I just want to say, I gain so much value from your content. I'm not a saw builder but I do like to tinker with them and watching you work and hearing you talk about them with such clarity makes me understand saws so easily. Please keep up the good work! And I think I'm sold on my next 50cc saw.
Awesome vid! Echo saws seriously underrated because they don't have the same name or scream like the other two majors......but last for ever and responsive to mods...u bet! Great work!
I was cutting down a 30 inch diameter tree down I was disappointed at the CS4910 bogging down . It is brand new. After some change with chain tension and use a flat screwdriver to enlarge the deflector Hole by flattening the exhaust tab The saw run better . I’ll try again by removing the restrictive tube Thanks for the video . So far 1 gal of mixed gas thru the saw. It is good saw for $350 Hopefully the exhaust mod will add power
They sure haven't dropped in price that's for sure. I paid 379 at Home Depot for one today, $400 out the door. Seems like 3 yrs after your video you could get them cheaper. Oh yeah price inflation. Lol Cool video, subscribed, I'll definitely have to do a muffler mod on this thing.
@@mweba1 I agree. My current big saw is a MS290. I'm 67 years old and started a Solo Tree Biz in March. My biggest tree trunk was 36" so far. I'm gonna replace the ms290 with the 4910 with a 20" and add a 620P with 27 or 28" for my new biggest saw. I'm looking for to the decompression release on both saws.
On the Echo cs-4910, if you remove the inner guide plate is there any small part that’s behind it? I took mine apart to clean it and now the oil runs out like crazy. I’m wondering if there was a part behind that guide plate in the area where the oil comes out that I lost so never got put back.
And, I know you probably don't get paid enough from youtube, and this is only a little 50 cc saw, but you should do (please) a porting video, and carb mods too - for the regular guy, like you did on the big echo with the epoxy in the transfers. You don't epoxy these non-cap transfers do you? These little 50cc saws, though a little slow, will definitely put wood on your truck, and don't break your back (though you might need to lean due to the short bar). But, go for the smaller wood aye?
If I can find time, it will happen. Time is something I have trouble finding these days... If I do it, it will be a full woods port with chamber mods. Not something most people can do.
I purchased this exact saw last week. Brand new it fired on the 4th pull. Now, wont fire at all after the first tank of fuel. Just floods. Using trufuel 50:1. Have you heard of any issues or did I just get lucky enough to buy a defective one?
I just bought one and learned that if you do not pull the throttle trigger the choke will remain on...even after pushing the choke in...you may already know this...
how are the transfers are they the same as 501p? or do they do the husq trick of detuning with smaller transfers? looks like it would be harder, as there are no caps and they would need a completely different cyl. I love how light they are, even with the plastic bars. And, longer break in is true. 10 tanks maybe? I know you can just look and tell, because you have done a million of them, but if you are just moding the muf, open up the hole just a little more, and a lot more on the deflector, and they run great.
Exact same crank case, crank shaft, carb, piston and cylinder. It's a 501P with a plastic handle, plastic rear handle grip and possibly a different coil.
