Now that I have been able to create a 'HAT' for the newer style Rochester B so that I can use a 47-54 Air Filter Assembly, I am documenting the complete rebuild of the Rochester B carb. Rochester, in all of their wisdom, did not change the designation of their Carbs after 1954. They just changed the way the Air Filter Assembly is mounted and STILL called it a Rochester B.
So, the HAT is documented, and working on the complete rebuild. Takes about a full day at my pace to clean all of the parts properly for rebuilding. It's about a day or two from being done and then I can move on to the next thing. Thats too far in the future for me to determine what it is! LOL!
