I will assume your carb clean was a complete operation. Let's examine how the choke works. The cable opens valves that will permit raw fuel to be sucked into the motor during cranking. Now, lets say that works fine.Your plugs should be wet after cranking for a short while. Y-N ? The most common cause of the plugs being dry after cranking is the throttle plates being open too far and causing insufficient vacuum. Same as opening the throttle while trying to start. When the intake air flow is too low, no fuel will be drawn in from the choke circuit. If the plugs are wet, you're flooding the motor. We start here. Additional checks of compression and a leak-down may be in order. This may take time to resolve. Get at it.

It ran before I got it but always took starter fluid in the air filter to get it going. I pulled the carbs and thoroughly cleaned them and used to compressed air in all the holes. However the bike still will not start without stater fluid and even then it takes along time with the fluid. I noticed that using the choke seemed to make no difference at all so, thinking that perhaps the choke isn't working at all I removed the carbs again (they are terrible to remove) and did what I could toi ensure the choke was working right. The mechanism moves as it should and I used compressed air in the holes to the where I presume the choke opens. Now, before I reinstall the carbs, any suggestions? Could the problem have been the choke or is there something else that would cause the same problem. By the way, once the bike was warmed up, it ran fine - just when it's cold I have to use starting fluid, Graham --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
