Strange situation but here it goes. i always use seafoam in my gas but i still took carb apart and cleaned. i replaced the spark plug, fuel filter and air filter.

My blower will only start if i lock the trigger at full throttle. As soon as i release and idle it dies. i even got so frustrated i replaced the carb, still not a fix. Not sure what else to do.

anyone have thoughts on what might be causing this problem?
