One of the most common issues we see at my classic car repair and restoration shop is a car that is idling rough.
One of the prime yet overlooked causes of a rough idle is the power valve on the carburetor.
We made a video about rough idling and the power valve.
In this short video, you will learn:
- How to tell if carburetor is getting too much fuel (running rich)
- What a power valve is, what it does, and where it is at on a carburetor
- How the power valve impacts the idle
- How to tell if the power valve is bad and how to fix it
