Default G9 cam, crank, counter balance alignment

I replaced the rings and crankshaft seals on my 1991 G9 and according to my book there should be a mark on the crankshaft to align with the hole in the cam wheel which worked out fine. It also shows "marks" to align the crankshaft counter balance, but the crankshaft has only what looks like two barely discernible hand made figures on two of the teeth.

The cam lines up fine with the crank but when I next turn the crank marks to align with the counter balance, the counter balance jams. If I eyeball the counter balance to align with the crank, it works fine but the marks on the crank are about 30 degrees away from the mark on the counter balance.

Sorry, I don't have pictures but those hand made marks are really hard to see. Does anyone have any suggestions on how to deal with this?

The engine is all assembled and the cam timing is fine for TDC and rotates smoothly, so I am considering to go ahead and install it, and try running it.
