Harms Rebuilt '71 Thermoquad - Wondering Idle, Stalls when Put in Gear

How many miles on engine. Cam walking from loose timing chain, vacuums leaks, base gasket leaking. Lots of stuff could be going on but carb may have gotten a small bit of junk or maybe those epoxied pots at the bottom broke loose. Hard to fix over internet. Lots of questions.
Unknown mileage on engine but doesn't smoke or behave like a high mileage motor. All vacuum access points were plugged when I was tuning carb and engine ran essentially the same with everything hooked up. I suppose I should pull the carb and check the pods.
