Vacuum Attachment point on 261
Hi Bob
To your last point about the Vacuum Attachment point on 261 manifold in your Pat 11, look at the pictures below. In the picture of my 261 in the Pat 13 you can see that there is enough room for the side of the manifold. In the second picture you see the original 216 set up in Beauty which I think might be a solution for you. The vacuum for the brake booster comes off a spacer place between the carb and the manifold. Of course you would have to make a special one as the throat size and bolt spacing are different. An aluminum plate may be 5/8 or 3/4 thick would let you tap in with the vacuum facing straight back.
Cheers Phil
