I bought a small Honda dirt bike with this carburetor on it. Turns out it is missing the needle. The bike itself is made from various parts (mostly Honda). There is a "custom" adapter be twine this carburetor and the engine leading me to believe it is not original to this bike.
What did it come off of? When was it made? Added (1). The only markings i can find are "CA95D" and "H1" or "HI". Front opening is a bought 28mm.
