Constant flooding

[VegetiveSteam]

No, it also is or was used on Snapper branded mowers which is now a part of Ferris I believe. It is a 18hp Kohler Courage motor. B&S bought it all in 2004 so technically it is all part of Briggs.

If it is indeed a Courage, it's not a CV493 so you may want to get a Courage manual.

As a temporary measure , you could try bypassing the fuel pump and see if the engine runs on gravity feed only (might have to fill the fuel tank). If engine runs well, then the carb flooding problem is elsewhere.

Please be aware most tanks do not vent outwards just inwards to break the vacuum. This why the needle and seat must seal properly or you have fuel leakage out the carb.

I had a carb gasket problem on a carb on a car 20 years ago and use the cut it method as needed when installing. I wrote the supplier _NAPA or who ever- woman called me from Arizona she said we have been specing/selling this gasket in the US for 2 years and yours is the first complaint. She said I tried it and you are correct we spec the wrong gasket.

I am on my 4th carburetor trying to stop my Kohler engine from flooding. I have purchased the cheapo carbs and progressively bought a better one each time. This last one is a Stens 520-118 to fit the Kohler CV493 engine. I have also replaced the fuel pump 2x. Nothing I do seems to help or stop the problem. You can start the motor, it will run long enough for more fuel to be pulled from the tank and then stop. After sitting for 5-10 minutes it will restart as long as the fuel is turned off. Turn it on the same thing happens. I did manage to get it running long enough to back it out and make one lap in my yard before stopping. This was accomplished by restricting the flow using the fuel shut off valve. I haven't been able to do this again. I am at my wits end. Could it possibly be the valves are so far out that it is creating too much vacuum through the ovhc port that pulls the fuel out of the tank to the carb? Can anyone help me please? My son in laws brother normally helps me but he is tired of fooling with it and I don't blame him.

Do you find any particles in the Float bowl? Is the fuel going into the crankcase as well? Drain the fuel tank and save a half cup in a glass container and leave that sit. Remove the Fuel filter if you have one and blow the line back into the tank with Fuel Cap off. Get All the Fuel out of the Tank (Turkey Baster works for this task). With a cloth around a stick try to mop the bottom of the tank so it is clean. Blow out line again with Compressor and re mop. Empty dregs of fuel from your portable tank and never try for the last drop.
Check inside it for 'clean'. Fill tank halfway, install new filter. Your problem has nothing to do with valves.
Good Luck. Don't mess with the float level.

Be sure the bowl vent for the carburetor is not blocked or restricted. Sometimes the air cleaner gasket or even the air cleaner plate restrict or block the bowl vent and allow the carburetor to flood.

Get a Stens 120-444 fuel filter in the line. It acts like dirt continues to invade the float and defeat the needle/seat. Also add Marvels Mystery Oil or 2 cycle oil to the gas. Ethanol is a solvent and makes the float valve stick, a bit of oil in the gas helps lube the needle so that it will seal in. Hope these simple steps help ( That fuel filter is larger and has the surface area while is an 11 micron fine fine filter even stops most water ).

Start by giving the model number and serial number of the mower.

No mention of the air cleaner. It could be partially plugged choking the engine. Remove the air cleaner and try again. Shooting in the dark here.

You are correct! It is not a Courage model, It is a Command model. I made a mistake. I knew it was the command series, but for some reason my brain made me type Courage. That happens to me a lot. Especially on my cell phone.
