[@TheGuitarRoom]

It’s amazing how many people have starting issues with Husqvarna’s and how many people have starting issues with Stihl. I genuinely think with either saw it’s all in what gas you use, what mix, how are you maintain the saw and if you follow factory regulations and guidelines for hot and cold starts. They are two cycle engines at the end of the day and they will all get temperamental. All of them. In my experience, having both and having followed the factory guidelines as well as running my now Husqvarna saws along side of Stihl’s, I can say that hands-down my Husqvarna saws never have starting problems. They are newer than older saws and I have been exclusively running Husqvarna premixed fuel and following factory guidelines. Never had any issues. Not one. It’s more expensive, but between the premix fuel and the meticulous maintenance adding in the factory guidelines, that should eliminate starting problems for both saws

[@Omegadoomship]

Running ethanol free gas is an absolute must. As a small engine mechanic, I try to sell people on the idea that mixing fuel is a thing of the past unless you mix straight ethanol free gas with high quality 2-cycle oil. Using the cheap Echo 2-cycle oil will clog up your muffler eventually. It doesn’t burn as cleanly as a high quality marine 2-stroke oil. Even though ethanol free gas helps with reliability, that doesn’t mean that it will make the cheap brands any better than they are. I tell customers if your going to buy a 2 stroke, get a Stihl, certain Echo, and certain Husqvarna. Red Max, Kawasaki and Shindaiwa also get a pass but they aren’t as common in my area. Everything else is junk.

[@TheGuitarRoom]

@@Omegadoomship Preach it brother. I won’t use anything less than 95 Ethanol free octane if I am going to do my own mix, and I will exclusively use Husqvarna oil. I’ve actually done my own experiments. To me the Husqvarna oil is far superior. However now I stick to premixed fuel as I’m not running the machines all day, every day. My 12 year old Stihl BR 600 is the only machine that I mix my own fuel for. The rest is Husqvarna premix fuel. All my machines run like new.

True to form , Husqvarna tends to out pace the Stihl in power and in tork . With the MS design you will loose some power at lower RPM and with the lighter crank in the these newer models you have less low end tork . Your power is solely made by high RPM with a limiter on the stock coil. Both Husqvarna and Stihl are great Chainsaws it's just how strong of saw do you need and how dependable.

Husky 592 better and win💪💪

[@nighttrain022]

Very interesting. I would have expected it to be like this except my guess was the 2 newest saws would have highest due to their engines having less wear. I'd be curious if we had essentially an even playing field. New top ends, carbs, air filters everything as if all 4 just left the factory.

[@dynojoemods2764]

The brand new saws are the most disadvantaged, full break in adds a bit of power from brand new. 2-5% in some cases. The 592xp and 395xp this was the fort time being fueled. The 661 has very low runtime. The 660 has the most run time, but still a very sound saw.

[@Rein_Ciarfella]

Dyno Joe Mods Is that additional power after break-in due to rings seating or something else?

[@dynojoemods2764]

@@Rein_Ciarfella The 2-5% I mention above is because of break in.

Thank you

[@tonytribisonna9886]

The 660 & 395 have proven to be strong and reliable saws. Not that I can say the same for 661 they haven’t been reliable as the 660. I hope the 592 xp will be as reliable as the 395 I’m very impressed with Dyno figures 592 Like your reviews 👍

[@hbhb8173]

What’s going on with the 40 to 1 Husqvarna other fuel is 50 to 1 and this is what I have ran for ever just wondering your reasoning

[@dynojoemods2764]

In the modified saws I just like a little bit more oil. It really helps the late model saws with the air injection/ strato ports.

[@kevinbrewer9421]

Now put a 7 pin sprocket on that 661 see what that dose !! You might be surprised.

[@andrewotero1972]

I was really hoping the 660 pulled out a little bit better I was rooting for old school!! I port alot of saws my 660s And 395s are always good runners Haven't got my hands on a 595 yet interesting?!!

[@heily-3806]

661 is too choked off at the factory to meet stripped European emissions. It needs a muffler mod and a little bit of work

[@justinweaver8787]

Shocking!!

