I bought a non running blaster. Gas sat in it from last year so I took the carb apart and cleaned it. I saw the needle jet was slightly bent. I bent it back a little and put it back. It wasn't kicking over so I tried to pop start it. It runs when you pop start it but only really runs at full throttle. It dies at idle. If you go to kick it over after it was running it runs for about 5 seconds and dies. What should I do next? Does the needle jet need to be replaced?