You seem to have a lot of experience with these saws. I have a 501p that I've run for the past year. Its filter seems to get excessively dirty. Usually by the 3rd tank I'm loosing power and have to swap filters. I cut a lot of dead dry and dusty oak which i know contributes to the issue. I also run an old cs400 a lot as well through the same wood but I've never have an issue with the filtration system clean it once every week or so and its good to go. Is this a problem you've encountered by any chance? If you have any suggestions on how possible fixes I'd be very grateful. Love my 501p but getting a bit tired of having to clean out a caked filter every time i use it.
Ditto. I wish they would have kept the old round pleated filter like on the 400 and 370. If you look at a Shindy 488 it’s the same kind of filter. Basically after the merger with Shindy these style of filter came on the 500,490 and the 590 saws. They have reverted back on the 7310 to the pleated filter. I’m hoping for a new version of 50 and 60cc saws based on the 7310. I use a foam pre filter from the chainsaw guy on mine. It saves my filter from almost all of the dirt.
Same here. I use a foam prefilter on mine for ease of cleaning. The chainsawguy is where I got the prefilters. He retired but I think you can get them from the Myrtle Creek Saw Shop where he worked.
Hey brother Ive watched you for some time. I got a 4910 didnt need it but 490 no comp release. I havent even fueled up. Will put VP 50:1 I get good price on it.PS are those capture nut clips worth $14.00 or so??
I have a question the echo 620 and the Shindaiwa 600sx are they one and the same, I like the reviews on the 620, however I am partial to red and black, miss my Jonsereds I guess, my question(s) are would a full wrap from a 620 readily mount to a 600sx, also does a good woodsport and muffler mod really.wake these saws up, lastly you don't see alot of attention or love given to the Shindys is their a reason, and your thoughts? By the way Ann is my significant other, my names Rick. Excellent videos by the way!
Personally haven't tried to swap them but it is the same platform so I see no reason parts would not interchange. Shinny saws are not common in my area...
Pretty sure this whole family of saws is based off the Shindaiwa 502s, which i have, that never made it to US market. Its like a 10 year old family of saws.
Aside from the CC difference, which do you think is the better built, more reliable saw - this CS4910 or the CS590? A 50cc saw would be fine for my needs, but the 590 is only like $40 more at my local dealer. Hard to pass up if it is the better saw
Is this the same as the Shindaiwa 491s, and echo 490? Just a new badge? Same plastic clutch cover, only has 1 felling dawg. Same filter, belive same hp numbers. Pretty light good saw. Great 50cc if you're on a budget. 261c eats it's breakfast, and stomps it silly.
My local dealer sells them for 325 plus tax all day. I don't run them but we picked up a couple for customers. Very tame stk but ran good after porting and machine work.
I bought the echoes 400-18" they are all defected ,I tried 3 differnt once and each one leaks chain oil new out the box when you worm it up for 5 minutes, just idling Leaves a lot of oil on the floor with out useing or spinning the chainsaw...do you know anything about that? I returned them all.....I'm willing to try this one since it's about the same weight of the 400 cs....does that one gush oil out when idling ?
The cs400 has a worm gear pressed onto the crankshaft. When it's running, it's oiling. The saws were not defective, they were let to idle to long. Cs4910 has a clutch drum driven oiler. This saw only oils when cutting.
@@mweba1 ok since you know more about chainsaws then I ever will, 4910 it is now just gota wait for it to reach homedpot shelves....thank you for your help...
@@mweba1 I just look at the 4910 compared to the 501p and know my local customers would have a hard time getting behind the 4910 because of the extra plastic parts. Too bad the metal handle is half the money you would save by going with the 4910

