Sounds fine so far. Now that the RPM has increased,
go back to the front carb (nearest radiator) and back
off the idle adjust screw (#3) just a touch. do the
same w back carb until you are under 1000 RPM's. It
will probably never be super smooth at 600, so don't
obsess, but it should run withour jumping around at
700-800 and you'll be close enough. YMMV
