Hey, that's looking great! I did my carbs five years ago when I first bought her. Tried the Keyster kits but ended up stripping them out for Randakk's o-rings and lurking eBay for the float valves. I did my leak testing with isopropyl alcohol and a Mighty Vac. This was because our garage is in the basement and my wife is sensitive to gas fumes. Glad I did, because they came apart several times to correct things.
