Rick,

The IO-550-N (the ‘nominal = Super ES engine) does not have the separate prime circuit / solenoid, and = the “prime” button is just a momentary SPST to the high boost on the Dukes pump. I = know at least some of the TSIO engines have the primer circuit / solenoid, as = this cased a fair amount of confusion between myself and Pat Brunner (N98PB = IVP). I assume the prime button on your engines needs to also trigger the boost = pump, but I’d check with someone knowledgable before I wired anything. = You knowe about assuming.
