Finished the revisions to the braking system by mounting the new master cylinder, plumbing the lines, and the parking brake valve, bleeding. I like the new setup and it's much more maintenance friendly than the toe brakes.
Also changed the carb needle to a 2.5 and the air filter to a K&N at Jeff Schultz's suggestion, and reconnected the mixture and throttle controls, and cleaned up some cable routings ahead of the firewall. I love stainless steel ty wraps! Oh, and wired the carb to the intake manifold in case the rubber boot fails. Somehow the kill switch wire from the lower mag got disconnected and it was a Bee-yatch getting it back on.
