It's not a hard job to re-build the carb. I believe it's a Tillotson carb and it's a relatively simple design. The hard part will be finding the repair kit. IBoats goes back to 1954 for a 7.5hp but I'm not sure if it will work on a '53. I've done a search for the kit and didn't find one. Someone on this forum will help you locate the right kit.
