Sorry I left out a bit of info. Mine is a 52 with a 56 235 in it. No there is not an opening above the starter. It under the starter, whitch makes timing it dicey. To see the bb and pointer you must stick your upper body between the inner fender, motor, and fan blade just to see the the opening. The old girl runs well, and I timed her with other means. It just seems to me that something isn't kosher if you know what I mean. Jimmie.
