Ahhh, I found the problem, I looked in the mirror, I knew these had the adjustable brush but its been a long time since I've delt with it, I've had my late 31 pickup since the early 70's, its not on the road but does function, anyway I did pull one of my cores apart and then saw what the adj brush was all about, that is a tough object to try to explain to someone how to adjust its not really obvious how to move it, and somehow I thought there was a screw on the back side to loosen the holder, not the case. Now my pickup has the the gen with the arm screw close to the pully, here are pictures of the other two I have. The new cutout is the mechanical type not the junk, same as the old one.
I did move the brush and got the rate down, at hwy speed it is now in the rang of 8 to 10, Optima says somewhere around 6, in town it is in that range, I may lower it a bit more.
Thank you for all the help
