I wouldn't worry about it. I use 32:1 mix in everything, including 50:1 units. It will smoke more and if you really overdid it, it might foul the plug.

As Bay has indicated if you notice a little more smoke than usual , don't fret it . If the saw begins to heat up or lose power ensure to add additional oil . 50:1 ratio with today's premium grade 2-stroke oil is more than adequate . Keep an eye on the spark plug colouration , it should be medium brown not black and oily excessive oil mix or light tan colour which much to lean for prolonged cutting use .

Thanks for the reassurances. As it happens, so far, the 6 to 9 inches. We were expecting turned out to be only about 3 which came in 1.5" batches that melted right away. I didn't even need to start the machine up. I am pretty confident that whatever the mix, it is reasonably close. +/-.

Wmas , well were getting the white stuff you missed lol . Actually I incorrectly stated saw , but blower or trimmer even just keep a good eye on plug colouration and you can't go wrong . 50:1 is pretty well the current safe mix ratio for all 2-stroke small engines . Have fun Bro !
