Float Level setting and how it affects jetting

[QUOTE="canyncarvr, post: 636001, member: 16552"] Sorry guys. '..the float level CANNOT change your jetting [b]requirements[/b] in the carb.' All well and good. Wrong, but nice. It most certainly does change the [b]EFFECT[/b] of the air/fuel mixing process and resultantly, the air/fuel mixture. How does the fuel get from the bowl to the airstream in the first place? It is [b]pushed[/b] by atmospheric pressure into a space of [b]lesser pressure[/b] (caused by the venturi effect of the carb). The farther the fuel has to be pushed, the more pressure is required, or....with the same pressure being applied, the [b]less[/b] fuel will come out the other end. Put a 1 1/2HP well pump on a 2' long piece of 1 1/2" pipe. Turn it on. Get a LOT of water. Put that same pump 300' down, connect it with 1/2" pipe. Turn it on. You won't get squat. Well, comparatively. Point of fact: Lowering the float level (and thus the fuel level) will indeed have the effect of leaning the A/F mixture. Less fuel gets 'pushed' out cuz it has farther to [b]be[/b] pushed. In my case, a change from 16mm to 17mm float drop made the difference pee-wise. Two jet sizes? Nope. Not even close. [/QUOTE]
