[QUOTE="Jackson LeBlanc, post: 438890, member: 21054"] Final update- sorry I haven’t been very vocal on here, I’ve been doing a lot of research and after a lot of frustration I’ve found the issue and fixed it. Part of the reason it wasn’t pulling vacuum was because the idle mixture screws were adjusted all wonky and that’s why the engine ran super rich. The other reason it wasn’t pulling vacuum was because the EGR valve was stuck open which created a huge vacuum leak. There was also an exhaust manifold leak. Once I adjusted the carb and addressed all the other problems, it worked again. Only God knows how it managed to work the first time before going bad again. [/QUOTE]
