I'm used to set the timing with vacuum disconnected from distributor. Now my Ford made me wondering if this is the right method on our cars also? There seems to be at least 10 degrees difference on the balancer mark with/without vacuum at 500 rpm idle. Is this normal?
Distributor turns counterclockwise and motor clockwise when looked from front. My balancer has marks from TDC to 20 BTDC in 2dgr steps from left to right, and the marker on the block side is there. So I had too much advance at idle vacuum hose disconnected. To me it meant turn the distributor counterclockwise to retard advance. And what happened, I got even more advance! So I needed to turn my distributor clockwise, against it's rotation to retard timing. Something does not make any sense to me now.
Anyhow I set it to 6 degrees BTDC, but when I connect the carb vacuum it jumps to 22 BTDC. It idles OK but this bothers me. I'm running Pertronix II yet to my understanding it shouldnt play any role on this.
