and this is how I have to set it for my engine to run good. I dont understand why I have to advance it so much, if I put it back to the original setting the engine pings and when the A/C comes on my idle goes up and down. I dont know exactly what my timing is set to but its all the way forward and it runs good, I feed it 89 octane gas. why is my engine like this ??????? I had to do this one day after " my intake got louder thread" that I posted--help me ???
