ok cool...never ran any saw with any mods so i will take baby steps lol...Both run strong the way they are tho..
Not like my 5100S...which is wicked fast....prolly about as fast as a stock 044 in wood under 18" or so....but then its had full woods mods.

When I had my 7900 I muffler moded it buy cutting the end off the internal baffle and ditching the spark screen. It picked up a small amount by doing this, but no where close to the effect a muffler mod had on my Husky 372's, 346, and Stihl 440.

Off topic: Sorry
Rydaddy,
Which would you rather have in decent size hardwood with a 20" or 24" bar, a stock 7900 or the DN 361?:help:
Please don't say both because I can resist anything..... but temptation.

20" bar = DN361
24" bar = 7900
Sorry, I realize that I kind of answered "both" but I consider it a (2) part question when you say 20" and 24" bar. If you have a saw larger then the 361 or the 7900 then you would probably prefer the DN361. But, if the 361 would be your largest saw... then you might like the 7900 better because it balances better with the 24" bar. 361 is a little nose heavy with a 24". Sorry if I just made things worse for you. You can't go wrong either way. If it helps, I may be selling my 361 because I don't think it will get used as much between my 5100 and 7900.
Edit... what did I just say? Basically if you are looking to add a "larger" saw to your line-up go with the 7900.

Well, even thought you said both, it's a help. I cut from a lot behind my house for firewood. I'm cutting more these days, and many of the trees are decent size. I've used an 029 w/ 20" for 12 years and it always seems a little short on power.
So, I don't really need, but I want a bigger saw. I really think I'd use a 20" bar about 80% of the time, and use a 24" the other 20%. I guess I'm doing it 100% with the 20" bar now, but sometimes want a longer bar and more guts.
The 7900 really seemed like a no brainer, but, then I'd want a 401 for small stuff. I thought the DN 361 might get it all done. Seems like a 7900 and DN 361 would be in a similar price range.
Oh, thanks for the quick reply.
Keep a sharp tool,
Jack
