The 150BT, 150BF, 350BT, 350BF, 2012-10 have a service bulletin, within a certain serial number range, for carburetor and ignition coil replacement for engine pinging.
Sorry - posted to wrong recipient. Redirected.
---------------------
Where does an owner of a 350BT find out more about the service bulletin? My 350BT, which is about 8 times used from new, won't rev up to full power and has a knocking sound that appears to be coming from the engine. Spark plug replaced, fuel filter very clean - neither fixed the issue. Help?
Thank you for contacting the Answer Army.
I'm glad that Husqvarna was able to take care of your issues.
Thank you for you business.
