Well I did mess with the idle screw a bit just to see what it did, I'll have to adjust it. You say they need to be closed? Also would a slightly off air/fuel mix be an additional problem to why it wont start?

The fuel tank is above the carbs, no incline can stop flow. Remove the fuel hose AND the vacuum hose. Apply the syringe vacuum and see if fuel flows properly. OK ? NOW, when you re-installed the carb pack, any chance you have the throttle cable adjusted wrong and the throttle plates are open somewhat ? That will make a bike very hard to start. Did you remove them from the runner when you cleaned them ? Just hunting around in the dark for any possibility. I'm not there, you are. If this bike ran even so-so before, then it's something you did. Question is what ? I suspect at this point, that the throttle plates are not closing. But then, I'm not there. I don't want you to have to start all over but it might come to that. Let's not beat up the starter motor and battery too much or you'll have even more problems. --- On Sat, 7/25/09, Torry Barker <[email protected]> wrote: >From: Torry Barker <[email protected]> >Subject: [Nighthawk Lovers] Re: Got tips? >To: [email protected] >Date: Saturday, July 25, 2009, 1:05 PM > > >I've already checked the float bowls and yes they have gas in them, the thing >is it took quite a long time to even get the bike to fire, as in 15-20 min. >And even then I had to have the "choke" open so it would let more fuel in, >come to think of it the hose that goes from the petcock to the carbs has a >slight incline before it drops to go to the carbs.
