You make a nice little brace between the two carbs with sheet metal 1/16"
plus then from the middle of the brace go down to the block at the flange of
the oil pan with a brace made of a 3/8" steel tube. I made an adjustable
screw at the bottom with a rubber pad on the end so that I could put just a
tiny bit of compression on the tube. Worked like a charm.
