• The hose in the tank with the filter on the free end connects directly to the carburetor input connection.
• If the saw is equipped with a primer bulb, an output line from the carburetor connects to the suction side of the primer (once the bulb is collapsed it draws fuel from the tank through the carburetor to refill as it inflates).
• The pressure side of the primer returns displaced fuel to the tank as it is depressed.

Afternoon Mac;
I am going to give you a qualified YES.
It is possible with Husqvarna and Echo.
All Stihl parts are proprietary and new OEM parts must be purchased through a local Stihl dealer. A phone call to your local store will answer your question and whether they have one in stock. If you do not want to utilize your local dealer eBay for a used part is your best option.

Just remove the spark plug, connect the wire, and lay the plug base on engine metal. Turn on the ignition and pull the starter. If nothing, first try a fresh plug gapped at 0.020". If still nothing, service on the ignition system is required. Suggest finding a Stihl service dealer if you don't have mechanical service skills. Hope this helps!
