I have an 87 Straight six with a little issue. When I squeeze the fuel bulb to prime the fuel pump, fuel will leak out of one of the carbs....

I looked closely today, and found that Carb 3 (on the bottom) is leaking fuel out of the back drag air jet.

Other than their basic function, I'm clueless on carbs.....should the fuel be leaking here? I have a theory on why it may be doing this.....maybe the float is stuck down, or not sealing the needle/seat under pressure.

Is this something I need to worry about?

Thanks again!

Robbie, The carb float is likely bad or the inlet needle and seat are bad or both, causing that flooding. The new fuel also disolves the old floats. I recommend you pull the carb tops and inspect the floats, inlet needles and seats. Replace all bad floats and likely the inlet needles and seats.
