Carter BBD

I just put in an 83 258 in my Jeep, and have had no dealings with the infamous BBD till now.
It won't idle, unless I choke it almost closed, then it purrs like a kitten.
Engine was at normal operating temp, I byapassed the stepper motor (cut off the needles where they taper down), as I have no 'puter in my 1974, and there appears to be no vacuum leaks.
Any ideas?

Jeff

You may have seen this before, and since it runs with the choke closed, I don't know if it will help, but check this out:

Having to run with the choke nearly closed is a sign of fuel starvation. This typically happens because of a couple of factors. First, your idle mixture is either too rich or too lean. Secondly, your idle circuit of the carb is varnished causing a restriction in fuel flow thru the idle circuit. The idle circuit is basically the only part of the carb that continues to flow fuel no matter what the rpm range is. In other words, the idle circuit operates any time the engine is running. Because of this, it will affect the engine no matter what rpm you are running. You have to get the idle straightened out on a carb before you can even start tuning anything else.

"jeepsarecool" you hit it on the head, I pulled the carb apart, pulled out the venturi section, one of the tubes going down into the bottom of the carb was plugged up solid, cleaned it out and presto, smooth idle!

Thanks again
Jeff
