Gotthe new combo firedup and sounded and felt pretty good. Then I notice the secondary pumshot was frozen solid( same carb as before, been sitting a year). There didnt appear to be a problem with the transition between primary and secondaries.Plugs have a little color (dark grey/light black). Are my front jets too rich and convering the transition??? Im asking because im only running 70/78 jets on a 410 hp 351 with 10.25:1. Still have the power valve- 5.5 with 13-14 in at idle/10-12 in gear. Any thoughts??
