Gas spitting/leaking out of carburator air filter with high RPM vibration

[Street Ryderz]

Ok it honestly isnt much of a problem. It only spits gas into the air filter at full throttle. And even then it isn't much + I have a decent tight seal on my velocity stack and it doesnt spit it far enough to come out. Main problem is that the float bowl leaks at full throttle, I thought the two were related.

Then as Furry said retarding the timming will help reduce vibrations all around,Excessive vibes at the carb can cause bubbles in the float bowl those bubbles can create pressure in the bowl that pressure would cause an intermitant richer flow since the easiest way for the pressure to vent is out the jet that provides the least resistance.If the fuel is leaking out the seal between carb body and bowl and only at WOT then there is somthing else causing it,The float level while at WOT would be below the shut off point as it's constantly depleating the fuel in the bowl and being refilled.The seal it's self may be no good or not tight enough it's hard to say but worth looking at.
