New here with carb / stalling issues
Been a few years due to health issues my 1970 Dodge Dart Swinger 340 A727 has been on the road. No work done on it except for periodic start ups over the years. Had the car since new and I always had the skills to fix any problems. Age has set in and can't figure a few issues out. Old school way of checking for vacuum leaks is spraying carb cleaner around the carb and listen for any idle change. When I spray it around the shaft with the vacuum secondary lever (see picture) the idle drops and almost stalls out. No other idle changes, all lines are good. The carb (Holley 0-80454) was put on either late 90's or very early 2000's. The car has been off the road from shows or cruise-ins since 2008. Last driven 2018 back from a garage and parked. Question is could that rod/lever cause a vacuum problem? Also it will idle, some rough and backfires on a rev past 2000rpm. Also when running it stalls in gear. Was changed over to Direct Connection Electronic Ign over 30 years back and ran great. Trans is A-727. Stock numbers matching vehicle. Only other mod to the motor was replacing the cast iron manifold with the Edlebrock LD-340 in 1972. Any help would be appreciated before I have to trailor it to a shop to get it back running. Plus where we leave there are not many if any shops with guys who know how to work on muscle cars. Thanks.
