Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I recently recived this walk-behind mower from a neighhbor and, thanks to the info on the board, was able to get the engine running.  However, the RWD power drive doesn't work.

This mower has a cable-activated RWD transmission, which is supposed to pull a lever on the transmission to engage the power drive.  However, when I squeeze the control to engage the power drive, the lever on the transmission barely moves (i.e. the cable does not pull the lever enough to engage).  I can get the transmission to work by forcing the lever on the transmission to move with a screwdriver, so it is capable of working.  I have tried adjusting the trim dial for the cable housing without success.

Can anyone tell me:

1.  Are there any adjustments I can make on the transmission?

2.  Are there any replacement transmissions available?  I believe the Murray part no. is 071549

3.  Am I better off just taking off the pinion gears and using this as a push mower?

4.  Any other ideas?

I don't have the manuals, but I believe its a 1996 model.  Thanks in advance.
