Should adjust my mixtures screws there at about 2 1/2 out. Or should I look at other things, like the float and pump travel, as I adjusted those for less fuel?

PS: what does OFS stand for?

Thanks LG

Was it fully warmed up and still needing choke?

You can set the lean best idle again. Make sure your rpms are low. Like 600 to 800. And if you have a automatic they say to do it while in drive. Which means chocked and locked or someone on the brake while you do the tweeking.

Does it only want to die at a stop??
What does your vac. gauge show at idle. If you don't have a vac. gauge, GET ONE! Set your idle mix to the highest vac reading at about 700rpm

If you turn one of the screws in 1/4 turn and it starts to run rough you are correct.

If you open one of the screws 1/4 turn and the rpms pick up you are too lean.

I would(and this is how I do my BBD),back both screws out 1/8 turn at a time till you get the highest vac. reading. You will notice a much smoother idle also.

Ok you guys are right, i had it so if you turn it 1/4 in it would sputter not 1/4 out. Ill go and mess with it.

Also should i reset the floats and pump travel, if there to low could they kill power? Or if its running fine just leave it?

Is the vac. gauge needle pretty steady at +/- 1 Hg or so?
If your see'n 18 Hg at idle, your idle mix is pretty good then.
What is your altitude(ASL)?

Thank you all so so much! You guys have all helped very much!

Soon im going to start a bild/restoration thread for my Jeep where ill be asking questions about paint, dash board guages (John Strenk ), etc. Ill also be posting pictures of my progress.


Quick question, iv noticed that the only way i can keep the engine from flooding is to have the choke pulled out a little bit. Is it normal for the carb to like the choke closed off a bit? or do i need to re tune it again, if so what do i need to adjust?
Congratulations! Feels good, don't it? Now write down all of the Idle screw adjustments, timing, whatever you did to get to this place. That way next year, flip open the notebook to your emissions page and get it through. Good deal passing! God bless.

I'm 2734'(ASL)in my d'way.
With your vac. reading, and alt. I would say your idle mix is good.
If you speed the rpms up kinda slow. Does it stumble?
What about when you 'stomp-it'?

im assuming your talking about when its under load, and with the choke wide open. slow = no not really unless im at a steep hill or something, fast = yes
When I have the choke closed off a bit I don't have any problems.
