I am in the middle of wiring my panel and have a question that some of you with more knowledge can possibly help. I have a carburetor engine (O360) that has a primer solenoid system. I have a boost pump that will pre-charge the fuel system prior to starting. I was thinking of using a switch that would turn on the boost pump and then have a momentary position to discharge the primer if needed. Does this makes sense? If so which switch would work? A 1-5 or a 2-51? When using either of these switches will the boost pump turn off when momentarily opening the primer? Does the boost pump need to be off or on continuously while cranking, taxiing and takeoff? Any help on this? Thanks
