Echo PB-413H blower dies when throttle applied
I have an Echo PB-413H blower and this blower was working great but all of a sudden I can't keep the engine running past a fast idle. When I try to accelerate the engine it makes a deep throaty sound, almost like the choke is on, and dies. I have changed the fuel filter, air filter, replace the spark plug, taken the carb apart and cleaned it, replaced the fuel line from the tank to the carb - everything I can think of but no luck. It starts and idles great, but when I go to give it throttle, it dies. This problem seemed to happen all of a sudden - one day it was working the next it had a problem. Any advice would be greatly appreciated!
