Not so, but close GM had a .060 plug gap for a long time but after B
P said they would pay for any toes caused by fuel line freeze up
and GM had a lot of no starts in cold weather that changed things to .045 gap and the cold start problem went away.
Yes sir. GM used .060, then .080 and finally .120. I was there, on the line working live and in person everyday. They were trying to experiment with emissions control.
