Big Yella problem

[Col Foster]

I'm having the same problem with my Australian delivered 15" Cimex. Doesn't matter how often I flush it through, I still get overflow from the reservoir.
I'm thinking of taking the head to bits to see what the problem is.
As for your solution feed tube being too short, the spares I bought from Tam at Steam master were 1 metre long (should be 1.2 metres)
