Well it was all fine. ran great. retarded my timming a tad and i started getting a VERY bad miss. so i went back to my old timing, still misses. it seems like a vac leak but i tested ALL lines/gaskets w/ carb cleaner, no change. i thot it mite be wires cuz when i played w/ my plugwires, it went in and out. new wires, no help. what could be causing this?
