When ever we run NSS we switch carbs over the Edelbrock 800 1412. When we do this it has a bog right after the hit car initially goes then bogs the is fine. Bad thing is bog is not consistent. One pass its okay we can live with that to old $h!t we lost a tenth in 60 foot. Talking to guys this weekend at the Northern Class National they said drill the secondary weight. Well where do I drill? I know I need to keep track of how much I drill incase it doesn't help so I can add weight back. And help is great.
