massive reconfiguration time again.

Hopefully some more time for test and tune on these new carburetors today. I'm going to start with trying to disconnect the secondaries. I do have some larger discharge nozzles coming later today but I don't think they'll be here in time for me to try. It looks like the rain will be here late this afternoon so this may be my last chance for some time..
The book that came with the carburetors did say that bigger motors with longer duration camshaft may need a bigger discharge nozzle so this could be one of my problems as well..
