So the re positioning of the lever on the spline doesn't work - as the outer spring steel release fouls on the locking mechanism.
I had the piston out but couldn't budge the piston on the shaft. (Maybe need a bigger C spanner)
However the bottom of the piston seems perfectly aligned with bottom of cylinder when assembled.
One would assume that is screwed home fully and tight, so i don't see what adjustment can be found there.
On the very top of the group i have an acorn nut - no spacers or anything underneath.
Short of different seals, wheat should i try next?
Should i be using a c spanner on piston and spanner on top nut to undo assembly?
Kitt you suggested spacing the upper assembly - i assume you managed to get a shim the whole circumference of the group head? As i don't see any satisfactory way of raising it.
Spot on regarding the type of group - it is the same as this....Visacrem lever rebuild
