Well Jon, I spent about 3 hours searching last night, "Rochester", "Rochester B", "Rochester carb", "Rochester warp", “Rochester float bowl”, Rochester airhorn”, “Rochester rebuild”, “Rochester repair”, "carbking", "carburetor", and read thru nearly 500 hits. So ya can’t say that I didn’t try!
I only found one (1) post that referred to a fix for the warped castings, and it simply said, “ make a fixture to hold the casting and bake it at 400° for an hour.” Seems like a rather vague description of the fixture and procedure. It appears that I still haven’t found the elusive solution, I’m sure from what you have been saying that you have written more on the subject but I can’t for the life of me find it!
Also you refer repeatedly to “the better kits”. Just exactly what do you mean by the “better kits” and again, who is the one that is selling these “better kits”. I believe that I made reference to kits that I used when I was a kid back in the 50’s, that came with lo & hi speed needles, lead plugs so you could clean ALL the drilled passages and a few even came with a new float where that was a common problem. I’m sure that these kinds of kits are long gone but if there is a better line of kits available please let us in on the secret.
I’m certainly not an expert on carburetors and I just want to get a clear picture in my mind, so that is why I am seeking your opinions. I’m not exactly sure yet why you have such a strong aversion to the Rochester Carburetor, other than it is only held together with four screws, which certainly seems to be a weak spot. Other than that it seems like a pretty simple straight forward metering devise that, if restored properly should give good service, there are millions of them out there that have been in operation for decades. Even with all the things that were wrong with the “B” that was on my truck, it still ran amazingly well. The engine started and accelerated just fine and I was surprised to find the problems that I did when I tore it apart.
Granted from a performance standpoint there are many carburetors out there that are far superior to the Rochester “B”, but if someone is performing an accurate restoration I would think they would want to keep the original fuel system intact.
Thanks for you opinions,
