shimano hydro shifter problem

[markyboy]

I bought a near brand new set of dura ace 9120 hydro shifters on ebay and cant seem to push the fluid from the caliper to the shifter chamber it seems like it is blocked.
I have done the right shifter no probs but this one is just pressured when i push the syringe.
I have checked the hose which is brand new disconected from the shifter and the fluid passes through no problem,i have taken apart the bit where the fluid goes and blew some air through but it looks like its struggling,there are 3 tiny pin holes and one larger one but still nothing,also when i pull the brake leaver the plunger is pushing fluid out but cant get it to the top of the lever for bleeding.HELP

If the shifter is clamped on the bars, it may be clamped too tight. What I do is lightly clamp and bleed the brakes then tighten.

try adjustning on the pad contact screw, loosen it a bit, i have had a shifter that had a blockage until i adjusted a bit on that screw

Yes i sorted mine,i had to dismantle the shifter until i got into the fluid chamber and push a tiny wire in to the very tiny hole which the fluid passes through until it cleared what was ever in there.
All good now hope that helps.
