The Ford Barn

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.

Make sure the wire pigtail is dressed properly, it can only go one way or it will intermittently short. Be very aware of the assembly hardware too, the wrong order can cause problems.
