Easy to remember, it's 50:1 ....incidentally I emailed Husqvarna one night with the same question, I was pleasantly surprised to have the answer in my inbox by morning. Good to see a big company with good customer service.
40:1
50"1 with the proper oil
Go 50:1.
50:1 with the appropriate two cycle oil.
50/1
50 to 1 is the best for all 2 cycles,
According to the manual, 50:1 (2%) for all engines.
The mix ratio is 50:1, but be sure to use a good 2 cycle oil such as Husqvarna's or Echo's. Do use a motor boat or motorcycle 2 cycle oil. Those are not rated for the small engines like used in the 141 chainsaw. Best bet is to buy the oil at a reliable mower shop.
The best mixture ratio for this model is 50:1. You can also get away with 40:1.
The fuel mixture is 50:1. If you are using a cheap oil, you should consider mixing it 40:1.
