i am running platinum i believe autolite (always had good luck with them) and stock wires. yes it just sputters below 4000rpm at full throttle. up high, it runs like a champ! what should i do to remedy this? is it a spark problem, or a fuel problem? after the secondaries open up it runs like normal.
