yes this is with the hose off of the can/hose plugged so that we are only dealing with mech adv (slots/springs). Are you in brother!
Sure.. if you want to start at idle and work up to 3k-4k... I will bet the timing changes.. the vac pot is open.. you will have the mech advance for what ever its valued at... this is of course it isnt already advanced by time its idling.. do you know what the curve is(when the timing is maxed out.. RPM).. let me know these couple of factors
