Try what Cobred suggests. If the primaries are spraying, then it's most likely a spark and/or timing issue. If not, then you have a carb issue and should look on the Holley site for help. I have the same MSD set-up and Holley... couple pumps on the throttle and blam, she's fired up. You can try the sock in the carb to simulate a choke, but with 75 degree temp it shouldn't be necessary. By the way.... that starter fluid will light up by rubbing a couple of sticks together
