I got a kick out of this russhd1977. Be careful, or you'll give me a big head. Compared to some, if not most, of the guys in this forum, I'm a babe in the woods. I'm somewhat mechanically challenged, and can break stuff with the best of them. Maybe better. But I do think I'll try one of those yellow chains pretty quick.

Correct me if I'm wrong -- running 40:1 means there is less fuel in each gallon of mix than 50:1. So a carb tuned for 50:1 will run slightly *lean* on 40:1. Not a whole lot, but definitely leaner. Right? So if you do run more oil than the carb has been tuned at, you should richen up the carb.
Had to hop on board and add my years experience.I spent 12 years Air Force.Just thought this might be relevant, B52-G model! Ken
I should figure out how many actual cutting hours it takes to cut 10 cords.

You've got it backwards. There is more oil at 40/1 than 50/1. 128oz/40=3.2oz. of oil. 128oz./50=2.56oz. of oil. So with 3.2 oz of oil in every gal. of gas(128oz.) you have a richer mixture than at 50 /1.

It's funny you mention this Ken. I was a high school drop out at 17. Joined the Marines for 8 years. Viet Nam vet. Used the GI bill to get me some smarts. Was an accountant for 20 years. Never in a million years did I think I would ever be teaching at a technical college. But I absolutely luv it.
Happy Holidays back atcha.

Education & new saw rep sent, I should've included veteran :msp_thumbup: rep as well.
Ignore the 290 maligners, you bought a proven workhorse. Take good care of it (it sounds like you're a proper maintenance kind of guy) and it'll keep you in wood for many years.
Congrats. I'm sure someone will make the comment that you could have gotten a better saw for the same $ but you are the one who will use the saw. 290(029) is an excellent saw as evidenced by how long they've been in production.

I agree saw Doctor. I just didn't wanna get in over my head with this new saw until I get use to it. I could take the 3 extra chains back and exchange them for the yellow ones. Maybe I'll do that. Is there like a huge cutting difference when using the yellow chains as opposed to the green safety chains? Do the yellow chains get dull faster? Are they any harder to sharpen?

Congratulations! The MS290 is a great saw, I muffler modded mine before the first tank of fuel went through it,and removed the carb limiters.
I wasn't worried about the warranty.Don't be disappointed that it isn't a pro grade saw,It's well built and has proven to be reliable.
I know of some pro grade saws that are sitting around with blown pistons,and the 'ol 029's/290's are still running strong.

I'm the OP.
I made some assumptions and calculations, which could be way off, but here's what I got.
These are just rough calculations and "guesstimates".
Pieces needed for 1 face cord = 275
Pieces needed for 1 full cord = 825
Average diameter of trees I cut = 12 inches
Length of rounds I cut = 16 inches
Pieces per round (4 way split) = 4
Rounds needed for 1 face cord = 275/4=68.75
Rounds needed for 1 full cord = 825/4=206.25
8' logs need for 1 face cord = (68.75 X 16)/96 = 11.45
8' logs needed for 1 full cord = 11.45 X 3 = 34.35
I haven't actually timed this so I arbitrarily used 15 seconds as the trigger time on the saw to cut a 12 inch diameter round.
So using the above formula, it takes roughly 17.2 minutes to cut 1 face cord. (15 x 68.75)/60 = 17.1875 minutes
And 17.875 minutes x 30 face cords (= 10 full cords) = 8.59 hours.
This is just the actual trigger time on the saw to cut the rounds.
It doesn't include any time to cut the trees down, or limbing them out, or idle time on the saw.
