Metering rod adjustment??
Evening All,
I'm doing a rebuild on my Carter 1 bbl carb. I got the kit from NAPA. Jeep is a '75 CJ5 258. I am getting conflicting adjustments for the metering rod. The NAPA kit instructions say to bottom out the diaphram plunger then to turn the adjusting screw until it comes in contact with the linkage. Then turn in a 1 full turn. The conflict is with my Chiltons book. The Chiltons says to push the diaphram down until the Metering rod comes in contact) with the jet orifice. Then to turn in 1 turn. The chiltons instructions seem to make better sence due to the fact that if it was the other way my adjusting screw would be completely turned in with no adjustment left. Please send your views. -- Thanks Always !!! Paul '75 CJ5 258 Vail, CO. |

Hi Paul,
The metering rod is like a power jet of a normal carburetor. So, cruising, under full vacuum, the rod would pulled as far down in the jet as possible, so you would want it be not totally bottomed out, so screw the adjustment so it will back it off. Push the diaphragm shaft down, nothing else. The metering rod is number fifty for others interested: http://www.carburetorfactory.com/expvw01.html God Bless America, ßill O|||||||O mailto:-------------------- http://www.----------.com/ Paul Brogren wrote: > > Evening All, > I'm doing a rebuild on my Carter 1 bbl carb.

Re: Metering rod adjustment??
Thanks Bill,
I did push that diaphram (only) to bottomed out position, but when I adjust the screw to accomodate this position against the linkage, the set screw is threaded all the way. No adjustment left. I find that odd. I tried shimming with washer, but It doesn't seem to help. I'm obviously overlooking something. -- Thanks Always !!! Paul '75 CJ5 258 Vail, CO. "L.W.

Re: Metering rod adjustment??
Thanks Bill,
I did push that diaphram (only) to bottomed out position, but when I adjust the screw to accomodate this position against the linkage, the set screw is threaded all the way. No adjustment left. I find that odd. I tried shimming with washer, but It doesn't seem to help. I'm obviously overlooking something. -- Thanks Always !!! Paul '75 CJ5 258 Vail, CO. "L.W.

Re: Metering rod adjustment??
It may be the wrong kit, I can't imagine a need for an adjustment
unless every kit manufacturer has a different idea of what the diaphragm rod length should be. God how I hate Carters, even their AFB!
