My Monojet leaks at the accelerator pump too. The linkage was bent and wore the opening out a bit. After several days it leaks down bad enough that I have to prime the carb on cold starts. It would seem that since I've rebuilt my carb and experienced this problem that I have found others on the forum that have posted this kind of thread. I am not a Carb God but I do know how to set a float and I know that mine is set fine.It would seem that the linkage wears the casting.
Going from a 60 to a 105 sounds like a big jump but I am only used to Holley jets and am not sure how it translates to Rochester. Is your black smoke only at idle? Your idle mixture could be a little rich and that would mean that you have two problems and not one big one. Are you setting idle with a tach and vacuum gauge?
