My Monarch with the 6-1/2 HP HFT engine wasn't shifting out of low. Today I pulled the Sturmey-Archer 3 speed tranny jackshaft and opened it up. Gee- It's been years since I did that. I was reallly lost for a time, but I opened up a 2nd one to see if it was any better and couldn't see anything wrong but rust. I soaked the parts in hot water with dishwasher soap and followed with lots of phosphoric acid and finally WD-40 and oil. Re-greased the bearings and re-installed. Finally I discovered the shifter lever isn't doing it's thing. I guess I need to find another one. Tempted to go with a twist grip shift if I can find one. G.Oskar in Tulsa has lots of old crap. Will check tomorrow.
