PV doesn't function at idle.

By Gerry Proctor - 03/03/2005 3:30:38 PM; IP 207.133.188.254

The idle circuit and the power valve (main metering) are in different circuits. If you have an otherwise properly functioning carburetor, you can take the power valve completely out, start the car and let it idle. There will be no difference.

The only way a PV will affect idle is if your idle is way too high and you are well into the transition circuit.

I'd look for some debris in the idle airbleeds.

Symptoms of a blown power valve are a very rich cruise mixture.

A 6.5 is a good choice for most streeable apps, if you are going to replace it.

This thread, so far...
