New to me early 70s 400 is throwing what I believe is a LOT of soot out the exhaust. It starts, idles & runs fine except that it does not seem to 'get up and go' when I put my foot in it - meaning that I don't really feel the secondaries kick in.
Has a Holley carb with vacuum secondaries and an electric choke. The choke seems to work fine and drops out shortly after a cold start. Engine runs fine even prior to full warm-up. Any ideas as to what I should check? Would it be worth it to take to a shop with an analyzer? Sorry for the upside down photos - can't figure out why they flip after upload....
