ECHO Echo, Echo, Echo

[Mastermind]

Howdy I'm new to this thread but I'm enjoying the content. I just bought a 650evl at a pawn shop. It was marked as a non runner as-is. I figured it was worth $50 for the cool factor. As with many pawn shop as-is "non runners", it runs.lol At least, it starts. I'll look through it before I try to cut with it. Quite undeliberately, I'm amassing a very small vintage saw collection. Olympyk 999f. Stihl 056, 041, and now the old Echo. I have a few old Homelites as well but they're a dime-a-dozen around here so not very exciting.

I've been intrigued by the Shindaiwa/ Echo affiliation mentioned here. I have a 22t Shindaiwa weedeater that is nearly 20 years old and has been a joy to own. I'll be watching for some of the pre-merger saws mentioned here.

Good old saws....not exciting to run, but well built.

Can anyone help me locate an air filter and air filter cover for this 50V?





Thanks,

A quick note on the Tecumseh engines (per mention elsewhere) They always had an appetite for exhaust valves and were prone to slinging the internal governor weights loose.
Ever notice the push mowers that over revved and then bogged in the grass? Yep usually a Tecumseh with the governor busted. If the muffler looks like it's had a torch inside of it, the exhaust valve is starting to leak. Runs about 15~20 mins and looses power? But runs again after half an hour~ish? Muffler look cooked? Exhaust valve is leaking.
The governor flyweight chunks could end up taking out the cam gear teeth if you just kept running them after it broke.
I wish Briggs ahdn't gone to that internal governor, as I see their mower engines over reving now.

Same as Echo 452vl but you probably already know that. More than likely a few on the Bay.

Edit, I checked, there are several listed for the 452vl on eBay at the moment, I believe the 451vl is also the same.

mowerman2 - message received and I've sent a reply.

old 040 - thanks for than information. I am not very familiar with the Echo models so any help is appreciated.

I was able to find a Service Manual that includes an IPL covering the 351, 451, and 452 VL models so that should be useful as well.

I'm sure you've thought of this. To make it operable, a piece filter material cut to size and a piece of wood cut and drilled for a cover would work. This obviously wouldn't "cut it" for collectors piece purposes.

FYI, the foam precleaners for many Briggs engines are an excellent material for cutting your own air filters. You can also use the material to repair NLA filters that can't be easily fabricated.

Looks like you'll be in need of the grommet for the carb adjusting screws as well.

I found one place on line that had everything listed (AF, cover, grommet, starter bushing) and placed an order....they refunded my payment a short while later indicating they didn't have any of those parts and could no longer get them...

mowerman is checking on a few bits, I did order the mounting bracket (protector?) off eBay. I'm thinking/hoping I can find or make enough parts to get this saw operational again.

Here's a clean original 452vl I picked up recently, the red top 031 was also a recent grab.....

Hello, long time lurker--first post about my own saws. Back in 80's I worked in small hardware and learned small engine repair. My first chainsaw purchase was a traded in cs452. Over the years I've bought and fixed up several in different colors. I finally got around to fixing up an 452 with an interesting chain brake option. I think it was echo's attempt to add a chain brake without redesigning the whole saw. Just change the sprocket and add a brake in the side cover. I have a similar setup for a cs302 but I'm missing the sprocket. Now I have several 452's: 2 echos, a craftsman version, and a john deere version (that usually rides in my truck toolbox). I have some newer saws but prefer the older echos--I just like they way they are built.

Is it JUST me or is an Echo Bow saw uncommon? OR is it an option that will interchange with other Brands? I seldom see bow saws here in Nebraska. It is an attention getter.

 

[mowerman2]

I think it is uncommon. I was curious about bow saws and got one. I had to use a spacer on the bar studs, but the oiler hole lined up fine. It worked great for cutting up logs lying on the ground up to 8-9inches. No bending over or kneeling; much easier on an old back. It was easy to not hit the dirt as well. I have heard bad stories about kickback so I tried to be careful. I did have to experiment with drivelink count for the chain.

Your story sounds very similar to myself. I also started my first "real job" at an old hardware store that also had a small engine repair shop. Although my first real saw purchase was a Stihl 030av that was traded in. It was completely torn down and gone through before I bought it. I paid $165. for it back in the early 80's which was a lot of dough for me back then. I really liked the saw and have since bought another clean 030av just to have. I never see the Echo's from that time period with a chain-brake set up like the one you have in my area. I do see them occasionally go through eBay....My current 030av..................

Just about got this torched qv 6700 overhauled.
New impulse, carb boot, bearings, seals, piston, cylinder.

Carb rebuilt, ignition advanced, muffler opened up, base gasket delete. Plastic oiler gear upgraded to brass, case halves and base sealed up with echo 1207d sealant.

Anyhow, this 6700 still comes in $130 cheaper than a new 590. I'm going to compare the two. Which pro-grade budget saw will cut quicker? Does a newer 60 cc equal older 67 cc?

How will these compare to a stihl ms 362? The ms 362 was more expensive than both the 590 and the 6700 combined.

Any predictions?

 

[mainer_in_ak]

Round 1 goes to the 590 timberwolf. With the increased compression, the 6700's clapped out starter recoil finally let loose. Snapped pawl off the flywheel when it grenaded. Flywheel fins are OK.

Haha, old saws, didnt even make it to the starting line! Waiting on a fresh recoil and set of pawls.

 

[nbbt]

The 590 in my collection has only had a exhaust (muffler) mod. added. As others have said b4, this was choked down from the factory.

My recent CS-400 runs really well even with the cat muffler. My biggest concern is having all that heat next to the cylinder, seems like that would not be good for engine life. At the same time, does the constant outflow of exhaust carry the extra heat away? Automotive cats don't cause any problems unless they are overheating or clogged and I leave them in place unless they cause problems.

Cars don't run 13k + rpm with a splash of oil they have coolant with radiators and oil sump circulating oil around all keeping the temp well regulated. A saw gets a splash of oil mixed with gas and a fan that's it. No need for a cat just holds heat
