Assuming you mean the float needles. Take a piece of clear fuel line and attach it to the carb drain, hold the tube upright against the carb body. When you open the carb drain screw it will fill the tube to the level of fuel in the carb. If it is either higher than the fuel bowl gasket, or significantly below it, or if one carb is different from the rest then you have a float needle in need of replacement. Sent via BlackBerry by AT&T

How can I tell if it's a needle seat Stanley? I'll see what I can find with the fuel shut off valve. --- On Sun, 7/10/11, stanley/ Randolph <[email protected]> wrote: From: stanley/ Randolph <[email protected]> Subject: Re: [Nighthawk Lovers] Engine surge To: [email protected] Date: Sunday, July 10, 2011, 5:31 AM Likely it is the carbs, loading up. Like, a needle seat maybe? If not, a vacuum leak of some sort. The fuel shutoff valve?

I know these bikes are unmanaged but it may be something similar. -Kyle On Jul 5, 2011 12:58 PM, "Kim Paddock" <[email protected]> wrote: > Hi all!
