    Default Rough idle and hard to start Blown Alky Pro CDI 600.

    Engine wants to surge at idle, and is hard to start. Kills plugs #1 & #2 on 2-Step after one second. Not sure what I'm missing. Thanks, Jim

    ...and is hard to start.
    If you take the time to study this, you'll be a startup tuning expert, and read the "TIP" in post #6:

    Kills plugs #1 & #2 on 2-Step after one second.
    Holley EFI goes into Open Loop (no Learning) during the 2-Step Rev Limiter activation, so ensure the Base Fuel Table is well tuned in that area.
    May God's grace bless you in the Lord Jesus Christ.
