ECHO CS-7310

Maybe credits from the bazillion blowers and weedwackers they sell.

Also it us easier to pass emissions when you are not trying to get every bit of power.

So does that mean the echo ports well?

Most of the echo saws gain well.

Then I guess there's no more power left in a ms170/180 considering how they are the worst on emissions.

I didn't realize they had power......

No, it is fully emission compliant (there are no credits in Europe, hence no 620 anymore and it is replaced with non-strato 621)

Don’t forget the engines are designed and built by biggest and best Japanese OPE manufacturer, in-house. They knew how to do it when Husqvarna bought Zenoah for strato patents and claimed it is impossible. It was possible then, it is also now (until 2025).
Sure, it takes a lot of voodoo with swirl control in the cylinder to burn everything and keep unburnt remains inside.
Just look at Yamabiko patents for port shapes and even left/right dimension differences for temperature difference compensation...

Of course, most Americans may perceive them as a “B brand” but it is just consumer brand perception which has nothing to do with engine build quality and engineering skills.

Not that simple. 50.1cc and 90cc engines have the same absolute THC (total hydrocarbon) limit which is not scaleable

Them darn hydrocarbons....

I assumed the bigger ones would be allowed more emissions.

The split is at 50cc almost everywhere - CARB, EPA and EU. So partly you’re correct - smallest engines (<50cc) are pushed harder than the bigger ones.

I wasn't belittling Echo or saying they're a B brand.

I just gave more general opinion seen from some forum people.
Definitely not aimed at you personally or in any offensive way.

I can appreciate made in Japan,especially from a society with a base for perfection.

Do the chains feel heavy on this saw...

Maybe the Echo 7310P is the real most overrated saw?

Nope, I saw one turned into a race saw in person, the guy who had it had many very modified/cool toys (Including a West Bend kart engine saw) and he said it was the best stock saw he ran and it only took a little bit of work to make it much, much better.

What's so funny?

Since it was called a killed thread i decided to be an arse.
I've heard plenty good about this saw.
