There is where the problem lies. What is a light pass? It could mean this amount to you and that amount to someone else.
And this scenario is often the case. It fires and wants to run but just doesn't quite do it so just a little more will surely make this ole girl go. That made her sound like she may mean business so lay down on that squirter and the next thing we know the plugs are screwed up and back to square 1.
Thanks but no thanks, I'll stay with my gasoline priming.
