You getting pops?
May be 180 degrees out
We had to take an old dizzy cap and cut out the center so we could actually see where the rotor was pointing
Then we lined up the timing mark on the crank pulley at 0
Looked thru the hole in the cap to make sure rotor was pointing at #1 when the dizzy was seated in
Sometimes you have to have someone turn the dizzy back and forth slowly when cranking to get it to crank
Its off more than you think
Then i set the timing. By ear listening for knock going up a hill full throttle or with a vacuum gauge
