As to routing for that breather, there is a large threaded hole in the back of the base of the carb; it is presently providing vacuum to the brake booster. Pictured is a large nipple in the front base of the carb - that is where the breather was routed from the valve cover. It would be a long way around, but should that be the connecting point for the recommended breather?
Btw, one of the reasons I never thought twice about that breather routing is because it had a nicely preformed hose. Sure looked like it belonged there.
Addendum: Upon further review, I might better off routing the brakes to that front nipple; it would make a neat loop of the breather by routing that to the rear base of the carb.
