Front carb flooding after hard braking

I read in here somewhere, that after closing the throttle and hard braking - it causes unspent fuel to jump from the rear carb into the the front carb and flood it out....then a loss of power until the extra fuel gets used.

I can't find the post, but it sounded like..."yep, it's a design flaw..."

Recently, I've had a number of confidence inspired late-braking opportunities (after the long straight) on the track, only to be followed by a massive loss of power when rolling on the throttle at the next apex...probably ticking off anyone following me. This happened numerous times throughout the day.

Has anyone found a work-around or a solution to this??

One friend suggested putting something in between the stacks to prevent this, but where would that fuel go?
Another friend suggested 'Just don't brake so hard and carry more speed through the turn!'

Help.

RCVTR is an unknown quantity at this point
Like the thread that Wicky pointed to implies, the float vent tubes can be the cause. I routed my vent tubes together, pointing down between the carbs, instead of out the sides of the carb frames. The problem went away.

Same Here. I trimmed them shorter and routed them inside the carb assembly. Havent had any issues with it flooding since.
