We've been using the 122 as stress-reduction therapy. The combination of SU carbs and changes in humidity and temperature here in Florida has made for some near endless fiddling with the mixture and idle settings. Slowly, but surely, we are getting the old girl to pull from 1200 RPM all the way to 7000 without fuss, as well as idling …
To anyone who wants to avoid blenderizing your overdrive unit, add a relay activated by the reverse lamp switch that interrupts the overdrive circuit. Also be aware that the overdrive pump needs a minimum shaft speed to operate properly so avoid driving under 20 or 30 mph with O/D turned on.
I also added O/D on my 122 and noted it acts like it's slipping when I drive too slowly with it on.
Bring out your dead. I did enjoy the term blenderizing. Sounds like useful information.
