just a question? with the old pressure tanks getting few and far between, why couldn't a guy take a tank and install say a valve stem in it, pressurize it with a portable bicycle pump,hook her up and ready to go.the tank only runs under about 4 pounds of pressure anyway right?
I have a 1976 Merc 9.8 with the thunder bolt ignition.It had no spark on either cyl, I recently replaced the switch box with a used one. Now I have spark on top cyl. and nothing on the bottom cyl. so- I switched the wires on the coils and now just the oposite - spark on bottom cyl and no spark...
