how to adjust float???

My brother has a 84 short box chevy we just picked up. (see other thread titled "smoking and strong exhaust smell" for more info.

My question is this, how do I lower the float level, step by step, I have never been in a carb before? It is a stock quadrajet. Thanks a lot!!!!

ok first disconnect the fuel lines and unbolt the carb from the motor and put it on a flat surface u can work on. Ok now the top plate is held on by 4 or 6 screws i believe.. 4 or obvious and on the top and probably torex and black.. there are 2 more little flathead screws down between the primary butterfly's.. take them all off. Now carefully pull off the top plate with out ruining the gasket or your going to need a rebuild kit. Then you need to get a little ruler, comes in most rebuild kits.. that measures in 32nd's i believe and i would set it at 13/32. you measure this while pushing down on the hinged end of the float and and measuring from the top of the actually floaty part to the top of the carb body, there will be a lil notch to bend the float as needed.. hope that helps.

Use a small pin punch to tap the accelerator pump arm pivot pin inwards, but don't push it all the way until it stops. Leave a little space where you can put a small screwdriver blade behind it to pry it back in place later. Might try checking the float weight to see if it is gas-logged.
