I have an 85 cj7 with the inline six with the carter bbd carb. I am in need of a set of gently used metering rods for the carb. The number on the rods themself is 2376. If any one has a set let me know. <img src="/forums/images/graemlins/patriot.gif" alt="" /> <img src="/forums/images/graemlins/cheers.gif" alt="" />

Did you mangle yours?

I didnt mangle them. What happened is that when I did a carb rebuild on my carter one of the metering rods was stuck not working. It looked like carbon buildup. I was able to get it out and then I was able to clean it up with some fine steel wool and it seems to be working fine. My brother the mechanic tells me that I have now scored or scratched the metering rod and yes though it is workign it will not function correctly. Thats why I would like a gently used pair to replace them with as I am not able to find new ones. <img src="/forums/images/graemlins/lol.gif" alt="" /> <img src="/forums/images/graemlins/lol.gif" alt="" /> <img src="/forums/images/graemlins/lol.gif" alt="" /> <img src="/forums/images/graemlins/patriot.gif" alt="" /> <img src="/forums/images/graemlins/cheers.gif" alt="" /> <img src="/forums/images/graemlins/kewl.gif" alt="" />

Ok then there is a very FINE adjustment you can do at the top of the rod. As you know the rod is LIFTED in the jet as the throttle is opened. You can make a fine adjustment by LOWERING the rod. then as it is lifted the smaller part is a bit deeper and will come out later..
WARNING!! If you get it too lean the tops of your pistons and the valves will suffer!!
My opinion...If only steel wool was used I'd forget about it!

Thanks Jim, What is the best way to tell if I am running it to lean.

Your sparks get pure white with a glaze on them! By the time they glaze over you prolly already have burnt something in a daily driver.. Unless you have noticeably thinned the rods I would leave them alone!!
I have discarded a dozen of more carbs with rods in them... I wish I had saved one I would send the rods to you.. but sadly none left.

I checked my spark plugs saturday and noticed they were white. I will change them and adjust the carb to run richer and see what happens. otherwise the jeep is running like a champ. It even idles great.

Ok Big Jim in reference to this adjustment. What I have done is to loosen the screw that holds the metering rods in place. Thus letting the rods fall all the way in to there bores. Then I applied light pressure i.e. bring them up slightly then tighten the screw. Is this the proper way of adjusting this.

I'm not looking at a rod.. But as I remember they are the same dia till they start to taper. There is a fine line to where the taper should be at any given throttle opening. Is there a schematic in the KIT directions?
If you put them too low the richness will not reach the throttle opening at the correct time... The mixture may be too lean causing bad things to the pistons and the valves.
Remember a "too lean" mixture will run much better than a too rich one.. BUT at the danger of burning things up in there.
Modern computer engines run the engine TOO LEAN for a while and then bump some richness in it too cool off the combustion chamber and then back to too lean again.. All this for a bit of gas milage...but it works.
