    Hey All,
    I have A 84 Blazer with a Edelbrock Carb (600 cfm). I bought the Blazer in a lower elevation town, and brought
    it up where I live in the mountains. The prob is I need to re-jet it. I drove to Summit Racing today to get a new
    calibration kit. They said there would be instructions inside the box and when I got home, of course there was no instructions in the kit. To make thing short I need to know what jet to use in the carb. I have a choice of .095, .098,
    or .101 . Then there is the metering rods .070 x .037, .073 x .042 , or .073 x .047. Any help would be great!!
    Thanks All

    love my blazer, and 43 carryall

    look at the size of your jets and go 1 smaller until you get the right one...don't just put in the smallest one cause you'll be back at square one...

    I've got the Edelbrock book and it goes through all the diferent ways you can change your mixture. Judging by the jet sizes and the metering rod sizes, I'm guessing you have the #1406, 600 CFM with the electric choke. I don't know if you need to go richer or leaner though. I live at sea-level and have never needed to change the settings on mine before.
    1 stage leaner than 'stock' is as follows. .095 main jet and 073x047 metering rod. 1 stage richer is .098 jet and 073x042 metering rods. Let me know exactly which way you're supposed to go for power and cruise and I'll see if I can help more, the book is right in front of me.

    Hey Guys,
    Thanks for all the help. It's a little late to work on it right now, plus the X-file is on. As soon as I get it done I'll let you know!!

    Thanks again Todd
