If you have been into this carb already, the adjustment on the float may have gotten changed. Float adjustment on most carbs is simply a matter of bending the little tab or arm that holds the float. This determines how high the gas needs to be in the bowl before the float closes the gas flow into the bowl. If the arm has gotten bent, the bowl could fill all the way up and the float would not shut off the gas, thus allowing the gas to run out the overflow and also into the intake and flood the motor with gas resulting in a not-start. I do not have the setting for adjusting the float on these carbs. It normaly comes with a rebuild kit. Maybe someone here knows the setting or has the directions from a rebuild kit. Maybe you started out with dirt holding open the valve and now have a bent float arm.
