Butch, make sure that you clean all the orifices in the carb. Also make sure that the tank and fuel line is clean.
With the electrical, my WD45 is converted to 12v system and I have a ballast resister inline from the battery to the coil, still use the 6v coil. It is a very simple proceedure to change the system over. if you search here on this site you will come up with diagrams on how to do it. BTW you will not be diaspointed if you choose to convert to 12v. Much easier to start and you have common batteries through out your fleet of equipment.
