I only wish, Niel, that I could come close to getting it that clean. Scraped abit off the walls, it wasn't as bad as the '51 was. That motor had ring issues, though. Like Tim said, it is hard to really see what you're doing in there. Cleaned the sludge out of the drain holes, picked up the wayward keepers, and pumped the snot out of the foot feed. No choke, hit the button and fired right up. Then put the choke on for about five minutes until the frost melted off the base of the carb. Wayne
