    A supercharged engine needs increased initial timing and less total timing than a naturally-aspirated engine. Boosted applications like a short, yet quick ignition advance curve. Ensure your ignition system is capable and your spark plug gaps aren't too wide. Try more accelerator pump if there isn't black smoke.
    May God's grace bless you in the Lord Jesus Christ.
