Forrestall Tool Repair

Ariens Compact 24 snow thrower

Engine would rev uncontrollably high (which can cause damage to the engine)

Attempted to adjust governor, but did not fix the problem indicating that the governor has failed

Opened the crankcase cover and confirmed that the governor had failed

First governor I have seen fail on these style engines

Walbro carburetor on an 18.5 HP Briggs Intek engine

Carburetor is leaking fuel

Removed carburetor and pressure tested the float valve. Failed pressure test. Float valve leaking.

The float valve stops the flow of fuel into the carburetor, once the float chamber is filled.

Installed new float valve needle. Slowed the leak, but still leaking. Needs new brass seat.

Brass seat is pressed into the carburetor body.

To removed, I use a 1/4-20 tap and thread the seat. Then, I use a socket I cut a notch out of, a 1/4-20 screw, and a nut (as a lock nut).

Install the socket as a spacer. Thread the screw into the brass seat. Then tighten the lock nut against the socket. Now by turning the screw it pulls the brass seat out.

Press the new seat in. Install the float, float needle, bowl, and fuel solenoid. Reinstall the carburetor and problem solved!

I’m sure they make a specialized tool for this, but whatever works!

Happy mowing!
