Another Strange Carb

[hanleyclifford]

Whoever can "make" this carb should get Gold Star with Oak Leak Cluster. Even some guesses would be interesting. It is a Zenith made in USA, cast iron.

Hanley, how about a pic from the top? Looks kinda like it could be a sync set up or a "barrel type" butterfly.

Governor carb for a 230 chrysler flathead stationary industrial engine.

At first I'd say ski lift, but not on Martha's Vineyard.

Is it a donkey for pulling boats up the ways? Or a genset?

Im gessing for some sort of pump..Something intended to run unattended for a while and to self modulate its throttle bases on a supply - demand structure. Big irrigation pump, oil or gas pumps, possible a pump intended for.offloading fish from a holding tank (menhaden, sardines)

The butterfly is definitely on a spring but the shaft lever has over ride capability. In addition to the throttle adjustment screw there appear to be two additional (adjustment?) screws at the narrow end of the aluminum housing.

That is for some type of governor?

[hanleyclifford]

Ever see a throttle control rod on ball bearings?

That is when things were made sturdy!!

I'm going to take the thing apart tomorrow to see if I can figure out how it works. It has no rpm connection so it must be vacuum actuated or something like that. Getting more intrigued by this thing. I'll report back.

Hey! I thought you knew. Not fair!

Where did it come from?

It's iron, overbuilt, updraft, and governed.
Must be Military and land-based. I'm sticking with my first post. You may find a tiny hole in the screw head at the pointy end. it looks like an aircraft safety-wire hole. That would be for a tamper-proof seal like on electric meters.

And another blown Hanley theory. There is no vacuum involved in the device itself but the movement of air in the throttle bore has two springs trying to influence the opening. The throttle opening is counter clockwise so the big (upper) spring is keeping it open while the lower appears to be just a stopper from idle.

Good eye, Russ. The military does like things to be tamper proof and troopie proof which usually means nobody can use it.

The Briggs and scrap engines in lawn mowers and generators just use a spring in the governor. No vacuum modulator in them. I think yours must have been attached to an arm with centrifugal weights to operate it.
This is consistent with an engine designed for a set speed, not load. Ie. to keep a genset at specific rpm for control of AC cycles(HZ)

Or a ski lift
