Which Jet is bigger on a Nikki Carburetor? Briggs & Stratton engine. John Deere. 20hp, 22hp, 23hp

Here I explain why there are two different size Jets in the Nikki carburetor.

Thanks, I just got a used mower with that carb.

That is a confusing way to describe how to figure out which Jet goes where. The Carb will have an R and a L cast into it. The large opening jet goes on the R marked (right side) and the small hole jet goes on the L (left side).

Doing it opposite will make it impossible to tune the carb.
