I have a thumpstar 120 and I am not sure what carb it has on it. What is the best way to identify it? I see it has a 30 inside of a hexagon stamped on the one side of the carb. Do they make 30mm carbs or is it a 28mm and that 30 means nothing? I havnt really found much online about 30mm carbs so I am questioning this. I need a throttle needle for the carb since it is bent and need to know what to order and from where. The bike is running terrible right now!!

also what would be the stock settings out of the box for this carb? Thanks need help!!

Some clear pictures of the carb from various angles would be a lot better to help identify what type it is.

Figured it out. Took it to wholesale cycle and they said its a 28mm which I kind of figured it was. Way to much for 120cc stock thumpstar motor. Bought a 22mm carb today, put it on, started it, made a few adjustments and it runs perfectly now.
