I got mine back together last night and had problems getting the second side down. I came up with a possibly new way to press the 2nd side of the carbs into place. I hooked a 4" c-clamp around the frame (loosely) as a fulcrum for a prybar to press on the plenum and they pressed right in. I put a thin piece of wood to spread out the force on the plenum. Lift on prybar, down goes carbs, much easier on the hands too! I guess you could use a piece of rope or thin chain instead of a c-clamp around the frame for the fulcrum. Watch for hoses and wires obviously.
