7310 Owners, still happy?

In fact they make 120cc saws but you can't buy them here thanks to the EPA.
Forum member "robinwood" will ship you one from Indonesia for a reasonable price.
Echo CS-1201

That's cool that the make a bigger saw but the specs kind of scare me, only 6.83hp? The stihl 660 is listed at more than that being a 92cc saw. I feel like it should be closer to 8HP for the displacement of the saw.

I’m pretty sure the 1201 takes the large mount 3002 Stihl bars

That would be cool. It definitely resembles an old Stihl.

They’ve traded a couple hp for torque. Kind of like a diesel truck motor. Might only be 350 hp, but 1500-2000 pounds of torque

Echo has a focus on reliability and durability along with evolution of design (rather than revolution), which is a common Japanese philosophy.

None of their saws off the showroom floor will wow experts in terms of speed and power, but that's OK, they have good torque and cut fast enough that most folks won't notice.

I tend to recommend their products to budget sensitive people who just need things to work reliably. They're kinda the Toyota of the chainsaw world to some extent (minus the big sales volume).

In my opinion, their entry level saws are superior to Stihl/Husky entry-level saws. The pro line saws (I think identified by the "X series" term) offer good value and torque, but some of them haven't been updated in a while and the usability features and tech haven't kept up with Stihl/Husky.

It seems they're very focused on electric saw development these days and are slowly backing away from gas in North America. They're also comfortable focusing more on arborists and homeowners than the big saw crowd. I sense the 7310 will be one of their last big pro saw releases and they probably won't pursue anything over the 70cc class for the US market moving forward.

That was kind of my first thought but I don't think the math works out for the saw.

Torque=5252 X HP
.................RPM

But real world results is all that really matter and the could be a monster.

All that ratio really means is that the torque and horsepower values are the same at 5252 RPM. If an engine has more ft lbs of torque than HP, it will make its maximum horsepower below 5252 RPM. If it makes more horsepower than ft lbs of torque, it will make it above 5252.

Larger saws typically turn fewer RPM and are geared/ported more towards torque. The horsepower gets held back a little bit, say 7HP, and their porting gets them around 5–6 foot pounds of torque rather than 3 or 4 foot pounds on faster 90 cc saws

Joe shows the 7310 stock and then ported in graph. @Red97

Here I would be checking with Joe or Kevin @huskihl

Local had one and hated it stock compared to his clone 372. Weight wise and in cut. 15lbs pho dry.

Now Mitch said he got his first 7310 he worked over to out cut his best OE 372 in the cuts. That tells me they take to porting good by right people.

I had a 7310 on the dyno that was up around 8HP at its peak, but it wasn’t cutting the same speed one of my ported 372s or 572s. But I do think the Echo is built better and will outlast other 70 cc saws
