correct, but you can be at TDC on the exhaust stroke with the balancer at 0*. pull spark plug one and crank it over by hand. as the balancer approaches 0*, have your finger in the plug hole and feel for air whooshing out. if you feel air, stop at 0*. you are at TDC on the compression stroke. if you dont feel air whoosh past your finger or it is feable, rotate again till you get the whoosh.
good luck.

Also, on the compression stroke, the rotor will be pointing at the #1 cylinder terminal.
