Need help tuning Quickfuel carb

I don't know which Digital 6 you have, but here's a little info from the digital 6 plus.

SPARK PLUGS AND WIRES Spark plug wires are very important to the operation of your ignition system. A good quality, helically wound wire and proper routing are required to get the best performance from your ignition, such as the MSD HeliCore or 8.5mm Super Conductor Wire. Helically wound wires provide a good path for the spark to follow while keeping Electro Magnetic Interference (EMI) to a minimum. Excessive EMI, such as the amount that SOLID CORE wires produce, will interfere with the operation of the MSD. SOLID CORE spark plug wires cannot be used with an MSD Ignition.

You might also want to try a basic plug gap, like .035"-.036" and go bigger from there.
Hope this helps.
