Stromberg 81 question I have 2 Stromberg 81 carburetor bodies that the accelerator pump hole is the same size as those in Stromberg 48, and 97 carburetors. These are not something that someone hogged out. They are as cast, factory sized. I know of someone else who also has 2 carburetor bodies like that. Does anyone have knowledge as to why these bodies are like that. Any info will be appreciated. Thanks, nick.

Re: Stromberg 81 question Is the Venturi size and also the base butterfly size as an 81? Uncle Max might know.Contact him.He is a member here.

Re: Stromberg 81 question just a guess of course, but...
if you're referring to the diameter of hole in which the the plunger sits...it's possible that the length of its travel (it is driven by a lever, after all) compensates. as it would be much more economical to change the pivot point of the lever, or make it longer or shorter or even change the size of the nozzle (spritzer) openings, than to have three different castings, i would think. :) |
Re: Stromberg 81 question Those 3 carbs 48,81 &97 have different CFM's and each has its own venturi size SO 3 different castings.

Re: Stromberg 81 question The top cast body marked 67 is from a small logo 97. You are correct the 81 accelerator pump is different from the 97, 48 & 40. I do NOT know if the the pump diameter is smaller. Max is the man!

Re: Stromberg 81 question Yes, The 81 accelerator pump piston is a smaller diameter than the other Stromberg models.

Re: Stromberg 81 question Could the 81 center bodies be "modified" to circumvent the rules of a "racing" series? Carbs had to be 81's but modified to perform like 48's or 97's?
|
Re: Stromberg 81 question It is pretty obvious which carb bodies are 81's - vs 48's or 97's, so I don't see an easy way to modify them to "cheat" the rules. All somebody would need to do is take a look down the venturis.
With that said, those who want to cheat find all sorts of innovative ways to do so! |
Re: Stromberg 81 question I have contacted Max Musgrove about this question. Max seems to think that some very creative person may have altered the carburetor body. I don't think so. I now have 3 Stromberg 81 main bodies that are as cast from the factory, and they have the accelerator pump hole the same size as those for model 40, 48, and 97 carburetors. I miss Bruce Lancaster, he was a fountain of knowledge.

Re: Stromberg 81 question Measure the venturi's and the base butterfly openings to compare to an "normal" 81.
|
Re: Stromberg 81 question I did this, and they are the same as a regular Stromberg 81.
|
Re: Stromberg 81 question You may be able to sleeve the bores back to the original size or try using a 97 pump.
|
Re: Stromberg 81 question Why not just use the 97 pumps?
|
Re: Stromberg 81 question As far as I am concerned, I will use 97 pumps. I would still like to know why these carburetor bodies were made this way.
