Teapot Carb rebuild

[dgmgohl]

Can anyone recommend someone that rebuilds teapot carbs to spec? Also, can you provide some listing for a replacement non teapot carb? Thank you!

I have been doing teapot carbs for a long time (two and four barrel). Since this is the Early V8 section, I assume you mean a two barrel Mercury or Lincoln carb. First four barrel teapot was the 1953 Lincoln.
For replacements other than original carbs, I have heard a lot of good things about using a two barrel Rochester 2GC. It would require changes like different linkage/fuel line hookup, a different air cleaner, and a distributor with a vacuum advance compatible with ported manifold vacuum.
If your talking about replacing a four barrel teapot with a different carb, a Rochester 4GC from an old Oldsmobile or Cadiilac (early 50's with same small base as the teapot). Would also require a distributor change with compatible vacuum advance for ported vacuum. Plus the linkage/fuel line differences. A modern four barrel like Edelbrock or Holley requires an adaptor, plus everything else I mentioned.

Hi Sal, you've provided info to me in the past, and I appreciate it. So you rebuild carbs? This is a 2 barrel off a Merc 1953 Flatty. What's the charge? And are they bench tested before their return?

I run Rochester 2G's on Mercury manifolds on a couple of my engines. If you mount them backwards, everything falls into place except the manual choke. Since the Mercury's had automatic chokes, I just leave them that way and they work just fine. I have done both the regular and divorced choke types and they both function correctly. The Rochester has larger throttle bores than the Merc manifold, so the manifold needs some modification. I bore mine out all the way down, but "bell-mouthing" the top may be adequate. On a stock, original car, I would have the Holley rebuilt. I use my '51 with a modified Merc engine as my summer daily driver, and for that, you can't beat the Rochester. One of them flows about as much as 2 94's or 97's with no linkage or balancing issues.

Properly rebuilt "teapot" carbs are hard to beat. That is a job for an experienced source.

Hi dgmgohl,


I will send you a PM about your '53 Mercury carburetor.

A question about the Holley 1901 teapot, please.


In my 1953 Mercury there are two holes in the intake manifold for de-icing purpose. Somebody in the past close the carburetor holes, so this passage are not working anymore. Are they only for de-icing or are they also useful for something else?
Thank you

Those holes are for heat from the exhaust crossover in the manifold to help with cold driveability.
To me, it's OK for them to be plugged as long as the choke on the carb is fuctioning well.
