You should make sure that the jets are centered (i.e. the needles are not
binding in the jets when the piston is all the way down) and
that there is no damage to the piston chambers, or junk inside the
piston chambers, that could be causing the pistons to bind.
When the engine off, push the pistons up with your fingers and watch them drop.
They should both feel the same.

Also make sure that the springs inside the piston chambers are correct and 
matched.