[@josesalvi23]

La MS 660 es la mejor de las 4 en durabilidad. Fin

[@smiley454jmw]

Dang i always thought my 660 had more low pulling torque than my 395 like grunt power just know my 395 cuts a lot quicker thought it was just due to the higher rpms that the husqvarna turns vs the stihl i normally run either a 28 or 32 bar on them 36 if i have to but no matter bar size the husqvarna always cuts faster but just sure pulling power the 660 seems like it might have an edge over the husqvarna

🤤🤤🤤🤤 love this is

[@joschmoyo4532]

It's a bit like comparing Kawasaki to Yamaha. Sure the Husky may give you slightly higher numbers but reliability and longevity forget it. Husky burned me twice and I will never forgive them. All my Stihls are still running, still starting easy. It's a no brainer. Tear apart a Husky and you will see why they don't last. They look pretty on the outside but single piston rings are harder on bores that are only single nickel plated. Husky cuts corners faster, that's all.

[@mmholling87]

Technically a single piston ring would cause exactly half the wear of two rings but in reality the bore is much harder than the rings.

[@joschmoyo4532]

@@mmholling87 A lot depends on the metallurgy. Chrome nickel bores tend to be less prone to peeling than straight Nickel. Two rings in theory will have more friction than single rings but hold compression better and trap lubricant better. Husky bores are prone to casting voids that cause failure and even when you can prove it's a production fault they will not cover it. So Husqvarna got to screw me twice but never again.

[@benharman3003]

I killed 7 saws commercial felling. Run 40:1. 5 stihls all melted piston skirts. 2 Husqvarna shit a ring Husqvarna for the win I say... Wayyyy nicer around the base of a tree than ya stinky stihl. No saw likes to be overheated so balance and torque is the question of who wins

[@benharman3003]

Husky has a bigger crank too lol

[@joschmoyo4532]

@@benharman3003 Interesting. I will say this. The Stihl air filters do need cleaning more often, they do bog up faster. The lack of scavenging air in the filter box is unfortunate. Husky beat them to it there. We all know how quickly a bogged up air filter can screw your engine. I don't run my oil 50 to 1, but I don't mix it to oily either. I never use any two stroke oil other than Stihl ultra. Other oils have let me down. Another fatal mistake that can lead to overheating is to little bar oil. Back in the eighties Husky made good tough saws but those days are over.

Pls. Stihl ms 390 Stock end muffler mod. Thank you freind

[@steppoffaith8426]

396 was not tuned at all!

[@dynojoemods2764]

What was wrong with the 395 tune? That one is on par or slightly better performing than all of the other 395s I have tested.

[@steppoffaith8426]

@@dynojoemods2764 not 1 of those saws.work in the real world in the 6k,7,8,9k range. rpm range. The 395 needed leaned out little more for my tast. I own 3 of them i work them in the 11k range they are happy with tons of pull. I have 660s that lay down in the 9 to 11k range. So my experience with saws in the wood making hundreds of cuts is almost opposite your analysis.

[@dynojoemods2764]

@@steppoffaith8426 The 395 was tuned close to 12.5k maybe a tad rich still. But 395 stock won't hold over 12k in the wood bar buried.

[@Brian-Outdoors]

Torque must be all that really matters as my 395XP cuts faster than my buddies MS661. Just picked up the 592XP yesterday so can’t wait to see it really dominate my buddy’s Stihl and send him home thinking😆

[@dynojoemods2764]

Chain is the biggest difference maker. 1 swipe different it may favor either saw. Hope the 592 works out well for you. It could be a very nice saw. Time will tell

[@Brian-Outdoors]

@@dynojoemods2764 I agree that all these saws are all so close that a sharp chain is all that matters. I just like firing up the Stihl fanboys😀

why is husky always stronger than stihl? and I really don't get it, how does a friggin 90cc 2 stroke have this low power? a 82cc dirtbike has like 30hp

Saws are designed to go 100s of hours meeting emissions and warranty requirements. Vs all out race bikes that habe short rebuild intervals and expansion chambers
