Is this a joke question? For real? The balancer is pretty much already marked. Honestly. Use your head for something besides a hat rack.
Bring the mark on the balancer up to the zero on the timing gauge on the timing cover. The cover should have 10* after TDC, zero and 10* before TDC. Simply transfer the 10* before TDC marks from the timing gauge on the cover to the balancer with the balancer mark lined up on zero. Turn the engine so the zero mark on the balancer is lined up with the 10* after TDC and mark the balancer again lined up with the 10* before mark. Keep doing this until you can read 60* BTDC worth of marks on the balancer.
Just because something costs 100 bucks, doesn't mean it's good. I would send that junk *** light right on back.
