Husqvarna 346xp - At It Again

Hopefully everyone will check this description area before engaging the "yah see" , "what ifs", "I told you so" and general shudda , wodda, cuddas".....
1) In all reality, I am just a man.
2) A bunch of weights per cord of many different species were stated initially to get an idea of relative densities of some common firewood choices.
3) I measured this log: 12"
4) It's easy to see the wood has varying densities with the way the chain is grabbing differently as it is going, unaided, through the cut.
5) I miss quoted the 3rd run top rpms at 14,940 - really only 14,900. In the glare, it is hard to see the numbers on the tach readout at times.
6) And of course this saw is modified, but tweaked a little differently from the last run and the previous 346/550 shoot out video.
7) VARY rarely do stockers get a run and that is definitely mentioned if that the case.
8) Upon tearing this saw down, I found that the seizure was light and not from a lean condition. There is a slight casting flaw off to one side in the exhaust port. I suspect with the heat from the high rpms the expansion is different in the bore since the partial seize is opposite the casting flaw.
9) A new Meteor piston is currently on order.
10) This is the second rendition porting wise in this 346xp.
I am currently available for port work. If you are interested, please shoot me an email.

Thanks for watching.

Every so often I come back and watch this video and giggle and laugh at that little screamer. I love it. I’ve got a heavily used 346XP I got from a chainsaw carver. Well, if it ever pops I’m going to send it your way for a little hop up.

[@huckmiller1971]

Right here in polk Pa ! What a screamer ! I've never seen one turn that rpm before !

[@MrBucidart]

At 17560rpm I as was able to see an air gap between the top of the bar and chain, that's chooch'en...

[@speedandmarine9066]

If it was a lean seize it probably wouldn't have started again so soon or so easy. And even if it was, R&D testing is frequently destructive and part of learning. To all the haters in the comments and on forums bashing HOTSAWS101, get it over it and grow up, you guys should try acting with even half the integrity I see on this channel.

[@fabzacres-blackcat]

Speed and Marine I agree ... Jacks’ playing in his own sandbox just having fun ! Wtf with these haters ? Go back to your “forums” and cry about it ... Y’all sound like a bunch of old ladies at bingo night ! Better yet show YOUR SAW in operation - bunch of sour - grapes if I got anything to say about it !

[@stihlvarna]

For certain a lean seize. And it was apparent to anyone that knows how to tune a saw it was way lean before it even touched wood.

[@weberbuiltweber1908]

Your work and skills are admired by god on his green earth.

[@husqvarna3726]

That's awesome! I can't wait to see it break the 15k mark in the wood!

[@tristanburke2451]

I was waiting for the boom of the saw coming apart holyshit 17000 RPMs damn

[@johnlincicum6390]

This is why you are the king of insano-ized!

[@fabzacres-blackcat]

Correction ... Honda GP racers were 4 cycle ... the machine I was referring to was the RK67 50-2 made by Suzuki ... the RP 68 2-stroke triple (also by Suzuki ) was a 20000 rpm screamer !

[@buckbundy8642]

17,500?!?! That thing revs to the moon!! Hot damn! Can you give me an estimate to do this to my 346XP? I’ll email you in the morning!

[@keithmeier1824]

Just don't hit the rakers for a while, it'll get ya to 15,000 in the wood lol

[@susanagonzalez4886]

ijust got me a 346xp 50cc 2011 for 275 dollar you a very nice jod with those chain saw

[@dentondunn4346]

Was offered a 346xp with new bar & chain for me brand new 251c Stihl plus $80. Think I'll keep my Sthil with ithe 2 year earr7

[@ThomasBX88]

Hallo. Ist das die originale Zündspule ?

[@Fabzacres]

14900 verified .... can ya get over 15000 ? You might rabbit , you might !

[@Fabzacres]

That was verified by a measurement instrument ; it’s called a Tachometer ... now kindly run along and go play with your “wannabe - NEVER -be “ 261 chainsaw ! Lol 😆

[@scottybogs6895]

Wow thats some crazy fast RPM from a saw!

[@nkcwilliams]

Hey Jack, Great video. I have never seen a saw spine that high. Amazing. Thanks for bring us a long for your R&D. It would be cool to see a bench top tear down. You running stock bearings? Thanks Nick

[@jeffcampbell6314]

Yep, she seized right up.

[@chadrides914]

SKOOKUM !

[@danvankouwenberg7234]

I love mine. It's a little warthog. Bought it for $140 at a garage sale 😯. Just needed a chain.

[@colebones]

Just getting into cutting wondering what you find to be the best way to sharpen your chains.

[@hotsaws101]

colebones hi. If a guy can maintain the angles, then it's a hand file. The grinder if properly done with the angles set accordingly can be right there as well. Thanks for watching and blessing on this day.

[@BruceMyersLBZ]

@@hotsaws101 hey hot saws, wheres your shop located, you may b local for me? Titusville Pa

[@joehackett9471]

Holy RIPPER batman!

