Os 46 AX. will run when primed then die

by Travis Susee

Os 46 AX. I can cover the carb with my finger and it will prime and then start right up. But as soon as it runs through the prime it dies. I can see the fuel running through the fuel line but it wont fire. It's got a remote needle valve. I have a brand new spare one I'm thinking about replacing it with. Am I on the right track?

Before replacing the needle valve, crank it all the way down, then back it out about 2.5 turns (following the instructions for a break in). Also check if the glow plug is good or not.
