The fuel line leaving tank to the box is your fuel pump,it may not be working,take the line from the tank to pump and check to see if you have fuel flow through that line,if you do reconnect it and disconnect line leaving box to carb, push start button to see if you have fuel from pump,if not,check to see if there is a vacuum line connected to pump,it may be vacuum operated,you can also just run the fuel line from tank straight to carb to see if it will start,then you will know if its your fuel pump.

Scooter not getting gas to carb.


Silly question, but are you sure you are getting gas through the line? Could the line from the tank be plugged? How about the tank port?
Is there a fuel shutoff?

I can not start my J1940 190cc craftsman lawn mower, its not getting gas, although I have a full tank


Hello,

If you are sure that the mower is not getting fuel, you can also check the following items:

1. Make sure the strainer inside the fuel tank isn't plugged. This can happen after several seasons of use. You will have to remove the fuel and possibly the tank to check. Another way is to remove the hose from the bottom of the tank but be careful - remember this is gasoline and very flammable. Fuel should run freely from the tank and can be drained into another receptacle while you're checking.

2. The fuel line from the tank to the carburetor. After several seasons, fuel lines can swell internally and prevent fuel from reaching the carburetor. This is not that likely but is possible.

3. The carburetor - it may be necessary to remove the fuel bowl to check to see if the float or the inlet valve is stuck. You can try to lightly tap the fuel bowl with the handle of a screwdriver to see if you can un-stick the fuel valve. Do not use a hammer and do not strike the fuel bowl too hard. While you're at it, check the air filter. This should be changed or at least cleaned annually. The carburetor bolts should also be checked to make sure they are tight.

As a general practice, it's a good idea to run the mower dry of fuel for winter (if you have winter in your location). You can also add a product called "Stabil" to the fuel to store the mower for the winter. This product keeps the fuel from spoiling which can lead to sticky parts like the carburetor float valve.

See what your owner's manual says about adding fuel line cleaner to the fuel tank once in a while. Don't use too much.

Sounds like contamination has set into the fuel shutoff valve on the bottom of the fuel tank, or the fuel cap vent hole is plugged. Test the fuel line that comes from the fuel tank. First turn the valve off, disconnect the fuel line that feeds the carb, insert the fuel line into clear small container, then open the fuel valve to the on position and look for fuel flow,now turn the valve to the reserve position and check again for fuel flow. If these test fail to yield fuel try the procedure again this time with the fuel tank cap loosened and check for fuel flow. If in both tests the fuel fails to flow then the problem can be isolated to the fuel valve/tank outlets or the fuel line to the carb.
