First set your timing to what the book says around 10 before top dead center (the vac advance line should be disconnected at the distributor then pluged) then like johnny says turn in the 2 front mixture screws untill seated use fingers only. Then with a screwdriver back out each mixture screw 1 and a half turns. Adjust idle speed screw to book value around 650 to 700 rpm stay away from the secondary valves and choke adjusting screws. If you have the external adj. points on the distributor using a allen wrench screw clockwise untill engine misses then back out till miss goes away, check idle speed and timing again, unplug vac. line a put back on distributor. Then using your timing light check to see if you have vac. advance. Its been a while since I did this but it should work.Mike

fredneck you can do it by ear. Get in car and put it in drive when you take foot off brake it should feel like it wants to creep forward, rpm will now be around 400 to 450rpm. When adjusting idle speed make sure vac line is connected to distributor. To check for vacuum advance with engine running pinch and disconnect vacuum line at distributor the rpm should drop. To review (trans. in neutral adjust idle speed screw for around 700rpm)(trans in drive 400 to 450). I dont like to adj. rpm with trans. in drive without someone holding the brake down. Mike
