The photos are not great but can anyone tell me what this carburettor and air cleaner are off. Came in the back of a 46 pickup that has arrived .

Looks Mercury to me. Holley carb.

mfirth · 01-24-2018, 07:31 AM

If that's a Holly carb, 49-51 Merc. Olds had a Rochester that is very similar. mike

Can't tell from the pictures but if that Holley 885 has the automatic choke on the carburetor it is most likely '49-to early '50 Mercury or Lincoln.
No choke then late '50-to '51.
As I understand it it was also used on some later trucks(especially with that air cleaner)
Some truck variants had a speed governor.
There should be a number stamped on the top or the base that may help to narrow it down.
The ball end throttle rod connector would seem to indicate that it is early '49-'50.

International trucks also used this setup I believe.

Yep. It even showed up on 307 Chevies in experimental 1.25 ton military cargo trucks from the late 60s.

Mike, the Olds had a Stromberg WW backcraft, not Rochester.

The little tiny numbers for the 885 are on top of the accelerator pump protrusion that sticks up on top. Lincolns, Mercurys, and big Ford trucks used them. Big trucks like the F7 & F8 that had the 337 engine usually have a governor on the base. I'd say it's more likely a 49 Lincoln but I'd have to see the numbers to find out for sure. The ball on the throttle arm was usually 1949 & maybe some 1950 vintage cars.

There are two of them one has the number 4 49 the other has 4 51 stamped on it at the top ,what do they mean.

Probably month and year of production.

My early to mid year "51 Merc has the original carb on it. the car is a true survivor car, and only has 87K on it. the carb is a 885 Holley and has the choke on the carb with a hot air tube going to the manifold. It also has the overdrive trans with the half bell housing on it, not the ears with 4 bolt holes.

Deucekoop · 01-25-2018, 12:10 AM

How do you know if it is a holly

scooder · 01-25-2018, 08:32 AM

Because it is, if you remove the air cleaner, open the choke flap I think it's got a load of writing on the float bowl, you can see this through the choke opening.

This is a link to the late Holley manual for the 885. http://www.oldcarmanualproject.com/m...index_0001.htm

The first code 4 49 is 4th month 1949 should be the manufacture date. The other number set might indicate an upgrade. They usually have a single alphabetic letter stamped to indicate the altitude the carb was set up to run at when manufactured. There are significant differences between the carbs set up to run on the Mercury 255 and the Lincoln 337 due to the difference in power and metering requirements between the two powerplants. The Lincoln carbs had a 1 5/32" venturi where the Mercury ones had a 1 1/32" venturi. The early Mercury carbs say 1949 thru early 1951 had the automatic choke on the side where later ones had the choke component built into the manifold. Automatic cars had a dash pot. Trucks had the governor and so on.

Most all the 49 thru 51 Mercury air filter housings had a 90 degree elbow with a support bracket on the intake manifold. The Lincoln filters were a lot larger and much larger than the one in the photo on post #1 so I don't know what that filter fit unless it is a very early 1949 Mercury unit. I don't know what the truck filter housings looked like. There is also a possibility that it may have been made to fit other manufacturers engines but I have no information on that.

Thanks Dick, i just happened to see a carb advertised as a Rochester 4 Olds & assumed the seller knew what he was selling. Now that you corrected me, i remember back in the 60s the Stromberg on a friends 50 Olds...i think ? mike

scicala · 01-25-2018, 07:48 PM

A Stromberg WW isn't a backdraft type carb. I pretty sure the early Olds OHV V8's (303) used Rochester model AA and BB carburetors, the latter of which is the backdraft type (actually still a downdraft carb). Never saw a Stromberg of that design.
