It seems to have started whilst it was in storage over winter but I didn't
really twig to the problem until I had to top up its tank and found it
dripping continuously through the vent plug.
I guess I just need a new cap but any ideas as to why it should have started
leaking in the first place? There are no cracks and the O-ring is intact.
The fuel is definitely coming through the central breather plug.

If this is while it is in use....
Could it be the fuel which is being agitated to the point where it is
able to splash up and out of the vent. There should be some sort of
baffle to prevent this and encourage the fuel to drain back down into
the tank. Is the baffle missing?

No. I happens if I just tip the strimmer so that the fuel covers the filler
cap.
I had a quick google for McCulloch spares but could find filler caps.
Anyone know of a site selling filler caps?
Tim
In that case I would suspect the filler itself is not sealing properly,
I think the cap needs to seal to enable the breather to work as
designed. We had a plastic filler cap on a plastic tank (lawnmower).
The cap would tighten up, but binding on its threads due to distortion,
it would not screw down all the way to the O ring seal.
Nope. Please re-read.
