Well I've owned it for a year now, a 58 biscayne auto 235. bought it for 2500, with 47k miles, it ran halfway good but needed help. tore it down this winter and gave it a head job, and purchased a offenhauser intake with 2 carter carbs, I just got everything back together and there is one problem, I can get it to start but it idles at like 3k, I cant seem to get these darn carter carbs to work right, any help, anyone?
