No question, just a comment. I have a 21-year-old Ryobi gas powered grass trimmer. Have replaced so many parts to keep it running that I’ve lost count. It just won’t die. Tried starting this morning and it would run for a short time and then putter out. So I added some Sea Foam. After getting it running again things started clear, then the idle went back as smooth as new. Thanks for the great product!
