How difficult was it to remove the crankshaft timing gear? Can be tough. Good sounds after all of the work, a good introduction to the more common Model A's miseries and cures. You might try an even slower idle with less advance and idle speed screw. When setting timing do it at the third notch in the up position. That way, when you're so inclined, you can go levers up and see how slow and quiet an A can really be.
