I'm beginning to prepare my dad's Cobra (recently inherited) for the summer driving season. The problem is that this is the first carbureted car I have ever worked on. To make matters worse, I will have to get emissions testing early in the driving season.
He always had to tweak his setup for emissions and then return it to normal after the car passed. He wrote down the changes he made last year to get under the regulations. Among other things, they include increasing idle speed and running on 25% alcohol (with 91 octane). Any reading that would prep me for the work required to make the proper adjustments?
I've started reading "Super Tuning and Modifying Holley Carburetors" by Dave Emanuel since I found it lying around my dad's garage but the reading makes me think that it will take experience on top of the book smarts to get things right, and I don't have any carbureted cars to practice on.
Beyond the idle speed adjustment, what needs to be done to run on 25% alcohol? How difficult is the work? Any adjustments that could really foul things up if done incorrectly (if not I can just practice on the Cobra)?
Its a Holley carb but I don't have the model off hand (I can get it if its important). And its on a 427 side oiler.
Thanks to anybody who takes the time to read this ridiculously long post
