So is it worth it to rebuild Stromberg 48s myself or have them sent out to someone with proper tools? I picked up 2 yesterday and want to set them up with a third on an Offenhauser on my 327. Everything moves fine, the ****erflies are rusted though, and all linkages are there but really old looking.
I had 48’s on my 355 in my coupe. Be smart. Let someone do them that knows how to do the work. The emulsion tubes are most important to be removed and cleaned completely. If not, you are going to be lean. There are several reputable Stromberg guys on this site. Three 48’s with progressive linkage is a ton of fun to drive. My old setup
@uncle max is a Stromberg dude. He recently serviced all three of my 97's. And by serviced I mean he installed my new chrome bodies . I don't let many people play with my toys, he is on the short list.
Here are a quartet of 48’s that Uncle Max recently rebuilt for me. I provided cores, he provided parts and expertise.
I've never played with 48's, but have rebuilt many BXOVs and BXVs. Those 48s have been elegantly done. The red plugs and caps are a sign of a true craftsman. Cheers, Harv
You can do them yourself, depending upon your patience and ability. Emulsion tubes have been mentioned, but other areas to address is shaft wear in the body and ****erfly clearance. Excessive wear on the bodies where the throttle shafts are will result in a lean condition which might be difficult if not impossible to tune "out". Also pay attention to the mating surfaces of the bodies. I did a set of four that I ran on a Chrysler and when done, that engine ran like a Swiss watch. But it was a lot of work to get them to that point and included new shafts, reamed bodies, and ****erflies, jet sizing and matching, etc.

One of the reasons why the forum is so much better than social media. Buried deep back in my memory, partially dissolved in ethanol, is the thought that many years ago some flathead guy on the HAMB showed me how to pull emulsion tubes. A few minutes of searching, and I re-found Flathead Youngin's post from 18 years ago. Try doing that on FaceBook . Cheers, Harv
