'Fraid not. But first disable the fuel pump and run the engine till the
carbs empty, then reconnect the pump. The resulting rush of fuel through
the now wide-open valves can clear any debris that might be stuck in there.
But if the pump carries on clicking and fuel comes out immediately you will
have to remove them and the bottom cover to deal with the float and/or
valve. If, when reconnecting the pump, it fills the carbs and then stops
and doesn't overflow, but does so again in a few days, it could be dirty
fuel or again a bad valve. I'd replace (or fit) a fuel line filter, flush
it again, and see what happens. If it happens again it must be the valve.
The pump should click less than once every 30 secs with the ignition on but
the engine stopped. You will have to give the carbs some time to fill up
and overflow, maybe a minute or so, if there is just a very small weep from
the valve.
I recently went through this on the HIFs on the V8, changing the valve on
one that I had problems with a few years ago and had started doing it again.
It had no effect and when I took them off again I realised that the float
was half full of fuel but I couldn't find the source of the leak even by
squeezing or heating it. I replaced the float and left the new valve in,
and blow me if it didn't start leaking again a few weeks later. This time I
refitted the 'old' valve, which obviously hadn't been faulty, and since then
all has been well. The moral of the story being that even new parts may be
faulty from the outset, or fail soon after fitting.
