I couldn't take the decompressor apart but cleaned what I could with the air compressor, if I blow on the decompressor nozzle the valve is activated so it seems to be working. If the decompressor is not on the mower it pulls easily, as soon as that port is closed, the pull starter is hard to pull.
Just about ready to pull this apart for spare parts, if anyone in Melbourne reckons they can fix it, it's yours.
Mark could you elaborate on what you mean by closing under suction?
