if it burbles and won't get on the pipe, it's probably still too rich on the main... or your needle jet is all messed up or your needle setting is way off - is the needle jet seated all the way in the carb body, and is it clean and undamaged? i have seen the pin come out of the carb body that holds the needle jet... causes all kindsa wonky problems... i've also seen the split float style carbs loose their pins that hit the float arm and the float flops around on one side and lets all kinds of fuel in... your needle jet could also be all wallowed out ...

so with the correct needle does jetting now have an effect on how it runs? if the pilot circuit is good, have you moved the needle around yet to see if there's a change?

only way for it to use a bunch of gas is (afaik): too high float level, way big main, wrong needle jet/jet needle, cracked overflow tube, blown reeds..

i drop a size every 1000-1500 feet increase in elevation... i'm at 2500 feet to begin with, so i generally gotta go up a size everywhere i go around here..
