Chuck , I think you must have a different engine than the ones I have . Looking at the engine from the front the notch should be from 6 o,clock to about 10. This engine you can't rotate the cover as it has a cut out at the top for piston clearance ,(in the picture under the "bulls eye") . With the timer arm screws in the right places you will only be able to move the arm so far before they hit the cover webs . With the side timer arm ,fully retarded it will be almost straight down & fully advanced at about 9:30 . The longer screw on the side of the long part of the arm will set that . Easy . MAX H. :D
