Power Valve Plug??
Thought I would move this issue over to the carb section of the forum....
Trying to get to the bottom of some performance bugs on the combo....one of which is a poor idle. Doing the standard stuff in testing out the entire ignition system....checking for vacuum leaks around the intake...etc.
Finally moved on to the carb as some possible issues.....one thought was a blown power valve....but upon inspection I found that there was no valve only the Holley plug for the valve.....so obviously not a blown PV issue.
But what the heck is the reasoning behind plugging the power valve??....I suspect for racing application....but I want to understand how adjustments are made to increase fuel flow when needed apart from the job the PV would of been doing.
Thought??
And thanks!
