New airhead carb floast, are they pre-set?

Rapid Dog · 03-17-2011, 09:13 AM

Got mine in the box. Are they preset or should I have to fiddle about with the tangs?

Dont think they are pre-set, but they are always in the neighborhood. Its actually easy to check on these- just make sure that seam in the float is level with the carb body just as the the tang begins to engage the needle valve.

Cripes on the Yam XT you ned to make a separate clear tube and make sure the bike is level and then figure out 6mm below the carb seam... Makes the BMW seem no-nonsense.

They are not preset.

They should turn the gas on and off just as the tang is level with the carb body.

...so I've heard, so I'll ask...do bothe sides need to be the same for some technical reason.
Right now my right side needed to be lower than the left for the carb to not over flow. In otherwais e I had to bend the tang open farther.

That might be a float needle or needle seat issue. Both floats should be providing the same amount of gas in the bowl is whats ultimately important, and usually that means both are the same same. If one side is weird, then the floats are inconsistent, or the float valves are.

Or the overflow pipe is.

...hmmm...you mean I could have a mis-matched pair of float bowls?
I've replace nearly everything in these Bings, float needles and float hinge pins as well.
