Question:
Scott,
Thank you for responding to my knocking sound described in my last post on my 350bt blower. You advised low smoke oil and high octane fuel. As mentioned, my local Husky dealer mixed my oil and fuel. They used low smoke Husky two stroke oil, and I filled the fuel at the prescribed amount with no ethenol and i used 92 octane fuel from a local distrubutor who ensures me that it was fresh fuel. The station is in a moderatly poplulated area, so I know it is not old. So, is some spark knock normal for this blower? If so, why does my Husky trimmer and my Husky hedge trimmer not make any spark knock using the same oil fuel mix? Thanks for your help in this matter.
David
