I like that plan!:TU: BTW, to answer your question in your last PM, It's been ages since I last ran a single AFB, so I can't say how the Q-jet compared to it. The single AFB was replaced by the 2x4 in '82, and then I tried the Q-jet in '94. I will say the AFB setup did the best burnouts.:laugh: My notes show I tried #74 and 76 jets with CE and DU secondary rods in my blue 66. Spring tension on the secondaries is 1/2 turn. The red 66 I put on the road last year has a NOS Q-jet. I installed a wideband O2 sensor, and saw (and felt) a lean bog......that was caused by a low float setting. I did try another set of primary metering rods in it, but don't recall what I ended up using.
Walt - Thanks for the feedback. It sounds like my setup is more like Mike's - I've got a 7041304 service replacement carb with AK secondary rods 74 jets, 45 rods and N hanger. Sounds like I'm a step (or two) leaner both primary and especially secondaries. How does his run? Is his engine stock or modified?
Thanks to everyone who weighed in .. Carmen was able to locate the bracket for me (freshly plated!) and it fits perfect. Attached are some shots for comparison. In the first shot, the Q-Jet bracket is on the left and the 4GC/AFB bracket on the right. Notice the rounded corner near the locating "tang" and that the dashpot flange is closer to that "tang". On the AFB bracket the the flange is closer to the bolt hole. In the second shot the Q-Jet bracket is in the foreground. You can see that the dashpot threads are located higher and farther away from the bracket bolt hole.
