Reply To: Champion 1j carb setting

[T.C.]

Low speed needle should be lightly closed and then turned 1/2 turn open… High speed should be closed and zero on the dial should be straight up and then turn it to 6… from what others have told me, and from starting my own, that’s normal start settings… but what most people don’t know or tell you is that you have to stay on the choke at about 1/4 to 1/3 until it gets a bit warm… if you just get it started and let go of the choke lever it “will die” almost immediately…

then you can fine tune the carburetor following the instructions in the file…
