ok i'm having a problem with my windshield wipers i'm needing to figure out what wire provides the power so i can tap it from another wire. i also have another question i am running an carter afb carburetor on an 350 i just came from Washington to Texas (200ft to 3000ft) i dont know what size metering rod to order i'm running very rich the only numbers i can find on the metering rods are 7147 right now and i cant find any thing on carter carbs from any shops near me can any one help me?

thanks josh

Good question! Not many people are aware of just how much 2K of elevation can change some carburetors!
Since Carter sold out to Edelbrock you can download all the information you need off of Edelbrocks web site. You can also use a digital Micrometer to check your own rods by measuring the two different "steps" on the rod, this will give you a starting point to go richer or leaner on the rods, BUT I think you will get better results by simply changing the rod springs, these little springs are operated by atmopheric pressure and vacumn.
Just as a point of interest, every one thousand feet you go up means 1/2 lb less atmospheric pressure. Anominal sea lever pressure of 14.7 will be 1 lb less at 2,000 feet, by changing the springs you can compensate for this slightly different pressure. However if you up 5,000 ', you will have to either change the metering rod or the jet.
Hope this helps,

You should be able to buy a air-fuel meter off the "net" for less than $15.00 if you want. I am guessing you have tried to adjust the fuel mixture. It may help some till you get the parts... Too lean is not good. Too rich may stink, it won't damage your engine.
