Q Jet carb question

Tomco used to replace the needle-tip with a flat "disk" which was patented by the owner of the company. I haven't rebuilt a Q-jet in a while, but it's easy enough to check the kit at the auto parts store of your choice. I do seem to remember a "ball"-type, one-piece float valve for the 2-barrel Rochester's as well. The Viton-tipped needle-and-seat has always worked well for me, although there is another Q-jet post currently on the Forum which leads me to believe that a .047 orifice might be too large. I always thought "Bigger was Better"!
