I'm trying to repair a Model 20444. The left rear wheel will not roll backwards when clutch is disengaged. Tried replacing all the internal parts in the wheel mechanism but it didn't help.
I'm hoping hoping someone has run into this problem before.
There is a key under the small gear that appears to be there to engage/disengage the wheel from the axle, but it's not clear how it's supposed to work. It looks like the key is supposed to disengage if the gear/key/white plastic ring are not pressed together, but there is a spring that always presses on them.
