59 F100 223, Holley 1904, new 240 duel advance points dizzy. Just put the dizzy on a couple days ago. I changed the carb base to one without the valve in it and today I plugged the venturi hole . It actually ran better before I plugged the hole, it wasn't great but now it is worse. Timing is set at 5*, new timing chain, compression is 135-150, new plugs ect. After I did the dizzy I drove it around my yard and just about couldn't get it up my steep drive way. Really thought going port vac was the answer. Tried manifold vac yesterday and the timing jumped to about 50*, backed it way back and it would not run right at all.
