Dr. Bob,
If you're #11 is centered & you want to fool around, pull the afc housing & take your scribe & make a couple of scratches on the top of the pump, along the front edge of the plate. This will mark center so you don't have to use the black plastic piece. Then loosen the 2 screws & slide it all the way forward. Scribe a couple more on the front edge of the plate in the top of the pump. Now you've got center & all the way forward marked.
It's now easy to eyeball 1/4, 1/2 & 3/4 of the way forward for monkeying around. Just for grins, move it 1/2 the way forward & when you put the afc housing back on, tap it forward until it stops. You'll be surprised at the gain in low end & top end.
