Setting timing on a 225??

Sarge
My solution only applies to the late 225s. Once the dizzy is out, and you flip it over you will discover that the hold-down tab is bolted onto the underside of the bowl.
Found a pic of the underside so I see what you're referring to now. I've pulled and timed a lot of Ford distributors, and done so incorrectly more times than I care to mention. What do you mean by "limit your power timing"? Thanks for the clarification!!
