Actually, no, it idles great and runs well. Today a friend of mine and I adjusted the timing to normal, from about 10 degrees advanced. No smoke, no major shaking (Ok, it's a 48 year old truck. It shakes. And rattles. And occasionally booms.), nothing. When I measured it I realized later I had the choke on a small amount. I'm not sure how much this would affect the readings, it was about 85-90% in. I'm also thinking I have might have a low geared rear, because my dad (who had a '69 with a 250) said that it revved higher at highway speeds. Oh, and as for the carb, I did a rebuild on that a few months back. Granted, I only found the directions for the rebuild after I finished and put the carb back on the manifold.
