My argo has always run pretty good in low gear but when I run high gear, fast and turn sharp it always starts running real rough, then the only way to keep it running is to toggle the choke on/ off. My local argo repair guy says its always going to happen because Im spilling gas over the venturi? Doesn't seem like the right answer to me! The only way I can get my Argo to run lately is to keep the choke all the way on. (It doesnt run great but it runs) If I take the choke off, it will die after a little while. Can anyone please help me? I think of how hard motorcycles and four wheelers are driven without similar problems.

Its acting like there is dirt in your carb.When you pull the choke out it will run.One thing you could try is readjust your idle screw and see if that helps. When this done and if it helps without taking carb. make sure you change the gas filter.

Your mechanic is doing a real good tap dance because he doesn’t know what he’s doing. To begin with Gasoline is a liquid and it can spill, like from your float bowl. Not enough gas in the bowl will cause fuel starvation. Too much fuel in the bowl will also cause problems, like running to rich to the point of killing the engine. Once the fuel makes it through the venturi into the carburetor throat it is airborne, and can’t “spill”. As long as you have airflow though the carburetor and fuel though the primary jet you will get fuel/air into the cylinders to fire. Because you can run the engine with the choke on that means that you have a blockage or other restriction in the fuel side of the mixture. The function of the choke is to restrict airflow. This has the effect of enriching the fuel/air mixture (in aircraft engines we use a primer system to get the extra fuel for stating). It also increases the velocity of the air going thru the throat, which lowers the barometric pressure in the throat across the primary jet. This causes extra hard sucking action to take place and probably is what is getting you the fuel you need to keep the engine running.

check your filter,or your fuel pump.then look for dirt or water in your fuel lines.
