Yes and no. Depends upon what your ignition is set at.
If it is set ATDC, then yes, if BTDC, no. Basically
when looking from the 'ignition' side of the engine,
the crankshaft pulley rotates towards you. With a
strobe timing light, retarding the ignition will make
the timing dot on the crank pulley move away from you,
and advancing it will make it come towards you. TDC is
just a reference point stating that number one
cylinder is at top dead centre
