The Ford Barn

Just recently changed the spark plugs and wires in my 36 ford (with the help of some of my barners). It was backfiring and losing power and i noticed some of my plugs were fouled. Now it isn't backfiring and it doesn't seem to lose power, but it seems like it is "jerking" and not riding as smooth. Maybe a loose connection or something? Thoughts?

Maybe the timing is to far advanced. A flathead will jerk at low speed in high gear if it has too much advance, good luck, Chuck.

make sure you didn,t mix the wires. start the eng short each plug one at a time. if wires are crossed you will notice no difference in eng idle when you short the mixed wires.
