World Formula Carb Overflow

Anyone ever had issue with a WF and constant filling of catch can?

Picked up a WF for my Son to race and for the life of us we can not figure this out. Float height is good, replaced needle thinking it was possibly that. Even put a restrictor in the gas line to see if we could limit gas into bowl. Haven’t tried putting it in the pulse line. That’s a thought…

If we had this issue with 206, it always came back to float level.

Was told that WF carbs are hit or miss with problems.

As long as laps stay below 10, not a big deal. Anything more and can gets full enough to start sputtering.

Thoughts?
