Echo Backpack Blower Engine Rebuild

This Echo PB-500H blower is locked up. It belonged to one of Ken's (@KensSmallEngineRepair) customers. The customer declined the repair and told Ken to to keep it. Ken sent it our way. I was told it was staight gassed and needs a rebuild. So lets rebuild it!

I no longer use Harbor Freight Super Heavy Duty Degreaser in my ultrasonic cleaner. Harbor Freight changed the recipe. The bottle previously stated "NON-CORROSIVE". Now it says "CORROSIVE", "do not user on Aluminum". It now damages most carburetors. Recently I have been using Simple Green PRO HD with good results.
