Hello

So having issues with my weed wacker. . I left it outside and had over 2 days of rain . Barley got it to start and once I did it spit ton of rust out the muffler. Now it seems like it’s idling high(. String head moves by itself ).

Also when I throttle up , it’s boggles than shuts down

Gas is good . Spark plug is brand new

Thanks !

Gasoline engines don't like water very much. I figure you've got water in the gas and carburetor. If it was mine this is what I would try first. Drain all the existing gas out of tank and add new fresh fuel mixture. Get a small can of Chemtool from your local Wal Marts for about $4.00. Pour about a cap full in the gas. Fire it up and just let it run a while and give the Chemtool a chance to work. The engine must be running for it to work. A lot of times it can save you from have to pull a carburetor off and clean it. My 2 cents:>) Bob

BTW-Here is a link to introduce you to the Chemtool product. I have very good results with it.
