How can I use Sea Foam in a Stihl chainsaw? [SOLVED]

Thanks for the question!

There are two ways that Sea Foam can be used to help your chainsaw: preventative maintenance, and restoring performance.

You can use Sea Foam in every tank of fuel to stabilize the fuel as it sits and prevent the formation of harmful gum and varnish in the fuel system. Add 1 oz per gallon to every tank.

To overcome a problem (like surging, or hard/no starting), here’s the best way to use a cleaning dose of Sea Foam to clear up any gum or varnish that’s causing problems: First, if the fuel is old, go ahead and drain it. Then, add 8 oz of fresh fuel and 4 oz of Sea Foam to the tank. Crank/rope pull/prime the engine to draw the mixture into the tank, and let it sit overnight before starting. Run it until empty before filling up with fresh fuel. That will do a great job cleaning up the carb.
