1 I have the edelbrock performer intake. It is a split divide at top. Which is the correct gasket. 2i have a 1973 qjet. W divorced choke. Rod n spring. Is there an electric choke upgrade? 3 has anyone had to add a washer to the primary throttle plate screw so the spring does not bounce around loose. I had the qjet built then repaired. It’s working better and will get back to it tomorrow. 14* timing 33 total w mad distributor. It runs rough at idle but about 11” vacuum. Needs moves around a bit. I might add some questions tomorrow when working on it. Thank you.
