OK I have to take back some on my previous post because they were incorrect I did some more investigation today found out my fuel pressure at carburetor is one and a half pounds my vacuum gauge was not Sarah without broken got a new one not pulling 22 inches of vacuum pulling only 15 I’m going to first take care of the fuel pressure then I’ll take care of the power valve. So I just finished new fuel pump mechanical runs between 4 and 5 at idle. did change power valve to 7.5 per 15 in of vacuum but still has same thing same spot. So I guess I'm forced to look at power valve restrictor hole or channel?
