@ematthews1 what make and model engine does this "Bad Boy" have?

by

Briggs & Stratton model #440777

@ematthews1 you do not get any fuel past the pump? You checked to see if the pump works? Checked your float bowls and fuel lines? The engine runs/starts with some starting fluid?

Possible that the model number is a 44Q777? It should be followed by a dash then 4 digits a dash and 2 digits.

Chosen Solution

@ematthews1 a big reason for the exact number of your model is that there maybe a fuel solenoid between the fuel bowl and the main jet. If that does not turn on you will not get any fuel. A good compete engine numbers and lots of pictures what you are working on may help to make a proper determination. Adding images to an existing question

TESTING SOLENOID

If solenoid does not click, the problem may be in equipment wiring, engine wiring harness or solenoid. To determine whether problem is with wiring or solenoid, perform the following tests in the order shown.

Test Equipment

A digital multimeter is required to test the solenoid equipment wiring.

The following tests will be performed with the meter in the V (DC volts) position

TESTING EQUIPMENT WIRING

1. With keyswitch in OFF position, disconnect equipment wiring harness connector from engine wiring harness.

2. Attach red meter test lead into equipment wiring harness connector. (side opposite raised rib)

3. Attach black test lead to a good ground

4. Turn keyswitch to ON position.

a. Meter should display battery voltage at connector. If meter does not display battery voltage, problem is with wiring harness. Check for loose or broken wire. If meter displays battery voltage, test engine wiring harness.

EQUIPMENT WIRING HARNESS CONNECTOR

TESTING ENGINE WIRING

1. With keyswitch in OFF position, re-connect equipment wiring harness to engine wiring harness and disconnect harness at solenoid.

2. Insert red meter test lead into GRAY wire in solenoid connector.

3. Attach black test lead to a good ground

4. Turn keyswitch to ON position.
