I recently removed the upper plate to replace the wire and adjusted points/timing per Marco's page. I think the timing is too advanced - when I pull the spark control lever down past 1/2 way, the engine begins to misfire. I have re-timed it three times - with the same results. I'd like to loosen the cam and turn it ever so slightly to retard the timing and see if this makes a difference.

I know it's not the correct way, but I'd like to see if my theory is correct.
The rotor turns counterclockwise, so turning the cam clockwise will RETARD the timing.

Make sure the wire terminal between the plates is bent against the points mounting nut, so it won't touch the spring or distributor cast body as the advance lever is moved.
