+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ I used the momentary switch like Mark as seen in the upper left corner of the panel at http://www.krnet.org/mvn2004/040929271.jpg It worked just fine with no accidental actuation. The advantage would be if you have a carb failure you could use the switch to give momentary bursts of primer to keep the engine running, maybe. I don't use my primer any more after the carb fire. I now use the accelerator pump in the carb and then only after I have the engine turning over with the starter. I'm thinking of using the primer solenoid and an extra facut fuel pump I have to install a "smoke system" in the exhaust. I could just press and hold the little red switch for smoke or maybe a "press on - press off" switch. HOW COOL WOULD THAT BE ?? !!!!! Come to think about it, during formation fly-bys I need my hand on the throttle. Best make it a "press on - press off" switch. Larry Flesner