I was cutting down a 30 inch diameter tree down
I was disappointed at the CS4910 bogging down .
It is brand new.
After some change with chain tension and use a flat screwdriver to enlarge the deflector
Hole by flattening the exhaust tab
The saw run better .
I’ll try again by removing the restrictive tube
Thanks for the video .
So far 1 gal of mixed gas thru the saw.
It is good saw for $350
Hopefully the exhaust mod will add power
Let it break in

Sure nice to see a rim setup. Sure likeslike a true pro saw design compared to former offerings.
The saw is awesome and it helped me when in need without any hesitations.
I ported mine an gave it a duel port muffler job best bang for your buck in a 50cc saw awesome little saw
Yes sir. I watched them all. Runs good. I've been recommending the 501P for years. Now that it's remarketed as the 4910 at $100 less, no brainer.
Very informative vid. I'll be getting a 4910 soon. Thanks
Great tear down man👍🏻
Now I want one for sure! Thanks for the video.
Muffler modded, it's still just a hair behind the 550xp but for under 350 out the door, there is no better saw.
@@mweba1 Master, at what compression does the saw begin to lose power?
@@Sensei948 Depends on the saw but 120 and under would be a noticeable loss of power.
great job...great vid
Great, informative video. Thank you!
Great video. The coil is not the same. Just checked on my 501P, and it appears white and different than the 4910 in your video.
Great video. Would really appreciate a video of how you ported this saw. Love my Shindaiwa 491, but I’d like to see it run like this!
If time allows. I do a couple things that no one else is doing so it would be difficult to replicate.
@@mweba1 Master, can you pour 33: 1 husqvarna ls + into the saw 372xp 357xp and scythe 545rx? Will the piston rings get stuck with carbon?
Great video and now I'm thinking of buying this over the 501P
Unless you need a metal top handle, I see no reason to buy the 501. $13 for the captured bar nuts
@@mweba1 I agree. My current big saw is a MS290. I'm 67 years old and started a Solo Tree Biz in March. My biggest tree trunk was 36" so far.

@@mweba1 I picked up a new CS4910 today and they ordered a set of captive nuts for me.
@@Billster1955 Good value in that saw. Pull the exhaust restricted tube and you're good to go.
@@mweba1 will do, thanks.
good job fast and to the point
Atlest I've been super happy with my echo saw.

@@mweba1 yeah bring on the full porting video !
@@mweba1 Thanks! And, thanks for all the info about these saws.
I wish we could get the shindaiwa version in the US. I like the red scheme better.
I got the shindaiwa 600sx because I like the red w black choke lever.its same as echo 620p rated 3.3kw power. Very smooth saw.
Seems like on manifold restricter they would have configured to to introduce swirl . i take it you removed restricter
Remind me of my dad, guy writes stuff down on the walls or bench lol

What size bolts are the two in the middle exhaust ? I know the bottom two are 4mm…. Trying to take off for first time. Seems to be frozen or seized
THE Correct ORANGE colored Saw. Ha
Been wandering when you’d do
A video on this. Is the bolt pattern for the handle the same as the 501p aluminum handle?
Yep
Pretty sure this whole family of saws is based off the Shindaiwa 502s, which i have, that never made it to US market. Its like a 10 year old family of saws.
Also Shindaiwa 501sx in AU and EU and Japanese market Shindaiwa E2050DS
is the crankcase magnesium?
Yes

590 seems more powerful to me.
I ended up getting the 590. So glad I did.
Nice saw, what's your input on the 3510 and the cs400
Ordered a 3510 so keep an eye out.
Hey, did you have to do any tuning after doing the muffler mod? Thanks.
Where's this echo saw made at?
Do you think the power difference is worth spending the money on 501p if you dont use everyday I carve but not everyday
Nope. The difference is power is almost not detectable.
Cool thanks for the response enjoy the breakdowns made my decision easier keep it up man helps alot
Is this the same as the Shindaiwa 491s, and echo 490? Just a new badge? Same plastic clutch cover, only has 1 felling dawg. Same filter, belive same hp numbers. Pretty light good saw. Great 50cc if you're on a budget. 261c eats it's breakfast, and stomps it silly.
It's a 501P rebrand.
What chain did you put on there? I am going to mod my muffler tonight and throw a good full chisel on it
where can I buy this saw under $350 ????, I can't find any one around me that has them--thanks Gary
Sawsuppliers in wisconsin
My local dealer sells them for 325 plus tax all day. I don't run them but we picked up a couple for customers. Very tame stk but ran good after porting and machine work.
how much$ and where did you get saw? still cant find them
Sawsuppliers has them in stock. Use promo code chainsaw repair
@@mweba1 Cant find them in New England at dealers anywhere. Just ebay for almost $500.
magnesium crank case on cs4910 cs501p?
you say yes at the end there ...i realized the other channel didnt atually say
@@enginnerdedtohoopajoop4604 Yes. Same case as the 501p.
Are you an Echo dealer?
No. I do all makes and models. Echo just released several news ones so that's the flavor last couple months.
