Yes, they're all like that. When the hole is aligned with the pointer, the
belt doesn't cover it.
The hole marks TDC, not the 4 BTDC that the engine is supposed to be timed
to.
BTW, a timing light may not be accurate on a stock engine, as the
centrifugal advance may be active at idle rpm. Static, or "road test" works
better. The book method is to static time to TDC, then advance 4 degrees
using the vernier on the dizzy, then road test for final adjustment.
