Anyone know this carb??

Bill

It is a slide-valve carburettor of some sort.

I.e. the carburettor barrel does not have a hole and does not rotate for throttling.
The barrel is a slide-valve that moves laterally, together with the tapered fuel control valve, to control both the throttle opening for air; and the area of the fuel-orifice.

I have a similar looking item on an OPS .60 engine.

I do not identify the engine, but it looks like a late '60s-mid '70s rig.

Looks like maybe a Picco.....? (engine looks like maybe a Super Tigre?)
Kind of looks like an r/c car carb...and might have a home brewed linkage?

Well gentlemen, I know how the carb works and I also know what the engine is. Would anyone know the maker of this carb?
Picco is a possibility.

Thanks

Is'nt there any writing on that engine ? Picco did have those sliding carbs but so did many other car engine makes.

That looks like a RC Car slide valve carburetor on a model airplane engine. The needle valve sticking up like that tends to be a giveaway. A number of different brands made carbs like that too. But it does have some similarities to Picco, OPS, Ofna and some others though. The complicated direction changing parts for adapting it for airplane use is interesting. I hadn't seen that before.

Earl is right. That upward needle is car practise. Had'nt noticed that.

It's just a ST 56 Reg.

Thanks Earl, I'm thinking Picco or OPS as well, maybe off a boat engine.
As soon as it decides to quit raining I'm going to run her up and see how it performs.

There's a nylon flange fitted to the intake which seems good and tight.

Bill

Webra maybe.

No way, Craig.

Webra had their own sort of slide-valve carburettor.
It was called Dynamix and its slide-valve was flat and worked differently in that the fuel-control 'needle' moved in parallel (not in its center, like in this carburettor's cylindrical slide-valve) to the slide-valve, within the fuel inlet tube.

Here are a couple of photos.

The engine is not a Webra either, even though their Black-Head did wear its muffler similarly...

A lot of fellers blew off the DynaMix as junk simply because it had an, "oh Lordy" extra adjustment. It happens to be a fine carb. I bought this Webra .91 specifically because it has a DynaMix carb.

I haven't seen a webra in atleast 20 years, but its the only air motor I could think of that came with a slide carb.

Wasn't webra the ones who also made a rotary valve four stroke?

picco used slide carbs on their air engines as well. thinking that OPS did too but not sure.

As I wrote, I have an OPS Ursus .60 engine with one at home, Dave.

When I get my camera back from repair, I may post a photo thereof here.
