Question about Echo Gas Blower 135 MPH390 CFM Blower PB250
Posted by Anonymous on
You probably have the needle in the carb not shutting off or going back to shut off the fuel. What you need to do is rebuild the carb and most lawn shops can sell you a kit to do that. You can see videos on youtube.com as to how to do it if you are not familiar with the rebuild process it is not hard to accomplish. The kits are around $8.00. Hope this helps.

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,
