I think my 727 is fried. Now I'm at a crossroads...
The kit did include the mumbly peg, and I think I know why they call it that. I found myself mumbling curse words while I tried and tried to get the rooster comb installed and the ball shot across the shop. Finally I got it.
I assembled the drums and started to put the transmission back together, will finish tomorrow. Pulled an accumulator spring from a core 727 I have and cut down a piece of pipe to 5/8" for the blocker rod.
