Fitech Rotor Phasing

mark your distributor body where #1 and #2 posts will align. then rotate your engine to the lowest and highest point you plan on running timing. If your rotor tip creeps toward that halfway point between #1 and #2, you are going to have problems. The reason this is so crucial for this system, is the rotor does not physically move as timing changes, so the older vacuum/mechanical style distributor is basically "self phasing" for lack of a better term. So at your base timing, you will want the rotor PAST the #1 post, so as the timing advances, it's not firing so early its snagging the previous post. I had to draw it out with crayons to understand it myself..
