Check your timing, again, (I know, I know, I've been there, too). Then try your settings on your carb, I just rebuilt mine and it still doesn't run right for that reason. You can't always go with the settings on the factory stickers. Wear on the block and other things can cause you to have to adjust the timing to what may seem way out of whack. EGR vavle wouldn't be a bad idea, either along with other vacuum hoses.
