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!

I think I would still try another float. If this is the plastic foam
ones they do get impregnated with gas and do not float high enough.
That was the way it was in my Corvette., I kept adjusting the float
level until there was nothing more to adjust. A tech at Rosenthal
Chevy was sitting on the curb eating his lunch and bet me if I put
that float on the ground and stepped on it gas would shoot out. I
bought a new one first, then I tried it. He was right.
He asked if I had been putting dry gas in the tank (alcohol). Yes I
had. That kills them according to him. The problem did start after I
had water in my gas but I did not make the connection because it took
a month or so to show up.
