DMV was packed, drove around for a while, experienced a loss of power, hesitation maybe, happens I start to accelerate from a stop. Engine flutters than almost dies then picks up again jerking me forward then back. Happens a little if i shift too soon. Any ideas?

Go back to the last thing you adjusted(messed with). Make sure you have no loose wires, bolts, hoses, distributor hold down bolt. More often than not, tightening down a bolt, loose hose, or electrical connection is the culprit. God bless.

Yup, a maladjusted float could make problems, as well as a vacuum leak, or even timing. Just be methodical, and retrace your steps, You'll find it. God bless.

Ok so here is what I think happened, I went in this morning and fiddled with the floats, took it for a test drive and noticed the symptoms and mistook them for timing issues. At that point I had both a float and timing problem. Retraced my steps as you suggested, took the carb off the Jeep reset all the setting (for good measure, they turned out to be a little off anyway) and reset the timing. Haven't taken it for a test run but it idles smoother so that's a good sign.

You can leave the carb on the eng to do this step.
Remove the top section of the carb. that is held on buy the 6 screws.
BE CAREFUL! Don't lose the acc. pump spring, or the 2 'e' clips.
Now you can start the engine and see where the float level is.
See the two cut-outs at the top of the acc. pump shaft? You want the fuel level to the middle or just a bit more on those cut-outs.
You will need to plug the vac. line to have your eng run 'rite'.
Did you ever order the FSM that you REALLY need to have?

When you thread the fuel fitting into the carb and then you bend the tab to set float height......do not let the fuel fitting turn when your tightening the fuel line to it. That will drive the fitting deeper into the fuel bowl and lower your float height more than you think.

Also is it possible that a mixture that is to lean could cause this?

1/8 from the top is flood'n the engine.
Does the Haynes have a how to section for the carb?
Get a copy of the real FSM from AMC, MR-252 !!!!!!!!!!!!!!!!!!!!!
Go to NAPA, and buy a rebuild kit. It will have ALL the specs you need.
YES, you'll need to plug the bottom because it will be a vac. leak.

If it's a NAPA kit. It will have very good 'how-to's' with the rebuild instructions.
Do you still have those instructions?
1/4" will still flood the engine....Set the float as the instruction's say....
