Are you using "Household" tune-up gauges and equipment to Tweak your carb?
Do you have that kind of necessary stuff? (I have a suggestion, if you do not)
Pumping the pedal is not an uncommon thing on a carburetor equipped vehicle.I seldom use my Manual choke, on my CJ5, 3 pumps on the pedal and putter around till I get warmed up good. Or I'll go 1/2 choke (for better cold performance) until I get to operating temp.
I prefer a properly installed manual choke over automatic, I know when it's off or on, and can decide when it's time to cut it off (not prolonged, as with an auto choke) It's EZ to test for correct operation going down the road.
I do not "Depend On Correct Performance" until I'm at operating temp. Like jumping into traffic! Otherwise, Mr. Jeep might "hiccup", when I need power the most!
Do you know how to properly adjust an automatic choke and it's steps. Just fiddling with it, may not insure it works as it should!
Has anyone disassembled your carb, and changed the innards?
How long has this carb been operating without being rebuilt? (Time/ miles)
Sounds like you need to do a FULL SCALE TUNE-UP!
You might also check all of your VACUUM LINES/ AND VACUUM OPERATED GOODIES, FOR LEAKS. Including the torque on your intake bolts and hold-down nuts, carb to intake. And the screws that hold the carb together.
Are you capable of doing all of this yourself, or do you need a On-line helper(s)?
I have a 258 in my CJ5, it's not much different than yours.I have some homemade pics that may, help, if they are needed, as we (may) continue to get you to assist you.
If you'll do all of the labor, and keep up, we'll "Straw-boss" you, thru the process!
Your turn. We can keep this going forever, if you are game!
. Someone please discredit my attempt to help!
