Hello, I am rebuilding my Stromberg 97 carb for my 37 Fordor. There is a spacer of sorts that was between the card and intake manifold. I have no idea what this is for nor whether I should keep it on the engine. Any clues??? The right angle copper piece has some kind of opening in it which probably feeds through an opening in the inside of the spacer. Is this a stock piece? Pros and cons of using it? Thanks, Gregg

Looks like a vacuum port used for a operation of a Columbia rear end. Was there any plumbing connected to it?....

I believe MG is correct about it being a vacuum source for a Columbia, as they required a large "volume" of air-flow to operate the large shift cylinder on the axle . My Columbia has an identical spacer. The only "con" to using it, is that you have TWO gasket surfaces to make leak-proof instead of just one. Unless you need a lot of vacuum-flow to operate something, it is rather pointless to keep it.

Me thinks it probably was the vacuum source for a South Wind gas heater.

Thanks for the swift responses. Nothing was connected to it, so it was probably causing a vacuum leak. I haven't started the car since I bought it a month ago. Still working on getting everything in shape for the big Day. This part will go into my bag of "stuff" for now. I believe the rearend in the car is a regular stock one, but will look into that also.

42 Merc is correct,don't need it. You might need shorter carb mount studs if carb wont tighten up good to manifoldPO may have installed longer ones to use the plate. Normal hardware stores carry carb studs.ken ct. You also get a little more ommph from a 48 carb as its a little bigger internally, jets,power valve are bigger than in a 97. ken ct.

That may be the case. My car doesn't have a heater now, but it appears that one used to be installed. More investigation is needed on my part. And yes, the studs are too long. For now I am using a 3/8" nut as a spacer. Eventually will replace the studs with shorter ones. My next journey on the path to get it started is to tackle the starter solenoid. It works, but gets hot after prolonged cranking (may be normal)... I just took apart the solenoid, not too bad, some pitting. Will clean it up and put it back together. Thanks, Gregg

1937, What jet & power valve size do you intend to use in the 97? Ken in Texas

You can install a # 63 power valve and main jets .048 from a 48 to a 97 and it will equal performance of a #48. No sweat on this. ken ct. Also use the longer accelerator rod on the 48. Their are 2 diff sizes of rods used on strombergs long rod measures 3.805 / short one is 3.645. I have all parts in stock if you cant find them. ken ct.

Interesting thread. I have a Stromberg 97 on the bench that I am rebuilding that has been on my '35 for years. Took it apart and cleaned it up last weekend. Turns out it had .045 jets and a 63 power valve in it. I bought a 65 power valve and was going to put that in because it always seemed to be running too rich. The 65 shouldn't make it run too lean should it? What spark plug should I run? Ken in Texas
