I have a 350 Warrior, it runs fine until i lay into the gas, then it justs dies out. I replaced the intake manifold because i could spray carburetor cleaner on it and i the rpms would ramp up. Well after sitting a few weeks in disgust, i am back on it. Now the only way it runs is with the choke half way pulled out.
Any help or a little direction to look would be greatly appreciated.

May still have an air leak or dirty carb from sitting around....

 

You need to get that carburetor cleaned out. Sounds like the main jet is a little dirty if you get trouble when throttle is applied. Possibly get a carburetor rebuild kit if it has been sitting for awhile.

 

I had the same issue with my Raptor,I cleaned my carb 3x's and still did it. I ended up boiling the parts in lemmon juice. It was amazing how much stuff started floating to the top of the pot of boiling juice. All the parts looked brand new and the thing screams now.
