[QUOTE="reelrazor, post: 823784, member: 54546"] Okay, on that link that Roost Rider gave ya? In purple it says 'air screw' and points to the air bleed passage. The little green bubbles flow into it at the right, past the air screw and the next stop is the needle jet(needle jet, emulsion tube, and nozzle are terms that get interchanged by different manufacturers/manual publishers). The main jet actually screws INTO it. It is what the slide needle lifts out of. If you take the throttle slide and main jet out, it [b]should[/b] FALL out of the carb body when you invert it. Most don't, especially if the carb has been 'cleaned' without removing or cleaning it. The needle jet/emulsion tube/nozzle has a hole all the way through it. The main jet controls flow of fuel into that hole. It also has a series of holes drilled sideways into it. These holes allowo air to be mixed with the fuel. These holes get plugged easily. The carb hasn't been cleaned until it, and its' bore have been cleaned. [/QUOTE]
