Air fuel mixture screw helps you dial in the perfect "purr" for your idling beast. When tuned right the Tao Tao TBR7 Purrs like a bobcat.
This is where the adventure begins. You found the right pilot jet (your idle) but she sounds a bit tight or lulls. So you want to adjust the air fuel mixture?. You realize on the Chinese bikes and Chinese clone carburetors you can not access the dang air fuel mixture screw without removing the carb... Ahhhhhhhhhhhhh
Of course I consult the all knowing oracle known as Google and come up with an extended air fuel mixture screw. Yep it does work! Because it is plastic I am a bit nervous with it. But it has been 1 month and serves me well. I live at sea level and travel up and down a few mountains. The air fuel mixture screw gets used at about 800 feet up. There are observation posts on many of our NY mountains, so I do climb a bit of altitude.
I did not use the above new spring as it was too long. I used the original spring that came with my new
Chinese Mikuni Clone carburetor. The original carburetor was sealed. The new carburetor I fitted with a 22.5 mm pilot jet and a 105 mm main jet.
You only have to take off the carburetor once for the air fuel mixture. Once installed you can reach the and turn the dial without carburetor removal. The numbers are nice to know how far you turned the knob.
I put the washer on top of the spring and then the seal on top of the washer. Insert and screw all the way in, GENTLY! Then bring out a turn and a half. From there adjust accordingly. Clockwise is less fuel and counter clockwise is more fuel added to the air fuel mixture. Really effects your idling range and throttle closed circumstances.
