booster location inside venturi

[JOHNDOE333]

Hello all,

Any thoughts on the ideal booster location inside a venturi on a carburetor with regards to fuel exit hole, booster top or bottom. Basically, what I am trying to figure out is what are the pros and cons of straight leg booster versus a "down leg" where the booster sits lower inside the venturi or actually right at the tightest section.

-Good Day

You want the bottom of the booster at the or just below the tightest point so as to get the strongest signal for quickest fuel discharge response.
