Hey folks, need some help with a Jeep CJ - ideas or if you want to help wrench on it... i'm in Greensburg PA - here's what i've got
77 Jeep CJ7 258 I6, MC2100 carb, HEI ignition, 5 speed
CJ idles rough and stalls when hot. Choke is operating properly - fires right up when cold, idles pretty well but not quite smooth - gets hot and idles rough.. stumbles and stalls if i try to put it in gear and move
New carb MC2100 - thermal choke - ran fine for a few weeks.
new fuel pump
checked fuel
checked fuel filter
checked time (as best as i could)
swapped ignition coil, checked wiring, plug wires all seem cool, cap n rotor look good
plugged off all the emissions components one by one to eliminate
re-torqued manifolds and carb base- I'm still thinking vacuum leak is the problem - i see a lot of discoloration around the gaskets:
If i close the choke manually the idle picks up and the jeep runs great. under wide open throttle the jeep runs great - let it off and it pukes. I ran starting fluid around the manifolds as well as a stethescope but i can't really discern anything...just a bit if anything..
Anything any of you see that I missed? Anyone familiar with CJ's or know anyone in the Greensburg area that would be good to get a hold of?
