Stock vs Ported | Echo CS 4910 Chainsaw

[@JohnSpaulding]

That is absolutely unbelievable. I worked for a small engine guy and he told me back in the early 90's that engines come with about 50% of their possible power. He would port, polish, headwork to gain more without the decrease in reliability.

[@mauricedubeau3247]

You've got that receipe dialed in on the Echo CS 4910's,,,,, Nice work on the port job !!,

[@KNLFirewood]

That is a nice saw now! Best part when you said “…it didn’t like that at all.” 😂. Great work as usual. I’ve only watched this about 10 times…

[@902hand7]

Man that was painful to watch stock but dam did you ever make it go fast after working your magic on it. Great work Charles!

[@sunbear1973]

Yep, like others have said “you are the master with the 4910”. I would love to have one of your ported saws. One of these day I will have to buy a 4910 and see what I can do with my shade tree mechanic skills. Lol.

[@chrisjacobs2182]

Great job huge gains you're a master at those 4910s!

[@rodneykegley6948]

You are the master of Echo 4910 porting

[@Duanepa.2]

Nice work! That is a dandy firewood saw now that you worked it over.

[@oldcodger1929]

Nice job. You took it from a dog to a usable saw.

[@Woodman_Custom_Sawing]

Personally I'd keep the 325 pitch on it but very respectable improvement.

[@Houseworksaws]

Man if it were only that easy.. 5 second porting break lol 😆.. The magic of television

[@justinweaver8787]

Holy crap night n day different huh WOW!!!

[@lonnieholbert8898]

Ive got a Husky 50 rancher that I put a big bore kit on that Im hoping to get the exact same results with. The numbers on the cylender are pretty crazy though. 110 ex and 68 in.

[@Cholton222]

Holly hell dude. Awesome cutin saw

[@joehackett9471]

Id say that saw woke right up!

[@Doc-Cole_Trickle-of-Chainsaws]

👍🆙CB, what is the stock blow down on the 4910 and where does it end up after porting?

[@crabmansteve6844]

Damn dude that's awesome, that saw was AWFUL when it was stock. Lol

[@Sawmods]

Im so torn between a 4910 and 550xp. Ive got several big ported saws but i need a 50cc lightweight saw my old 951 olympyk just aint cutting it but cant decide which one i want to play with. Hell sometimes they dont even see wood before I port them. I would love to know the port numbers on that mean 461 of yours. Ive got the 2 port stuff down to a science but the long transfer is kinda new to me.

[@CharlesBrisco]

550 is faster out of box but it prolly crap out the crank barrings 4910 ported is sweet an very durable

[@travisweldmaster7815]

Yeah man shes pissed off little rig now nice bud

[@backyardfirewood9852]

That’s just just crazy!

[@chrisseger6870]

You do great work! So do you machine it also, or strictly port? Either way, great job.

[@CharlesBrisco]

Cut the base

[@roostercoggburn7436]

Wow! That thing rips now! Have you tried porting the cs-490? I'm interested in trying to port my 490 and wondering if similar results expected? Thank you for the great videos!

[@CharlesBrisco]

Yep they gain good to just not as much as 4910 but shud be able to get 4.5 to5hp out of one

[@roostercoggburn7436]

@@CharlesBrisco Nice, do you have a go to recipe for timing numbers and squish I should shoot for? Looking for a good reliable firewood saw.

[@CharlesBrisco]

@@roostercoggburn7436 20 sq 102ex open lowers up good 80 on intake same muff mod as I do on 4910 shud be sout saw

[@roostercoggburn7436]

@@CharlesBrisco great! Thank you very much for sharing the recipe. I'm excited to try my hand at porting. Just really getting into digging deeper into my chainsaws! Hope Tucker is doing well, have a great weekend!

[@BigAgitator]

Wow!! Now I know why people rant and rave so much about porting

[@hastonandrew2]

Wow it woke that saw up

[@notyourpapa]

Wow that is quite a difference. I'm thinking of picking one up because of the price. Any interest in sharing your numbers?

[@CharlesBrisco]

I have lots of vids on them an what to do

[@austinmarcum5338]

How do I get ahold of you about getting a saw ported?

[@CharlesBrisco]

Face book messager but I can't take work.on right now I have my hands full taking care of dad at the moment

[@austinmarcum5338]

Alright understand completely

[@crazyfeller5704]

👍

[@Dolmar-Rick]

that one seemed piss poor stock. normally better than that, i guess it is 3/8 s and cherry can be pretty hard. I guess wasn't broken in and sounded very rich. Nice job on porting as usual though👍

[@CharlesBrisco]

It was the lowest power stock one I've ran into yet not sure why

[@Dolmar-Rick]

@@CharlesBrisco yeah was strange. Did you tune it before running... it did sound as tight as a duck's a$$ though😂

[@CharlesBrisco]

@@Dolmar-Rick no I was on a time crunch I swaped it to 3/8an did to test cuts then ported it

[@JandSChainsaw]

Nore than likely the next saw u buy honestly never owned an echo

[@hillbilly4christ638]

This is so disgusting. The epa has really restricted the industry. My father used to say regulation costs money. For real! Just think where we would be right now if we didnt have the restrictions. Cheaper, more reliable, more power and more user friendly saws.

[@UntouchableSavage]

OMG I WANT PORT EXHAUST ALLLLL ALLLLL MF ON MY 2008 MF 20in MF POULAN PRO 46cc

[@slaxxx]

Man they are terrible stock
