I got a head start on the weekend this afternoon. Switched out the carb on the 53, going back to the original Rochester without the auto-choke. My first carb rebuild and so far its running great. Topped that off with a set of new plugs.
Tomorrow I'll finish pulling out the cowl vent to clean out the pine needles and other misc. crud and replace the seal. God I love that the weather is getting nice.
