Was the Echo CS-7310P a fad or is anyone running them?

[lehman live edge slab]

Sure, no prob babycakes!:

OG:

Large difference is inboard and outboard clutch for needing the extra clearance and for anything but noodling it’s not a big problem but yes when you have to noodle one it sucks when they plug. My old 045 is far better at not plugging than my newer ones.

Todays cutting, -2F outside. Was too lean on the low jet on both the 590 and the 7310p. Both saws acted completely different:

The 590, with the ignition advanced wouldn't settle into proper idle rpm. In the cut or left to idle It would cackle down low in the rpms. 1/4 turn was the difference.

Wheras the 7310p would lug low in the rpms at idle. Had to richen the low jet and raise up the idle speed. Had no power off idle.

I don't miss having to mess with carb tuning.
You must be having a heat wave in AK. It's colder down here.

Sometimes I forget a little carb screwdriver. I've actually bought 2 dozen of those dmn things and have spread them all over:
Truck, every tool box etc.

I got a half dozen floating around my tool box.
Both of the chainsaws I have are Autotune, but the OPE my son uses to do lawncare work are all Redmax and have adjustable carbs. Although the blower will be replaced this season with the new Redmax 9000 which has Autotune.
BTW you have mentioned elsewhere that you have found Autotune to run very lean. This hasn't been my expiereance at all with a 550xp mk2 and a 562xp V1. Both run slightly to the rich side. Same story with my Stihl MS400C.
I have ran these saws in all manner of weather and in elevations from 1500' to 8000'+. A few years ago I ran 4 tanks through the 400c at 8500' and 45 degrees and the next time I ran it two weeks latter it was at 2000' and 20 below zero. Never missed a beat. The 550xp hasn't been ran in extreme cold but has been ran in the same elevations. Initially it didn't run that well at high elevation. I think part of that was my fault and caused by the way I warmed the saw up. Changed my procedure a bit and haven't had an issues since.

Woah! 42" bar, nose burried, exj skip tooth chain and this 7310 didn't miss ah beat:

That's half rotted cottonwood. Very soft.

 

[mainer_in_ak]

Looks purdy solid, good chips. A big knotted section. If they rot badly, they're usually hollow. Jim ran a 395 same bar n chain for reference:

I wouldve milled it! Lotta colors in the big ones. In the heartwood: rust, chestnut, grey. Sap wood is bright.

Yep, purdy soft, they mill up easy. Really colorful one from coupla years back:

Looking at the end you can see it's spalted. This happens to cottonwood very fast.

Was a solid piece. I thought the saw did purdy good. Didnt bog, kept it's rpms, chain was still tight, oiled well, couldnt hear any clutch issues.

So with all your re-occurring tangents about wood density aside, did you think the 7310 did well in soft cottonwood with the 42" bar?

I'm a little confused Ben, you rarely if ever contribute any evidence, videos, photos or really anything about running saws. Same with the hunting forum as well. Or even greater knowledge or development of an idea or product.

BUT, you sure do contribute alot of criticism and doubt?

You're a smart guy who's had alot of unique life experience. I hope you contribute some positive things or at least share some of your progress, accomplishing something with chainsaws, hunting, etc.

I have been more or less passive on the hunting forum in question for 10 years. To many idiots. I do still use the classifieds as it's a a great source for hard to find items.
Why would I post videos here? No interest and I have no desire to re invent the wheel. At one point years ago I did have a you tube channel where I posted some videos. I got sick/bored with it.
I would also say I wasn't being critical. I was just pointing out that the wood was partially rotten cottonwood, which it clearly is. No 70cc saw is going to run a 42" bar well in substantial wood and certainly not the 7310, which is the weakest saw in its class.

Had another great day running the 7310. Limbed/bucked up a big spruce. Weather is too warm to move wood, snow is too soft. Hopefully some below zero temps return and my packed trail will set up like concrete.

Had to turn down the oiler. Saw runs 12,000 rpms in the soft white spruce, so ran out of oil while there was still a few ounces of gas left. I had the oiler set at max.

 

[mainer_in_ak]

Started moving all these big rounds of spruce and splitting them. Still can't put down this 7310p. So dmn smooth-cutting!

The recent ice storm we had really destroyed the woodland on our place and on my parent's farm. A large hickory tree at the edge of their back yard fell across the yard, barely missing the house. I salvaged what logs I could, and hauled the rest home for firewood. I used my relatively new Echo 7310 to section up the big stuff. I really like this saw, at least for the job it's intended for. It pulled a newly sharpened standard (non-skip) chain on a 28" bar through that tough stuff with no problem, even though at times the bar didn't reach the other side.

If any of you 7310 folks ever get a trashed/ scored piston, let me know. I need one as a test fit on a Shindaiwa Frankinsaw project…same 51mm size.

Thanks
