Oh yeah!
My 3x1 manifold came this week.
Milo approves!
The 1st carb is taking a bath right now. I'll rebuild it nest weekend and throw #2 in to soak. I only have enough carb cleaner for one at a time. It's going to take a little modification to get hot water heat on this intake, but I have a couple of ideas. I'm going to go ahead and use these model 'B' carbs, since I have 3 of them.
