I have just uploaded a minor rochester carb repair item regarding the rochester carbs with the plugs in the bottom of the float bowls. Can anyone tell me which years used these plugs?

Bob,
If you are talking about the fuel well plugs on the Quadrajets...they had them from day one (1965 ) until they stopped making them in 1986 or so. I am not sure about the early 4GC 4bbls or the 2 bbls.

Thanks Bill
