The float bowls are the thing's in the front and the back that the gas line runs into. Four 1/4 inch bolts hold them on, shown here, <img src="http://i41.photobucket.com/albums/e275/Jrgunn5150/Forums/F150/102_0409.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Now the float bowls don't just pop off, they probably need some persuasion, be careful though, it's just cast aluminum. When you get the front one off, you'll be looking at this probably, <img src="http://i41.photobucket.com/albums/e275/Jrgunn5150/Forums/F150/102_0415.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />This is the metering block, the thing in the middle is the much talked about powervalve, and the little brass screws with slots on them are my jet's. The jet's are numbered, mine are 66's, so I'll probably leave them as is for my 351w. This also needs to be persuaded off, once it is, it should look like this, <img src="http://i41.photobucket.com/albums/e275/Jrgunn5150/Forums/F150/102_0416.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Now you're looking at the main body of the carb, the part Franklin2 is talking about filing flat. The rear float bowl comes off the same way as the front, but with an exception if you are using a 4160 (vacuum secondary "single" pumper), this here, <img src="http://i41.photobucket.com/albums/e275/Jrgunn5150/Forums/F150/102_0419.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />This is a metering plate, and all 4160's have them. The rear (secondary, 4bbl, whatever you like to call it), is fixed from the factory with this plate, no jet's to change or adjust in the back. Doesn't bother me a bit, because I don't need to, and if I do later, Holley makes a conversion kit to bolt a "Double Pumper" metering block and float bowl back there anyway. It uses those funky "clutch screws" to hold it on, I just used a Phillips head and some care to remove them. The correct tool is sold in stores if you want it.Here it is removed, <img src="http://i41.photobucket.com/albums/e275/Jrgunn5150/Forums/F150/102_0420.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Up next you'll need to turn the carb over to remove the baseplate, take these six screws off<img src="http://i41.photobucket.com/albums/e275/Jrgunn5150/Forums/F150/015.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />You should now have this, Main body alone, <img src="http://i41.photobucket.com/albums/e275/Jrgunn5150/Forums/F150/102_0425.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Base plate alone, <img src="http://i41.photobucket.com/albums/e275/Jrgunn5150/Forums/F150/102_0426.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />My base plate is effed up, so I'm gonna have to disassemble it and clean it and the bores, I also need to replace my throttle shaft bushings. The throttle shafts come out by removing these two screws and the butterflies themselves, <img src="http://i41.photobucket.com/albums/e275/Jrgunn5150/Forums/F150/102_0430.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Then you can work the shafts out, I had to file thread turds off mine to get them through the bore. Now if you are just doing a simple re-gasket, you can pretty much reassemble, you don't need to mess with the shafts. I mean check them for smooth operation, and poop, and just clean and reuse if they are decent. Mine aren't unfortunately.One other thing to talk about is the accelerator pump, shown here, <img src="http://i41.photobucket.com/albums/e275/Jrgunn5150/Forums/F150/102_0438.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Four screws hold it in in the bottom, and there's a rubber nipple inside the float bowl. This get's replaced as part of a simple rebuild, so don't forget it. Here is everything in mine, newer ones have a weight and spring on them.<img src="http://i41.photobucket.com/albums/e275/Jrgunn5150/Forums/F150/102_0439.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />That's my progress thus far, I'll update as I move along and collect parts.</blockquote>
