ECHO Echo, Echo, Echo

[LAWN BOY]

I picked up this Craftsman 2.7 just because I have 70cc version in the same colors. It was run maybe twice. It came with a really nice Oregon bar on it.

Nice, I have the same saw in Echo orange.

Ferguson, you ever run into Danial Boone or any of his kin? He was from Boonesborough aye? At least in the 1960's TV series.

'Fraid not, but been to the fort several times!

Echo 620/590 heated handle mod:

Good job echo, they built a deflector out of the thinnest sheet metal possible. Rather than welding the deflector in place, use a handful of tiny screws to hold this sht together. Presto: deflector cracks and everything rattles off. Blow a nice hole right through the brake handle and melt the top cover. Heated handles nice n toasty, melt the gloves off your fingers.

Anyhow, traverse creek sells a nice thick aluminum replacement. I used loctite 680 on all the deflector screws, and the base of the deflector. Little pricey, but definitely an upgrade from that tinfoil garbage it replaced.

Ouch! She got real toasty. After some solid run time the short comings arise. Haven't used my 590 enough to break it yet....except the time I launched it from the skid steer bucket into a stump...forgot it was there.
That's a nice looking replacement deflector. Let us know how it holds up.

Thedude74,
Yep, every saw has some little quirk that need attention. It sure is nice when the aftermarket offers an affordable fix.

Another echo saw with quirks: cs 8000 or 800p:
The carburetor is too small after porting the saw. The old 8000p carb fixes that purdy well.

Another quirk, the felling spikes are WAY too small for what you'd use an 81 cc saw for. Cutting down large stumps at ground level, the roots fan out at an angle where you're not even getting a bite with the uppermost spike. It's fatiguing and dangerous trying to keep that saw under control. I don't know what echo was thinking with those 50 cc sized spikes. They'd be useless in shaggy bark as well.

There's a fella on ebay who sells a good set for cheap. They're as thick of steel, as the felling spikes on my CS 1201.

Coupla hard years on the 620pw, was time to spin off that clutch and clean out the gunk. Grease that clutch bearing and replace that worn out rim sprocket.

Holy sht! A STEEL oiler gear.

Non of that plastic garbage that always strips out. What a brick-sht house of a saw. Love the filthy-good, indestructible METAL oiler gears on some of these echos.

Man, some of those metal gears are HARD to get off a crank after years of abuse! Lol
Some wear a Grove in the crank after years & years.
Vintage Poulans come to mind.
I had to heat one with heat gun recently because all the gunk had turned to glue.
That may be why some of the plastic ones work well enough until needing replaced.
$5 "consumable".

Metal ones are harder to find nowadays than plastic ones.

The 620's have a metal drive gear and a plastic oiler shaft driven gear, so the oilers themselves are the ones more likely to strip. Thankfully you can buy them straight from Zama, the original manufacturer of the oiler. The metal drive gear does not ride directly on the crankshaft--it has a plastic sleeve between it that is connected to the spanner that is fits into the cutouts in the clutch.

Cool.
The old Poulan's have a metal drive gear mounted directly on the crank to turn a plastic drive gear in the oil pump.

Yep, It's a smart design on the 620 oiler gear:
2 piece. The worm gear is metal, the little gear inside the oiler is also metal. But the plastic sleeve acts as a fuse.
Nother good one if u have the echo oiler gear removal tool and the installation tool is the metal worm gears on the later 6700/670. The install/removal tools work on the cs 530 and many others too. Just completely overhauled a brick sht-house cs 530 few days ago. And a 6700 couple months ago. Also replaced a melted plastic oiler gear on a cs 4910. Anyhow, here's that pressfit goodness on the 6700:

I think Husqvarna makes a tool like that for their saws.
From what I've read, they are pretty much universal with some persuasion.
My redneck rebuilds, its just a heat gun & screwdriver! LOL

 

[FergusonTO35]

I can see a 620 in my future for sure!

 

[mainer_in_ak]

Ferg,
Go for it! 620pw is my main squeeze. It's exactly 1 lb lighter than a full wrap 372 xp, but does all the same stuff as a 70 cc saw. That long stroke, aggressive ignition timing and aggressive port timing, it punches WAY above its 60 cc engine size.

I actually skip right over 70 cc stuff. When I need bigger, the 81 cc saw is what I grab: cutting large saw logs to 16-18 ft sticks, cutting down stumps and noodling large stumps or rounds that can't be split because of the knarly grain.

I also gave away all my 40 cc and 50 cc echos to family members and kids.

So the 60-67 cc saws with versacut 24" bars are my money makers. 2 60-67 cc saws are literally the price of one new 70 cc saw nowadays.

 

[FergusonTO35]

Oh I will, just gotta strike at the right time.

Save your money until Bruce puts them on sale again.
"Tweener" saw.

According to Mike Acres sight, the specs for the 620p are 59.8cc @ 13.67 pounds
Husqvarna 372xp is 71cc & 13.4 pounds.

My Driller ported 272xp is 13.7 pounds.
I have 3 Shindaiwa 695's @ 68cc @ 13.2 pounds.

Why bother with a 59.8cc if weight is a concern?

 

[FergusonTO35]

Price, new or used, for one thing. In any event, a 50+cc saw is basically a toy for me since I wouldn't use it much.

 

[thedude74]

At around 12.2-12.3 lbs the husky 357-359 and MS361 are pretty light for 60cc class. The 361, especially with a lightweight 20" ,feels lighter than the cs590.
I do really like the feel of the CS590....it just needs an 80cc top end.

Brisco builds some pretty spicy Echos. He pushed a 4910 to 7.4 HP on Joes Dyno.
