Timer Roller

When I installed my roller I noticed it could be installed two ways. I found a notch on the end of the shaft and used that to install the roller. My car (hand crank 1915) starts best with the spark advance at 1/2 quadrant not fully retarded as most. This is where it runs best on magneto also. Could the roller be 180 off?
 
I'm not sure I'm following your description. The way to install the roller is to line up the notch on the edge of the roller collar (that slips over the camshaft) with a little hole in the camshaft, and then a small pin is inserted to hold it all aligned. A ring then goes over the camshaft that covers the pin to keep it from falling out, and the nut holds that and the roller on.The pin alignment ensures that the timing is correct. What do mean by a notch on the end of the shaft?

PS I doubt that the roller could be 180 degrees off as the car wouldn't run, unless you've moved the wires on the commutator body around to compensate.
 
A lot of camshafts had that hole for the pin drilled through the shaft making 180 timing off a possibility. I cant seem to do the math, but the crank spins 2:1 of the cam meaning the roller is really only out 90 or 45 degrees which is like half the quadrant. ws
 
It sound like Ken has the wires installed on the timer one stud too far clock wise (looking at the timer front).
