Most likely cause of jamming is burred first tooth on the starter quadrant .......first meshing tooth should have a sharp point .....when it gets burred ,the traditional cure was to grind it off and sharpen the next tooth...........ditto the mainshaft ratchet gear ...it should have pointed teeth ..........I d also add ,you never stab at the pedal,mesh the gears first before applying pressure ...........The 1956 on AMC box has the Norton style kickstart with a sprag engaging an internal rack ......reliable and near abuse proof.
