Stromberg Worn Throttle Shafts
Stromberg WW carburetors are notorious for having worn throttle shafts. Unfortunately unlike most carburetors, the WW wears out the shaft instead of the throttle body. As I mentioned, most carburetors wear the throttle body and while not a simple process, re-bushing the throttle body on these carburetors is very doable as long as you have the required tools, like reamers and good drill bits. We used to be able to get new throttle shafts to replace the worn shafts, but they haven’t been produced for several years now and finding a used donor carburetor is very difficult unless you happen to find one that has been sitting on the shelf for several years.
To our rescue is someone that I have consulted with many times in the past, “The Old Carburetor Doctor”. Jeff, the owner, has a fix for this problem, which he does when rebuilding the Stromberg WW. He tells me that he will repair your throttle body without a complete rebuild if that is what you want. He just asks that the throttle body be stripped down completely.
Here is what is says about this problem.
Stromberg WWs are no problem. Yes, the shafts are always worn, but we have developed a fix: I plug the (usually) free right-hand end of the shaft bore with a welch plug, and I rebush the left-hand (throttle lever) end with an extended bushing which allows the un-worn part of the shaft outside of the casting to be supported by new bushing material. Just look at a WW and you will see how it accommodates this fix; the factory should have done it that way in the first place!
