318 TDC help

Got a new distributor for the 318, current dist timing is no good. Is there any way to find tdc in a 318 by just using the crank dampener and the rotor button location? On my crank dampener i have 2 sets of 2 yellow lines, one goes all the way across the dampener edge, the other set only goes halfway across the edge or so, dunno if that is by design or wear, also dont know if they have different meanings. What i've been told is that the 2 yellows going all the way across mean tdc on piston #1, just dont have anybody around atm to bump the starter around to compression stroke then hand crank to the lines, hence the rotor button question lol. TIA
