Long tine lurker first time to post (JK ). All seriousness...bought this 85 60 last summer. It’s 100 % bone stock and has 140ish in all cylinders. One thing I’m not is a mechanic. I have a few resources and have built some motors, but diognosing engine performance is not my specialty. Plan to keep this motor smogged so I can register it at our place in CO. The truck sat for 5 years prior to picking it up in June. Put in a clean used tank (blew out the lines), new filter, a new JimC carb (1000 Miles) that I took off another truck, JB welded some pinholes in the air rail, replaced many stiff/questionable vacuum lines, put in a used distributor with a working vacuum advance, new cap/rotor and a used catalytic converter out of a parts truck. No guarantee the converter is working well but it’s not all crusty like the other one. Attached is a video of the vacuum. Would like some feedback on where it’s sitting. When cold the motor has a serious hesitation. Goes away for the most part once warm. I did adjust the valves as well as advanced the timing so it would stop backfiring. It’s set well past the 7 (I believe that’s the #) degree mark recommended in the FSM. Also, I ran it for about 20 min and temps hold well etc. but the exhaust smells really bad like trucks I’ve had that were desmogged with the catalytic converter removed. I welcome any thoughts/suggestions as I have zero experience with smogged systems. Thanks. Jimmy
