A complete and proper rebuild is not difficult. Make sure you get a quality kit like the Keyster. I used a Hygrade kit that included the diaphragms. There is a guy on you tube that walks you through he process if you don't have a manual. I can't remember his name, I'm sure someone else does.OK here's follow up...put tracer in bowl and checked with UV light. I couldn't see where fuel was leaking. Anyway while I had it opened up decided to try "Oklahoma rebuild." Well that didn't go very well at all. At first would idle OK but stumble coming off idle during acceleration. That problem went away and now can't get it to idle...starts fine with choke, runs fine at higher RPM, but when goes to idle misfires and then dies. Pull the choke out just a little and it runs fine again. Idle circuit maybe? Anyway, to clean it without removing carb?
Cruiser Outfitters sells these.Make sure you get a quality kit like the Keyster.

So, how does the float bowl get emptied in your scenario?The solution is between the carburetor and the tank, I'm guessing the seal in the fuel line is broken, allowing back draining to pump/tank circuit. It may be sealing under pressure, becoming a vent when pressure is taken off.
