Hi Guys. I have a 23mm bored GX390 carb fitted to my GX200, currently its around 18hp at 8500rpm on pump gas on my dyno on a 1.1mm main jet, or 0.043" to you guys, standard air jet.
What emulsion tubes are you guys running in 390 carbs?.....the one currently fitted to my bored carb looks very similar to a gx140 emulsion tube, but its a bit longer and the small upper side holes are slightly different position. What type is this???.....does anyone have a part number as I want to order some more.
