The Johnson bar on my '62 M20C takes two hands to raise and lower the gear. the problem is with the block and release button. I can't do it smoothly with one hand but it takes a monumental effort with two hands to raise the gear. Needless to say having my hands off the yoke on departure is not ideal! Efforts to lower the gear are equally difficult. Just had it up on chocks, the gear tension is in spec. All agree it is the receiving block mounted under the panel (recently replaced with a new Lasar unit). The floor retainer is functioning fine. I have 500 hours in a '61 M20B and never had problems putting the gear up or down with one hand. It's grounded unless I want to fly it gear down.
