I'm losing my mind. Bought this jeep a month ago. Installed hei distributor, weber 32 36 carb, Timing chain, rear main seal plugs wires and once it warms up it dies at idle. Fires back up then dies. I put a fuel regulator on and new fuel filter. Removed a few vacuum lines (maybe too many). Now 4 wheel drive doesn't engage (head slap). Taking to jeep west tomorrow.
