It will start but dies when I give it gas, what will cause that?


Hi Jeremy:
Opening the throttle will allow more air into the Carb.
If there is not enough gas available, that will lean the engine out and it will die.
I would recommend that you start you trouble shoot by draining and cleaning the carb, gas tank and fuel filter. Start over with fresh fuel. If the problem persists I would remove the carb and clean it carefully with compressed air, then try again.
If tat does not cure it, Reply as a comment to this post and we'll try some more.

Why does my ATV bog down and die when I keep the throttle wide open?


If you are lucky, you might just need new fuel filter and the fuel bowl cleaned out, and maybe new air filter. If not so lucky you need carburetor rebuilt. Backfire is usaully caused by engine running too lean ( too much air for the amount of fuel present). Fuel bowls get gunk in them and the fuel needles and fuel jets get varnished up. The accelerator pump gets worn out gaskets and/or bellows and doesn't give the right amount of fuel mist when you accelerate.

Full Choke is indicative of a motor starved for fuel

360 prairie atv engine does not rev up


If you've rebuilt and adjusted the carbs to the correct spec, and the air fuel mixture is right, it would be worth checking the fuel filter if one is present, as well the fuel pump (again, if present). These are typically the first place to look when you idle fine but die out on throttle.

As for the belt light, it depends on what it indicates. Wear? Tension? If the belt slips, or is too tight or too loose, it could also cause stalling under throttle. With the engine off and cool, check it for cracks, splits and wear, and give it a light tug with two fingers. It should have a small amount of play, but not enough to feel like you could pull it off. If it feels like a steel rod, it may be over tight.

If all of these things are fine, no clogged filters, etc, it's maybe time to look at the distributor, and recheck those carbs.

I have a 125 eton 4wheeler.it starts right up but runs out of gas.I tried to clean the tank petcock filter,but it was clean,so i put fresh gas in.Still the same thing,runs,but take off and it dies.I also...


Does it die as you twist the throttle or after riding it a short distance? I know its seems a silly suggestion but are you turning the petcock in the correct direction? Try the twister in all of the setting positions and see if a different one fixes the problem. Keep in mind if it dies on a throttle twist it might not be fuel causing the problem.
