I'm hoping somebody out there can help me. I just installed a UniFilter on a Roketa GK-06 and when I went to install a larger diameter carburetor jet I found that the jets in my carburetor were very different from the one I wanted install. I think the carburetor is a Kazuma. Here's a picture of the float and jets and another of the carburetor. Can I replace the long main jet with a standard shorter jet? Any help would be much appreciated.

the main jet unscrews form the lomg part. sometimes when you unscrew the main it will unscrew the longer part of it.

hold the long part and the jet should just unscrew.

Thanks, Bige. Much appreciated.
