I agree, Jim.In 81 Cutlass's attached link, Texas T replied. He's a member here as well. He rarely visits though. He is a very knowledgeable 200-4R guy, that helped me a bunch when I 1st started messing with a stock one.
The governor is an easy component to remove and work on. I'm not one to complete a full tear down, but getting the governor outt is as easy as changing the oil and oil filter. Just need to source the governor housing gasket in case the old one tears when disassembled.
Rich has always been helpful when it comes to 200-4R knowledge. and doesn't mind sharing what he knows.
