Issues with a rebuilt 360

Just an FYI. Setting power valve opening by using half idle vacuum is not the correct way to do it.

Also, the power valve can be open at idle and it will not affect the A/F ratio. I’ll go and see if I can find the video that proves that.

Well changed it and no more black pipes or watering eyes and it will actually idle now below 1300 rpm. So unless I tightened up a loose gasket or jet or something
