MP Distributor Tuning Tutorial
i bought the unilite because all the descriptions of this MP distributor fail to mention the mech adv is adjustable. I would have bought this one instead of the $270 unilite.
anyways, the torx screws allows you to change the amount of mechanical advanced. you loosen them and you can use the mallory spacers to set the slot size. the length of the slots is like the slot in the old mechanical adv plate. bigger gets you more mech adv. shorter gives you less. it works really well. i love the unilite for this feature but i hate the LED in the unilite. id rather have the reluctor and magnetic pickup
