What are jets for?

[Hoze513]

I got a 2 stroke engine with a CNS V2 carburetor. I don't understand what the 2 jets on the crab do? And why is it important to change them. Can someone please explain this? Thank you

why do you think you need to change them?
they supply the engine with the proper fuel mixture...

So what Are the two screws on the side of the crab for? Are those the jets? I thought maybe different mm size jets do different things. Thanks

read a page or two from the link?, those are idle/ idle mixture screws. The actual jet is in the bottom of the float bowl. What's your plug saying?

Jets are designed to dictate the fuel flow through the carburetor. The larger the jets, the more fuel is able to flow from the carbs.
