I?ve just got the electric primer system from Van's and have a question:
Being cautious about orienting all solenoids the correct way up, e.g the starter solenoid installed so it won't get engaged by pulling g:s, how do I install the electric primer solenoid? Is it with the "big nut" up or down?
I don't want extra priming when doing loops or something. :)
