This is Ron's '83 CJ7 258 BBD CARB and CHOKE (my neighbor, across the street), Mine is Now a HOLLEY 390 CFM, 4 barrel on my 258, 6 cylinder (so we cannot go by it!)
On Ron's, assuming its like yours
We will make a STONE COLD ADJUSTMENT on the choke
1st, Hold the throttle back (maybe a 1/4 of the way open) This may not be necessary on your configuration, I cannot see it, and it will not hurt to do it anyway!.........This will release the "warm-up steps" so that the choke linkage will not be binding while you move the choke plate (yet another possible adjustment on yours, that might have to be dealt with, so that the Jeep idles at a higher speed, while the choke is engaged at different openings) When it finally, is STEPPED DOWN and And the CHOKE IS COMPLETELY OFF, the Jeep should be at NORMAL IDLE!
2nd, Still, I have no hands on----so you will have to wing this one! (its EZ) I just don't remember which direction to go!
Disconnect the choke wire......but reconnect it, when we finish!
Twist the Black Cover (in pic, says "lean" on it) Twist it slightly both directions, find the direction that will allow this: We want to have the Choke Butterfly CLOSED (laying flat).............But BARELY.....Almost on the Verge of opening..................Doing this adjustment sometimes works the best, when its really cold!..............Older BBD carbs, have 3 screws that must be loosened 1st, Ron's has rivets, that will allow "movage" or "twistage" of the cover (the bi-metal spring is inside of it)
Reconnect the choke wire, this wire helps to warm up the Bi-Metal Spring, which will assist in pulling the choke into the open position as the Jeep warms up.
Provided everything is still in that "HAPPY WORLD" Condition of 1984.......We hope its somewhat close anyway!
I INSTALLED MANUALLY OPERATED CHOKES ON MINE....I LIKE TO BE IN CHARGE!...... I HAVE FOUND THAT THE AUTOMATIC CHOKE STAYS ON TOO LONG OR GETS STICKY SOMETIMES.
You just gotta get used to using it, and feathering it toward off, then off, as your engine reaches operating temperature. When its really warm out, "On" to crank up, then immediately off!
You will soon learn how your peaked out engine, has the need.....or not for some or no choke, just by the way it runs well or sluggish
On some of the later CJs the choke does not operate like the one in the pic, If yours is like the one in the pic, it can be done in 2 hours or less (less if you "Catch On" real quick!)
I can show you how to do it, and it perform as it should, without it binding and getting hung up, or operating "On Its Own"
