I thought you meant the original CDI, so you got a new CDI from Procom on Wednesday and its already there and installed? Everything worked fine for a day? It ran on both cylinders, had power etc. If so don't mess with anything until you call Procom. The CDI did not burn out your ignition coils if it all worked fine for a day.
Are all of your connections tight? Also simple things like the gas is on, gas is in the tank, vent tube is not crimped from tank being off then put back on.
