Obtained a mint condition 1974 Mav, 4dr, 250, 31k Runs poorly, appears to be carburator issues, I sprayed for vacuum which resulted in me replacing all gaskets from manifold up, including spacer plate. Didnt fix anything when I spray around the same area it still affects the running condition, any suggestions. Ive replaced all standard tune-up parts. Picture comming soon jay
Welcome from Florida! Jay you might look for a vacuum line to be loose, missing or having a split or hole in it if you have not done that yet. Spray in small areas in short bursts to try and isolate the leak. Good Luck
