I'm really not getting how you could bind up that secondary plate deal.
The last thing you would do is set the metering rod tips down into the fixed jets.At that point the hanger would be down flat on the cam arm. You can slide the whole deal fore and aft to check everything before you put the hanger screw in place.

Danny did a nice job on that deal. I never did get that fancy. I just took a small chunk of a Walmart bag and cut a couple of x's in it, then stuck it down to the gasket with a spot of chewing gum until I got the top was screwed on.
That works fine ,and doesn't restrict or bind the swing of the rods like the old tape trick did.
