I heard there was no standard 046 and really there is no difference between the 044 and 044 Magnum. Not sure why some have the sticker and others don't. Is it really the wrist pin size or are there Magnums with 10mm wrist pins?
For the cutting I do, I don't think it would make a difference with 044 or 044 Magnum but I would still like to know what the reason is for putting a Magnum sticker on some saws and not on others.
EDIT: I found this thread:

Saw this posting in there:
There are some real differences between the 044 and the 044 Magnum. Carburetor, base gasket, port timing and finish, decompression valve, self-advancing ignition- these are all things that were upgrades on the 044 Magnum.
I was sold by our regional sales rep that all 046s sold in North America were the "Magnum" designation. He said there were de-tuned 046s models intended for the European and Asian markets and those would have similar differences as to the 044 and 044 Magnum.
I think the majority of the 044s that are out there are really standard ones with the $5 sticker on there. I did see one video of an 044 Magnum with a decompression button on it so I think the post does hold merit.
