Re: How to assess whether a carb is worth rebuilding?

If you have the round plunger, the kit you selected should work, but with one word of caution. The round style plunger came in 2 lengths (2-13/16" vs. 2-3/4"), if the kit comes with a replacement plunger, confirm the length is an exact match or there's going to be issues. What condition is the float? Is it in one piece and with no holes? Fun fact, 90% of all Rochester Bs are warped at the horn, so don't be surprised if it leaks a tad at the front. Have fun with the rebuild.
Ok so I'm not crazy. This carb has a flat post on the accellerator pump plunger. How do I find an appropriate rebuild kit? Everything is still soaking but perhaps later today I'll put things out and take some more pictures.
