Believe it or not, your gas cap is clogged up with dirt and debris. When a carburetor is unable to get a constant flow of air from outside, pressure builds up on the fuel tank. The fastest way to determine whether or not this is the problem is as follows.

As you are using your Mower, at that point when it begins to stall out, loosen the gas cap so that you release the pressure that is built up in the gas tank. If the engine begins to regain power, then you know it is a clogged gas cap. (Simply get a small wire and clear the breathe holes in the cap.) If the engine dies even after loosening the gas cap, then you may want to check to make sure the air breather is clean. ( A dirty air breather can cause the engine to over heat and stall out.)

If none of this seems to help, then it is probably a bad Ignition Coil.

Good Luck!

Cub Cadet has gas, has spark, has air -still won't start/run


Are you pulling the plug to check for wetness after cranking it a few times, WITHOUT using the starting fluid? Also, I would recommend using carb cleaner in place of the starting fluid. Starting fluid runs the engine VERY hot for a brief time and can possibly damage rings, valves, and aluminum parts.

check your grounds. I find many easy fixes by cleaning all the grounds around the engine bay. I would also check the ground at the fuel pump connector that wiring is prone to corrosion and breakage

if you take the carb solenoid of see if it has a black rubber cap on the tip. some times if you pull on it it will come off. if it does replace or cut the til off. don't try to force it off but if it comes off easily that may be the problem. as it is running it is sucked off by the vacuum inside the carburetor.
