ARCOR is an oval based organisation.... all 19 turns have to be adjustable timing...
all ROAR oval racing 19 turn motors MUST be adjustable timing...
for sedans, i belive you have to run locked endbell 19 turns... if the rule is still this way it is dumb.. you should not have two seperate 19 turn rules..
