Help wanted with the Carter/Weber progressive 2bbl carbs from langdon Stovebolt on an offenhauser dual carb (2 x 1bbl) manifold. Do they work out of the box? jetting changes? I know this HAS been done before as stated here - but nobody said what was really needed to get them working. They have electric chokes - I despise electric chokes so hopefully can convert to t manual - but as-is - do they need to be re-jetted for use on a 225 with mild cam, ported head and headers? I have the 2bbl/1bbl adapter pair - but think just machining the manifold for the 2bbl carbs and installing new studs will be easier - some carb heat will be provided and there is more under-hood clearance. As it sits now - I have both this dual carb setup AND a 390cfm Holley re-jetted and ready to go on an Offenhauser 4bbl manifold. The 4bbl setup works - have used it twice before - but would really like the look of 2 carbs.
