Original Posted By: "Douwe Blumberg"
During my rebuild of my Stromberg carb, I learned a lot about them fromthis forum and elsewhere on the Internet. I wanted to share a few things I learned about mine in particular. It appears to have originally been a NA-S3A1 that was modified to a NA- S3B by using a file and a stamp on the housing. It has the correct venturi size for my C85, and the jet was drilled out to the correct size.and noted on the jet. The B is not supposed to have a mixture control,mine does.It also had a neoprene needle but the seat doesn't have a part number soI wasn't 100% it was the rounded seat. I went ahead and ordered astainless steel seat to compare. The seats are very similar and with thenaked eye is difficult to tell the difference. Externally, the length of threaded area is longer on the rounded seat and internally, it doesn't appear to be rounded, but an extra chamfered area for the needle to rest on. I attached a bunch of photos and I hope they will help anyone who may be working on one. I got the stainless steel needle and seat and fuel strainer from FresnoAirparts. I got the gasket set and new jet from AS&S.Curt MerdanFlower MoundRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/n1_1 ... __________
