All these years I have used the best Rochester model "B" rebuild kits available. Since I was 7 years old I worked on a few Marvel Schebler's but not many and Clinton/Wisconsin rarely. However I always told everyone that I knew enough about carburetor's to leave them alone. There is one that I have rebuilt continuously however and that is the model "B" & "BC". Thats about it folks the rest are for pro's. Now as these old buggers are getting more difficult to find and the normal wear is on a one to ten with 10 being good condition. I find most at a 5, either bowl or air horn warped or really corroded inside etc. Shame on me if I have given anyone on this site wrong information. I say this because there are many new cures involving the flange gasket thickness. It seems that with many well used 216, 235 and 291 etc. the flange gasket can make a difference ( in three cases now). It has my confidence a little shaky. Can some of you guys give me advice? Would it be best that the few model B's that I have for retail to send 4 different thickness's or just quit. For so many restorers that want originality the old "B"s can be one of the simplest but cantankerous carbs most of the time. I believe it was Jerry that routed me a while back to Mikes 45.7 minute rebuild site. Forgive the long narrative but I'm not feeling very wise this a.m. Advice from the gut please. Doc. ohwell
