Timing and TDC

I pulled of my pulleys today because I am positive that I have set my timing wrong.

Well after some searching, I found out that the 12a and the 13b pulleys are different, the 12a pulley will go on anyway, and the 13b will only go one one way.

Well i didnt get any pulleys when I got my 13b, so I filed one of the holes to fit. Now the car wont start so I know my timing is horribly off.

How can I find top dead center? I thought that the little drilled dot on the pulley hub was TDC but I am wrong. Tried it today and no start. I also tried the method of looking at the apex seal through the spark plug holes, and that didnt work either.

The last idea saw si to pull off the pulley hub and align the key to the 9 o'clock position and 12 o clock would be TDC.

Well I dont imagine that I could remove the front fub without removing my radiator, I would need to get an air gun to get teh thing off.

Now I just thought of something, could I put the car into gear so the engine will not move easily and then use a socket wrench to get it off?

But anyway what is the correct method to find TDC?

Go in my profile and look at my last few posts. I just asked a similar question not too long ago.
