Carburettor Float drain screw.(solved)

[darrsi]

Well,

I've drained the carbs with great success, took the old girl out for a test ride of about 20 miles and not a single hiccup. Result.
Or so I thought.
Today on my way to work the problem has returned. Several times the engine RPM would just drop down slowly, regardless of the throttle position. Strangely though if I pull the clutch in, let the engine stall and blip the start button again it will fire up again. I could always change the plugs but I'm thinking this is possibly water/particles getting into the carbs.

Any thoughts?

Before changing the plugs, chop about 10mm off the ends of the HT leads, and rescrew them back in.
Better still, if you still have OEM spark plug caps on, replace them with NGK ones, a lot of us use them and they're dirt cheap in comparison to £200+ for OEM ones.
