Hi Dane,
Have the carbs been rebuilt or cleaned recently? There's not much of a
float needle on these and crud can easily make them stick open. You can
remove the top of the float bowl by removing the fuel hose, loosening
the 8mm locking bolt and then unscrewing the top (gently). At that point
you'll be able to check to see if the floats move up and down freely. If
not, you'll probably want to remove the float bowl from the main carb
body and clean them thoroughly. It could be that the brass floats are
leaking (fuel gets inside them and makes them heavier) and will not shut
off the fuel flow properly. Might want to shake them and see if you can
detect any fuel sloshing around inside. More accurate would be to weigh
them (can't remember right off hand what the correct weight is). Boths
bikes with the SS1 carbs that I've worked on each had one of the above
problems. V700 - gummy needles, Falcone - leaky float. Both now run very
well.

Bikes with these carbs also have an "air lever" rather than a choke or
enricher lever. If I remember correctly, pulling the lever towards you
"closes the air" enriching the mixture and pushing it forward to the
stop opens it leaning the mixture. Confused yet? I am! Patrick Hayes
help! In other words, make sure the "choke" isn't on.

Not many Loopers like and use these carbs, they're known leakers (fire!)
even when set up correctly. I prefer the VHB 29s to the SS1s myself.

That's all I can think of right now. Cheers,
