Jetting Gx340

[Pacesetter]

Just picked up a used Honda Gx340 for $100. I am starting with the usual filter and header. My Predator 212 needed an upsized jet after these upgrade so I assume this one will need it as well. What size should I go with? Thanks.

It depends on the motor, you will have to do a plug test after the mods, then usually drill one size up at a time till the plug looks good. Others will chime in as to the correct way of the plug test and the color. About tan I think it was.

Yep, light brown is good. White or very light is too lean, and dark to black is too rich.

Came across this, and there were a few things in there I didn't know. Good read.

Thought it was bump worthy...
In depth plug reading. Enjoy.
