Spent a couple of days over the past couple of weekends working on the Wagoneer. Was nearly impossible to start, and wanted to stall as soon as I put it in gear. Multitude of issues, none major, but some a major PIA!
First, the rats nest of vacuum lines. Armed with spools of vacuum hose, I replaced all of the dried out, cracked 40+ year old vacuum lines. There is a special place in the hottest bowels of he** for the engineers who designed this mess! The videos by Dr. Bob's Last Chance Garage on YouTube were a lifesaver! While I was there, I also replaced the blown out EGR valve, PCV valve (unique hose arrangement required some creativity), and repaired one of the choke heater tubes.
Next up was the carb. I rebuilt the carb when we bought the Jeep, but did not mess much with the overall adjustments. Adjusted the choke and fast idle, and checked everything else while I had the carb off the Jeep (made doing the vacuum lines and EGR valve a little easier with the carb out of the way). Once again, Dr. Bob's videos were extremely helpful!
Threw on a new cap, rotor and wires (ran out of time for the plugs, it was already approaching midnight at this point). Cranked it over a few times until I got fuel coming out of the line, hooked the fuel up and it fired right off. Much smoother idle without countless vacuum leaks!
First opportunity I've had to work on the Jeep all year, thankfully it was a success!
