Damn Thermoquads.

This Dart Sport is really not destined to be anything more than a fun street car anyway. It just needs to start easy, run well and perform at all rpm ranges.
I do have more experience with Holley type carburetors and agree that they are infinitely tuneable. They also seem simpler to take apart and clean if crud finds its way inside. I have cars that sit for months and the Holley equipped cars have been reliable.
This issue with the operational choke may convince me to consider ThermoQuads for future builds. I have a 71 Duster that will become a 340 clone. I plan to do what I can to replicate the entire 340 package. Those had ThermoQuads, right?
