It's a Holley 700 double pumper with mech 2nds. So you think something is stuck or gummed up? It could be it's been running on the gas that has been sitting all winter. I'll check the levels and clean it up. I dont think it's detonation, it ran last year fine and 10.25 is not really that high. But the pops are that loud and it's not the timing. No flames out the carb, just a pop and a shot of mist.
