Engine Idle Speed ????
Looking through the Haynes manual,there seems to be a lot of different idle speed listed from 68 to 82,why is that?
Also what is the difference between Base idle & Curb idle.I need to set the timing on my auto 79,but would like to set the correct idle first.
Thanks Neil.

like Vetterodder says, turn the idle down as low as possible when setting the timing. Even with the vacuum hose blocked, its possible to get mechanical timing advance from the weights on top of the dist shaft if the idle is higher. The purpose for setting the idle real low is to insure there is no mechanical advance occuring when you take your reading.
