    Tore apart my Rochester Quadrajet today (1986 K5 w/305). The easy part is done. I think putting it back together should be easy too, but I'm concerned about making the proper adjustmens once it's back together. I have the Haynes Rochester Carb book and it's helped a lot so far, but it looks pretty detailed when it discusses the adjustments. Any ideas or tips and tricks to make this go easy. It's my first time....

    I think the most important one is to set the float level properly. Also make sure it's spotless clean in the bowl. When assemblying, be careful not to put the top gasket upside down (happens easily).

    The only other adjustments you may wanna check while disassembled are rejetting or rerodding, but that's only if the carb is too rich or lean for your application or altitude.

    Good luck. If you have more questions, just post them up here.

    IN 86, you should have an Elctronic QJet. QME...It controls mixture automatically. If the electronics are working properly, you should now have to make any adjustments to it at al besides the float levels...
