What I thought were 160's turned out to be a 160 in the right carb and a 152.5 in the left. The parts guy sold me "two 160's".



OUCH! Man, I'd have a loud conversation with that dude! Glad you're gettin' everything ironed out though. This whole issue of the softer springs reminds me of the days when folks used to "upgrade" their Quadrajets and Hollys by overriding the vacuum linkage at the secondaries. The only thing that most of them ever accomplished was a huge off-the-line bog. The situation with our carbs isn't quite so bad, but I don't think I could live with a tip-in flat spot. Given the lack of an accelerator pump, your results seem to make a case for different carbs.
