The picture on the bottom left shows how the float adjustment is done on my carb floats. Mine are
the PHF 30's with connected floats.

But, the 18mm adjustment did not have the floats coming high enough in the bowl to shut off the fuel
flow. I bent the damn floats down to about the PHBL settings (24-25mm). Now the floats are pushing
the needle up enough to shut off the fuel flow.

Sure wish I had Harry's Ducati to contend with. Just think - if it's never ridden, it won't ever
have a problem!
