Predator 420 carburetor main jet.

[Studebaker]

I installed a high flow air filter and header on my Predator 420.
Now I need to rejet a Predator 420 carburetor, where do I start.
Any help would be greatly appreciated.

Thank You all for the help. I will get some jets and try to get it to run better.
I made the header.

Hello Studebaker,

I've got the same engine you do in a golf cart and am having the same issue you were with having to rejet. Can I ask which jet you ended up going with and where you found it? Thank you in advance for any help you might be able to give.

Eric.
