I saw washable ones in more reasonable thicknesses - maybe 2, 3 and 4 inches? Can't say for sure where they were, maybe Barry. I'm still trying to find booster and jet info. Not much help here and only crickets on Ed's site. I'd start buying books, but don't know which ones to buy. Maybe tuning schmuning is the way to go.
Hope it runs and drives good. Don't forget about the burnout video.
