Echo 590 vs 620P

[Cut4fun]

@Nutball the one I stated was with 24" on 620. Not all of the ones listed left.

Here is his prices. But it might be ending this weekend.

Nice. Why is 2511T more than 355T?

Because they are special. So small even to the little bigger 271, let alone the 355. Smaller then 150 too.

Someone sent me this pic to show when first came out.

Are they both magnesium cased?
I am ECHO illiterate on their numbering. 2511, 355...
What's the difference?

 

[Nutball]

25cc vs 35cc, plastic with aluminum blocks. The power of the 2511t is rated roughly the same as many other echo models smaller than 35cc.

Are they both clamshells?

 

[Nutball]

2511t is the only non clamshell under 50cc.

I cut the oil lines shorter, and have been tinkering with that aspect. I think if they made the oil filter all smooth (without the plastic cage) and made it slightly heavier, and found some way to not have a case gasket sticking out in the tank, the filter would easily be able to fall to either side of the tank. It takes a little knocking around, but I've got it to where it can find both sides of the tank.

As Nutball said, the 2511T is not a clamshell, but it's not a full traditional mag case either. Same setup as a MS150/MS151 with a metal crankcase but the oil tank is plastic.

Don't want to derail further off the 590/620, but boy the 2511 is a nice saw. $330 out the door on the dealer day, even if the MS151 improves performance as much as Stihl's claiming, the Echo will remain a great value. Hit a bolt from a rope swing halfway through this big pine pruning and had to send down for the 200T...huge difference in size and weight if you're doing pruning or other smaller work...love it with .043 3/8 stihl bar/chain.

Easy 160psi hot on the 620, slowly worked up to 165psi before I got tired. Looks like it matched the 372 with 3 not quite perfect test cuts on the same log, still heading toward the bigger end. I'm not at a computer right now for a precise look, but on the camera it looks like 13s, 14.5s, 15s for times, with the first cut being near perfect, the second I tried to let it rev a little faster, and the third had some minor clutch slippage.

It's mild mannered, handling similar to the 372: high max revs, likes high revs in the cut, but still capable of good low end torque.

And I pulled the oil cap tether ring off, it was preventing the filter from falling back to the clutch side.

I have an idea for making it extra loud and extra high flow, but this was loud enough. I removed the inner deflector, opened the screw tubes, and added the side slit. The 590 muffler was done the same, but with 2 extra holes added to the baffle, since it has smaller holes anyway.

I just finished a 620.......

Fantastic saws for the money.

That seems to be the general consensus! I've been stashing some cash to purchase either a used 50cc saw or new, and I've been eyeing the 501p...

Good solid saws.

So you left tube in? So nothing done behind tube area?

I saw where Andre @andyshine77 removed the one he did.

I left it in the one I did. But opened back behind it.

I like your outer half slit too. I do that on 60cc 54cc poulans etc.

 

[Nutball]

I would drill out behind the tube as part of really maximizing flow, but I wasn't aiming for making it as loud as possible. These saws already have a poppy tone. Something else I'd try if sound isn't an issue is, drilling 2 big, maybe 3/4", holes on each side of the inner tube through the front and baffle plate under the screw tubes, then cover the front with a big deflector. Along with squaring the piston to the roof of the port, which I did on my JD CS56.

I did open the screw tubes to pass exhaust straight from behind the baffle. Enough exhaust puffs out of them that I think it helps while keeping the extra sound focused forward.

Lot's of overthinking goes into mufflers. LOL

 

[Nutball]

I'm the best at overthinking... I think.

My probably soon-to-be-ex GF would likely disagree...

 

[Nutball]

It's just going to take a shorter, and thinner, more flexible line in the tank with a slightly heavier oil filter to be able to reach around like it should. I hope Echo sees this.
