let joy be unconfined.........Not only did your the tip work Chris but the carburettor leak is solved also.The jolt of freeing up the clutch when I started the engine must have jolted the float which I guess was just sticking causing the float chamber to flood. I don't know the smiley equivelent of shaking someones hand but if we ever meet I owe you several beers.
The sliding pillar returns to the realms of the possible once more.
