Pro 22″ Self Propelled High Wheel Mower

Experienced gardeners share their insights in answering this question :
There could be water in the carburetor. To check to see if you have water in the carburetor you need to loosen the nut on the bottom of the carburetor (it helps to pinch off the fuel line to keep fuel from coming through the carburetor while you do this) and take off the fuel bowl and see what is in the carburetor. Most of the contents of the fuel bowl will drain out but there should be enough left to see if there is water or dirt mixed in with the fuel.
When you take off the carburetor fuel bowl check to see if there is any corrosion on the carburetor. This may have a white, chalky appearance or if it is varnish from old fuel it will look like the carburetor has a “gold” appearance. The correct color of the carburetor is a dull or flat grey.
If you find water in the carburetor bowl then there is a good chance that there is also some water in the fuel tank. You will need to drain the contents of the fuel tank. If you want to see what the fuel looks like you can drain it into a paint mixing cup or a clear jar. Start with a clean jar or cup, to make sure that you are seeing what is in the fuel and not what was left in the cup. lol.
When you have drained the fuel tank and made sure there is no water in it, I would suggest putting fresh fuel back in the unit. See if the unit will start and run ok. If the unit pops or sputters while the engine is running there may be some more water that will come out after the unit is run for a little while.
If the unit continues to not run or is not running very well you may have to clean the carburetor. To do this you will need a can of carburetor cleaner (spray) and a very thin wire to probe in all of the holes of the carburetor.
First, take the carburetor loose from where it mounts to the engine. Then take the wire and probe all of the holes in the carburetor, and also the holes in the fuel bowl nut (if any are present). Then shoot the carburetor cleaner through the holes to remove any loose particles of dirt or debris and to make sure the passages are clear. After you have done this, then you will need to blow through the holes to make absolutely sure that everything is removed that could be blocking either fuel or air from passing through the carburetor.
Re-install the carburetor back onto the engine, and check to see if the unit is running ok. If at this point the carburetor is still not running correctly, you may have to replace the carburetor. When you go to the parts counter you should have the MODEL, TYPE, and CODE off of the flywheel housing. These numbers are stamped into the metal.
