warrior cuts out when given throttle

[stuman6669]

my buddys 02? warrior cuts out as soon as you give it throttle. it stays running, but it missfires and pops through the exhaust. it returns to idle and idles fine. the timing looks ok and we have swapped the carb with no change.its been sitting a while waiting on carrier rebuild, it ran fine before that. any ideas?

Does it have an in line fuel filter?

It sounds like a jetting problem but you said it did it with both carbs????

[stuman6669]

no inline filter. doesnt change with swapped carb. nothing in motor has been changed nor carb. exhaust smells a little like gas. im thinking maybe an electrical problem, maybe a rev limiter? thanx for reply, cool pic!

What is really throwing me is that it idles. If it was a CDI problem or something I don't know that you would even get it started.

How does the air box/air filter look? It maybe starving for air, possible it is getting enough air to idle but not for the increased load. Mice like to make nest inside of air boxes. I have a friend that practically sucked an entire nest into his motor.

What does parking brake switch have to do with carburetor or engine running smoothly ??

[Mustangmaniac]

if the parking brake switch is engaged the computer cuts throttle because it doesn't want to allow full capabilities if you were to hit the trail causing heated brakes and a struggling engine, kinda like a failsafe
