First I would like to point out the Haynes manual has a pretty good writeup on this and can be bought for $1 at Autozoo. That's not a typo it's really $1.

So you put the crank at 23 deg BTDC on the compression stroke . Removed the delivery valve. And are rotating the IP while keeping up pressure by pumping the primer pump?

If it's squirting that's obviously not the start of delivery. What your looking for is the last degree at which you can get solid fuel to come out by priming the hand pump. Beyond that the flow will quickly start getting restricted. That's your timing point.
