correct me if im wrong, but there isnt much need to check timing with a light if ive already confirmed TDC right?

check engine light: I couldnt tell ya; ive never had it running. all lights come on when key is in on position.

something I didnt note: the plugs I used are bosch supers, they are copper core which means less resistance in the plug. the old plugs looked to me like platinum plugs, but none were fouled out when I replaced them.
