I heard it crank up today! :happydance:
Since the engine has been sitting 20+ years I tried to do a little prep before trying to crank it for the first time. Oil change, checked the rotor/cap (they looked great), checked the plugs (they looked great), squirted a little oil on top of the cylinders, and ran a hose from the fuel pump into some fresh gas.
I pumped the pedal to set the choke and poured a little gas into the carb. It fired up immediately! It didn't even turn over once before it sprang to life and roared until all the fuel I poured in the carb was burned off. I repeated this three more times trying to let the fuel pump prime itself but it never could run on its own.
I pulled the fuel line off between the pump and the filter and it was bone dry. So maybe that's why they quit driving the old Jeep. Fuel pump died.
I went to the local parts store to get a new fuel pump and when I said '81 Jeep Cherokee' all three guys working the counter had stories to tell.
By the time I got out of the parts store it was getting dark.
I'll have to wait until tomorrow to get the fuel pump put on (no garage). I'm so excited!
