258 dies under initial load
My new to me 77 CJ7 AMC 258 i6 / 4.2l I6 with 1bbl Carter carb is behaving badly first thing in the morning. It starts fine - I had the air cleaner off to watch the electric choke do it's thing. Idles great, I can goose the throttle and it will stay lit.
I back out of the driveway and roll down a short hill to an intersection where I have to turn left and head up a hill. Half way through the intersection, the motor conks out.
Restart is nearly impossible. Today, I took off the air cleaner and found the choke mostly open, not all the way, but 3/4 probably. It cranks great and stumbles when I let off the key.
Once I get it running, I can get up the hill by over powering it - 3000 rpm or more. The next mile or so is flat and it runs just fine. The engine is fully hot by the time I get to the next big hill and it goes just great.
My initial thoughts were a stuck or broken electric choke, but it appears to be doing ok. Now I am thinking fuel delivery (filter, pump, lines, sump screen) or sunk float.
What do yall think?
