Pin_Head said:There is a glass window on the front of the fuel bowl and you should see fuel half way up the window. If there is no fuel, this would explain why you need to crank it several seconds before it starts. Chances are that gas is evaporating. It is bad for fuel to repeatedly evaporate until the bowl is dry. This causes tar and gum to plug some of the critical passages. Fuel could also be siphoning out if the air vents in the fuel circuit are plugged. If it is siphoning out, you will see raw fuel in the bottom of the intake manifold when the bowl is empty. Does your carb cooling fan work?
Where are the vents? Mine will drain empty if it sits for 4 or 5 days.
I rebuilt the carb and it still does it. It runs fine, fires up and runs for 2 seconds and then stalls. Restart 2nd time and it runs fine then. Takes the first start to refill the bowl.
