My 1972 140 h1 transmission goes forward and reverse fine, but if I go forward and want to maintain that speed, I have to continualy push the lever to my desired speed as it creeps back towards the neutral position in a short period of time.
Roy,
I had the same problem on my 140. I tried the friction adjustment which Ron mentioned, and it helped some. The full cure was the procedure outlined in the service manual, which basically involves centering the cam located on the side of the pump. If you can pick up a service manual it will help a lot.
