Pro Flo 4 Timing

So did you advance the rotor or retard it? I ordered the adjustable rotor yesterday so it won’t be here for a couple days. Interested to hear how it works on your engine.

I moved it the rotor CW until it was centered on the #1 post when the motor was set at 25deg BTDC. That's the middle of my timing range (15initial, 35 total) not including any vacuum advance. There was still more room for adjustment if I find there's still an issue at high vacuum part throttle (where I was having issues) when the timing will be as high as 40-45.
