Briggs with a stuck valve.

Dave Wave · May 26, 2012

I have a 1967 vintage Briggs with a stuck open exhaust valve.

The engine has be parked 25 years.

I put some ATF and pb blaster on it (stuck open).

It will go down if tapped, but gets stuck open again.

If the ATF does free it up, should the valve be pulled anyhow to clean it?

Is it possible to remove the valve with basic hand tools.

Thanks

Dave

Yes the Valve should be removed to clean the stem and the valve guide. Once you have it out clean both areas with emery cloth. You can remove the retainers with ordinary shop tools if you take your time.

To clean the bore of valve guides, I use gun
barrel cleaning brush"s, of the closest size,
and spin it slowly with a variable speed drill,
and light oil for lube.

OBTW- Anybody have any tips/tricks to pulling the valve without the Briggs tool?

Thanks,

I have popped the keepers off with a screw driver on
Briggs engines. Takes a little picking and prying.

Got it unstuck. It can be done without a tool. Used a vice and a wire tie to recompresses the spring.

Thanks for the help!
