I realized one choke wasn't opening, which prevented the secondaries from opening. Disconnected the chokes, but that made starting an absolute bear.
Also had to do the intake gaskets on that same engine. Found block off plates for the exhaust crossovers in there and that's how I put it back together. After I realized that extra exhaust heat is probably what heats the choke up...
Also, there's no way I was putting that heavy cast iron manifold back on, so we'll see what kind of difference this one makes...
