Milesmor Ford Timing Unit

Lynn, I believe most if not all 8BA dizzy complaints arise from having changed the carby, or fitted multiple carbies. This eliminates the venturi vacuum system which is built into the original carby, leaving only manifold vacuum to control the diaphragm. The two systems were designed to work in tandem, so if the venturi vacuum is disconnected, or split across more than one carby, the dizzy needs to be completely recalibrated. I suspect this is not well understood amongst rodders and often gets overlooked, so the dizzy itself gets blamed. Which is hardly surprising as it's radically different from the earlier vaccum system on the crab, which can be disconnected without noticeable effect.

Tony W. in post #7 you talked about the difficulty of finding TDC because of the offset of the crank. It seems that what you do is put pistons #2 and #3, exactly the same distance (up or down) their bores and you are right on TDC, #1. (and for no reason that is important here,#4 cyl. happens to be at BDC) (from page 204 of Pages book, Ford V8 Cars and Trucks 1952) A very good old book.
This just saves you having to work out the 1.5 degrees on the pulley.

I have made a bracket that straddles the two lower timing cover bolts from light angle iron. Unfortunately I did this without reading your post #7, and will have to revisit the marking of TDC.
Fortunately I have not yet fitted the heads.
