Rob nailed it! Don is the guy. After talking with him all of my Mighty Demon issues disappered. I will never go back to Holley again. The engine runs with a nice curve and the idle is perfect. There is a lot more to tuning the carb than the corner screws. First I made sure the distributor was right. I sent it to Don to have it recurved. Secondly, made sure my spark was all it could be by adding an MSD high vibration coil along with my 6AL. Then I triple checked the timing with Don on the phone.
