Echo pb-251 won't run with out choke - Echo Gas Blower 135 MPH390 CFM Blower PB250

SOURCE: I have a Echo PB/251 Gas Blower which I recently

Check the muffler and/or spark arrestor screen in the muffler outlet pipe and also the engine's exhaust port behind the muffler. These are prone to carbon-clogging and the engine cannot "BREATHE" enough to reach full throttle. If all-clear in the muffler, go back in the carb and locate the inlet screen directly opposite of the inlet needle. Carefully pull it out with a pick and hold it up to a light source. If you cannot see thru it, replace it. This is another, (less) common area of obstruction.

Hope this helps,
