Hello everyone .. Beautiful day out today .. was wondering what the carb settings were for a 1986 f250 5.8 was .. (351 Windsor) .. The carb is motor craft 2 bbl but the Tag is gone so I have no # for it .. When I start it to warm up for a bit it makes a loud thumping noise out of the exhaust .. I haven't done a tune up on it yet .. Also to mention it has straight pipe (No muffler .. .. LOUD ..!!!!!.. LOL ..) For now anyway .. Just wanting to get Her road ready .. Cant wait to enjoy the warm weather for some country cruising and Snapper fishing .. Thanks for any advice .. Take care ..
