Changed Main Jet
This is my first attempt, so it may be too basic for many of you. I have a Genuine Buddy 125, that is very similar to Chinese GY6 scooters.
Plug doesn’t look bad in stock tune, but still on the lean side. I opened the inspection lid under the seat but I’m going to need more space to remove the float bowl. Removed the storage box under the seat to get more hand room. Rotated the carb and removed the float bowl. *Use a new screw driver on carb repairs, rather than your fav old screw driver. Carb screws are small and easy to strip.* Main jet is right there in the center, on the bottom of the carb. My stock jet is a 92. (Chinese GY6 jets have a different jet numbering system than my Genuine/PGO. Pull out your stock jet and ID it before ordering new jets. You are going to spill a good amount of fuel out the vent when you rotate the carb, so roll it outside the garage and use a rag or something to catch it. Put it back together and took a short test ride. No leaks.
