until you find the actual TDC you will never get this thing to start, or run properly. You also need to verify that the spark is actually occuring at the correct time, having the rotor pointing somewhere in the vicinity of the #1 spark plug contact isn't adequate. You were told at least twice how to make an extremely simple TDC checking device. As well as how to use it. Now you are just wasting time, yours and ours. But it seems like you have the timing to far advanced. And the mechanical issue is probably you dont' have the timing set correctly.
