Stromberg 97
Do all parts interchange between big logo and small logo Stromberg 97 carburetors? Are there differences other than the logo? Is the newer Grose valve an improvement over the needle and seat?

Re: Stromberg 97
About 18 years ago I put together what I thought was a matched pair of Strombergs for my hot rod sedan. I used the best parts from the pile, a rather extensive pile. And I thought I did a good job making sure everything was a matching pair.
I used good kits, and assembled clean parts, and got them running OK on the car. A few years later I was fiddling, thinking I could make it run even better. I wasn't sure what else I could do, so I sent them off to Uncle Max for a looksee. He informed me I had nice parts, but even though I thought they were all the same, I had a few mismatches. Evidently way down deep there are variations from different revisions you can't see from he outside. Tops not meant to work with some main bodies, and some bases got revised too. But Max set me straight with all the proper guts, assembled with new mainshaft bushings, and they worked perfectly straight out of the box. Moral of the story, is that yes there are differences to the parts that aren't really obvious. |

Re: Stromberg 97
Uncle Max set me straight about using the base with the improved idle circuit with the correct, notched venturi main body to go with it. He told me that otherwise you will have an idling problem with mis-matched components.

Re: Stromberg 97
Terry, OH, what you say may be true, but the notched Stromberg 97 bowls that I have are the South Bend variety.

Re: Stromberg 97
Does anyone have a link showing the differences of the old Strombergs, or what types were used on what years? That would sure be a good starting point, to be able to read up on them.
I have several boxes of Ford Strombergs, mostly NOS or vintage Ford reman's and I need to put together a pair for my '37. The only flatheads I've done were complete rebuilds of complete engines, so never had to switch pieces or parts. It's interesting, because I have one that physically looks exactly the same as the other typical Ford carbs I have, but it's cast Zephyr on the side of the bowl instead of Ford. Presumably for a Lincoln, but it makes me wonder what the internal differences would be. |
