only 80 years old?? They don't make them like
they used to.? ?
Good work keeping this old stuff alive, more people need to know how
things work other than asking your phone to do it for you.

This is called a mixer valve.
It's function is to mix natural gas with the air intake
charge to fuel the engine.
The replacement valve assembly was made out of 12l-14 free
machining steel with a 6061 T6 poppet.
I figured that the aluminum was an ok choice because
technically this engine only runs about 40 hours a year now.
The valve stem bore is being opened up on a Bridgeport
vertical to accept the larger diameter replacement I made.
The 80+ years it was in active service finally wore it
completely out.
The pintle in the original photo trashed the bore in the
housing until the poppet broke off of it and shut the engine
down.

It's really cool to be an active member in our Association
and to have the skills required to keep as much of it alive as
possible.
The flywheels on this puppy are about 7 feet in diameter.
We use a Farmall M tractor to fire it up because the air
starter got away from it decades ago.
