Not sure if the husqvarna 345 Petrol saw is special but most 2-stroke engines use a ratio of 50:1 petrol:oil. However a little more oil doesnt make much difference to the running so your suggestion of 40:1 would also suffice.

A lot depends on which grade of oil that you use. If you use just cheap two stroke oil then 20:1 is better, but if you use a good quality two stroke motorcycle oil then 40:1 is better.
