The best way to confirm the timing mark on the balancer is to buy a piston stop and screw it into the #1 spark plug hole. Slowly rotate the engine over until you touch the piston to the piston stop. Then mark it using the timing tab as a reference. Then rotate the engine the other way until the piston touches the piston stop and mark it. In the middle of those two marks will be top dead center. Then go from there adjusting the timing.
