excellent condition.
4) I also took the petcock valve off and cleaned the screen (it too was very clean) and made sure fuel flow was good.
5) put everything back together and it still does the same thing.

6) installed a new plug and still does the same thing
7) reseated the carb seals and tightened very tight to make sure no air was leaking...

Still, won't run off choke...

It's seems odd that it ran PERFECT before sitting, and now mysteriously won't run unless choked.

What should I do next? [align=right][/align]
