I've got a super C and a super M and even though I have optimas on both of them those old starters still suck when they are cold. Mine almost always turn over on the first or second crank with the hand crank though. As long as the timing and distributer is set correctly and not by some shade tree, they will start right up no matter how cold it gets on the hand crank. Right after I rebuilt my super C engine though I messed up and timed it to the wrong mark on the flywheel. That starter handle got a piece of my leg real bad. I thought it had broke my knee it hit me so hard but I got lucky. The thing coughed over backwards on me.
