Question and Answers

Q:

How do I install a new electronic ignition on a Briggs and Stratton 422707?

A:

Remove the blower housing from the top of the engine. There are 4-5 small bolts holding the blower housing to the engine block.

Remove the 2 screws holding the ignition module to the engine block. Adjust the module so there is .010-.012 clearance between the flywheel and the module.

Q:

Briggs&Stratton 18hp Riding mower. Model # 422707

A:

Thank you for your question.

I am sorry you are having a problem with the tractor. The engine does not have a safety switch. If the engine will only run when you pour gas into the carburetor, I suspect the fuel pump filled with oil. The pump has a line that goes from the engine to the bottom of the pump. If the engine is tipped over, oil will run down that line. I recommend taking the pump apart and cleaning it. The image below shows where the pump is located. Click on the image to enlarge it. While cleaning the pump clear out the hose between the pump and engine. Once it is clean check the operation.

I hope this is helpful. Please let me know if you need further assistance.

Thank you for using Manage My Life!

Q:

My treadmill circuit breaker trips after 15-22 minutes of use. Do I just need a motor replacement?

A:

If the motor is not making a noise or sparking, it is probably ok. It is normal for the motor to get too hot to hold your hand on it.

The circuit breaker may be weak. Circuit breakers get weak if they are failing.

If the walking belt is worn or needs lubrication, it will cause the motor to draw more amps and heat more than normal.

Lift the walking belt on each side and look at the walking board. Check for wear on the walking board and belt by running your hand across both. If you feel any roughness or worn spots, that part needs replacing.

To test the walking belt lubrication, do not turn the treadmill motor on. Set the elevation to the highest level. Stand near the front of the walking belt. Push yourself firmly toward the rear of the treadmill. If the belt is properly lubricated the belt will take you to the rear edge of the treadmill and dump you off on the floor. If you move and stop, the belt needs lubricating.

The part number for the belt lubrication kit is 219168. You can buy it at [www.searspartsdirect.com]. The cost is around $4.00. The application instructions should be in the package, but in case they are not here is how to apply the lubrication.

Turn the walking belt until the belt seam is along the top of the front roller. Raise the belt on one side in the center of the walking board front to back as high as you can. Apply ½ the tube of lubrication to the walking board in a zig zag fashion moving from front to back. Move the belt until the seam comes up on top of the rear roller and lift the belt again and put the rest of the lubrication on the walking board in the same manner. Turn the treadmill on and walk on the belt for 10-20 minutes. Walk all over the belt to distribute the lubrication evenly on the walking belt and board.
