In my book that sticking, spring actuated, exhaust choking, flap is a hazard and a waste of time to fiddle with. I took the advise of an old timer who worked on the old stove bolts for years. He informed me to slide in a grade #8 bolt through the manifold using flat washers, and double nut the bolt. Don't forget to use "Never seize on the threads. You could also tap and thread the shaft holes and install short bolts, this will cause even less restriction on exhaust flow. Seriously now, if you know and respect your old stove bolt motor, you are going to drive her nicely until you warm her up anyway.
