225 Slant, Holley 1920 base tune?

@RustyRatRod Help a brother out! Screw idle in to seat and then out 1.5 turns. Start with that. loosen idle screw and turn it in just to crack it. Does your 1920 still have a working choke? It should light off in under a revolution with some fuel in the bowl. Before you do all that, check your valve lash, I .011/ E .021 cold should get you running. Also check your exhaust heat riser valve, see if it actually still moves....if its really stiff, make it stiff in the open position, ie rotated off the stop. THat wont stop your car running but it will make it run better when warmed up. Those 1920's can get gummed up in the valve body in the fuel bowl. Have you tried to clean it yet? Once they are set up, they really do run like a sewing machine.
