This is not a race vehicle by any means. Just trying to free up a little power, and clean up the engine bay. Pluged egr valves just aint pretty. I would like to keep the PCV to help keep the valve covers clean. I tried without once and just one trip down the road I was cleaning oil off the breathers and oil fill hole. Anyhow, Denny I got your point about setting idle mix with a gauge. The procedure is where I need help. Do I adjust the screws to achieve max vacuum? Do I check the vacuum at the manifold or the carb? Do this before or after setting the timing?

Techinspector,
I have no doubt in your experience and knowledge. Just a fun little s10 strickly for the street. Thanks for your suggestion.
