Suzuki GS850 Chop TLC Part 3 - Timing & Start Up

So today I've managed to get the timing advance finished off and gave the carbs a very quick clean, chucked some fuel in and turned the key... Very happy she started on the button but now I have to do a card refurb as they're leaking a bit. I suspect the float valves are gummed up and not seating correctly so I'll order some new ones and see how I get on with those.
