AKheathen Posted May 20, 2011 Report Posted May 20, 2011 nice for you to go through with making the vid..... i know i, and some others have planned on it, but never went through with it, lol........ anyways, i just have some things to point out, mainly terminology...... 1- the 2 tubes on the side are vent tubes. the overflow tube its the diagonal one inside the bowl that bypasses the drain screw. it is real common to see that people have over-tightened, and even stripped the drainscrew, not knowing this. 2- the airscrew is just an airscrew, and not called anything else, aside from "idle air mixture" 3- what you refer to as the needle jet, is just the needle. the tube it goes into is generealy the needle jet, which also holds the main jet. fun fact about banshee/blaster carbs- to the best of my knowledge, they are the only carbs that have replaced the needle jet with an emultion tube, which should also be cleaned. the tube is held in by the main jet washer, so it is real important to not loose that washer when you remove the main jet. 4 one reason to remove the main jet, is that it holds that plastic shield on, which is blocking access to remove the pilot jet, which should be removed, to make sure it is not blocked by debris/build-up, or even to change it out for tuning needs. 5- for purposes of ordering new, the float "plunger and jet" are actually called the float "needle and seat"... it is a good idea to make sure the shock spring moves ok inside tha back of the float needle, where it rides the float tang. also, very important to get that wire on there the way it came off, or could cause issues. also, point ut that you want to closely inspect the rubber (sometimes metal) tip for cracking, or hard glazing that is indented. you can blow through the fuel line, and actualte the needle to check for good seal 6- the range of the jets/needles. the main jet is in use from 1/4 to wot. it is 3/4 to wot that is all set by main jet size, and 3/4- under 1/4 throttle that the needle adjusts the main jet flow. idle to about 1/4 is pilot jet and airscrew. just under 1/4 throttle is the blending of the 2 circuits... imho, it's good to have most of the components removed to spray down the body/passages Quote
