Not wanting to tear it all apart I believe I'm going to put the hole thing on hold for the time being and drive it a while and then go from there. Appreciate all the input.
You should be fine all summer in Michigan with no Carb Heat. I hardly ever need it in Tucson. I do without all year. Possibly the 292 runs better in the high mid summer heat here. The '68 C/10 Stepside has no A/C either, and I need to work on the Vent Windows. Currently I have to rig a bunji cord on the wind wing to get full System 2-40 action.
Once, 30 or 40 years ago, when I ran the Holley 390 CFM with a sort-of Rube Goldberg bellcrank linkage -- I experienced real carb icing. It was Winter, and I was coming down from a ski trip in the White Mountains. I ran into a sleet storm before hitting Globe and my linkage froze up. I was stuck in high RPMs.
I managed to make it to my halfway hamburger stop by feathering the clutch. I stalled the clutch to stop the engine. After coffee and a couple of cheeseburgers, the higher temps at the lower altitude let the linkage thaw out, and the second half of the trip was nominal. I realized why Cessna 150s had a Carb Heat knob.
One reason why I converted to a cable/throttle linkage on the next rebuild.