[@weberbuiltweber1908]

Whats your opinion on the Motul Grand Prix 2T verses the Motul 800 Road Race? Thank You for the very informative videos.

[@hotsaws101]

WeberBuilt Weber hi. It would depend on the state of tune and rpm range that the machine is working at - which is a load consideration. The insane-o SS saws are right at the limit between the off highway and switching to the roadrace version. I "wood" run the road race in the psycho and above saws personally due to where they operate in the rpm range while working. Thanks for watching and blessing for this day.

[@allenhuling598]

Cool...enjoyed that little experiment!!

[@richardclemence6287]

Where did you get the tach I’d like to get one!? Brand? Model?

[@hotsaws101]

Richard hi. I cannot remember. Pulse, PET-2100DXR. Might do a web search. Thanks for watching.

[@trentonsmith7513]

Holy Screaming, Batman!

[@arborist460]

Been cuttin walnut,locust,and white oak.....all great firewood...have some pecan too..

[@erichowes2531]

What was the purpose of leaning it out that much? Not bashing just curious

[@hotsaws101]

Eric hi. R & D requires extremes. Not sure where the notion of leaned out to much is coming from? Thanks for watching.

[@weberbuiltweber1908]

Is double the called for clearance about right?

[@hotsaws101]

WeberBuilt Weber hi. I cannot say that tolerances should be sloppy loose. Maybe a little bit more than "stock" but the stock range is huge so it would be a consideration of the individual saw and application specific. Thanks for watching.

[@captainsledge7554]

So what piston will hold up to this??

[@hotsaws101]

Kelly hi. The piston was OEM in the 1st go round and then I tried a Meteor. Thanks for watching.

[@adamsorell4851]

Is it same as husqvarna 55?

[@hotsaws101]

Adam hi. Not even in the same ball park. Thanks for watching.

[@kerrysaunders3685]

How fast will a stock saw rev?

[@hotsaws101]

Kerry hi. Depends. And it's on a few of the design & physical factors. There is no "x" rate for all saws. Some do it faster than others. It just the nature of how they come "out-da-box". Thanks for watching.

[@gerbutt]

Have you ever sent one of your saws overseas?

[@outinthewood3578]

I'm on my 5th saw from Mr B. 372XPW (75cc) 385XP 2x 562 XP/XPG and "375"XP. It's not a cheap exercise with the postage and tax/import duties so it would have to be a top class product to make it worth my time and very hard earned cash ! Most of what I cut is what we call "oversize" timber here, so to big for a 1470 JD or 951 Komatsu harvesters and to keep in front of them you need a couple of things and just one is a quick reliable saw and thats why I spend what I consider well spent cash with Mr B. If this sounds like an advert for his work then I suppose it is but thats what a customer that is happy with his purchase does ? There are many saw builders that build a fast saw and faster than some of Jack's but I tend to think that there are "fast" saws and "quick" saws. A fast saw is just that it's fast and will beat anything in a yard at a GTG it's well built but at work you ( I ! ) want a Quick saw so when you are clinging to a steep bank with the 2000lb harvester head above you pulling a big dirty Spruce in from a road side you are not thinking about how to feed the saw in the saw just works !! Jack falls and builds a perfect combination....

[@Fabzacres]

Yeppers ... definitely a BIG difference between a “cookie cutter” and a saw that slings a 32” bar as well as a 20” ... I have 2 saws built by JB ; a 241c “mighty mite” and just received a 461R a few weeks back ... I’m happy with the product ! What a lot of guys miss is that on a 2-stoke you tend the get “heat sink” which can reduce the power output by up to 20% .... a lot of Jacks competition make saws for the camera ; quick 3-cuts and shut-down .... Doesn’t really give a valid comparison imho ... if your saw cuts quick for 30 sec and then “heat sinks “ and you lose 20% power than what’s the point of having a ported-saw ? You may as well run a stocker ! I’ve cut many many cords with the 241c and about a dozen with the 461R and I’ve found Jack has the right combo of speed;power and “flow” such that the saw performs well over a days cutting from start to finish ...

[@gerbutt]

Thanks for the replies guys. I'll make it a mission to have one one day!

[@leonardvirtue5753]

WOW!!!😲😲😲

[@Woodman_Custom_Sawing]

Thanks for showing the good with ths bad. When you get it apart will you show us the damage? Take care and keep up the good work.

[@ryanbrown918]

I really want to see this as well. I've never seen a 346 turn these kinds of revs. Wow...

[@fabzacres-blackcat]

bobe8888 horse feathers!!!

[@fabzacres-blackcat]

bobe8888 I apologize in advance if you are hearing impaired sir but if not and you really listen to the saw in the cut it’s readily apparent it’s turning what he says it is ... in fact there is an app that measures rpm by sound to + or - 50 rpm if u STIHL don’t believe it ! Lol 😆

[@hotsaws101]

I pondered the commentary in this part of the thread for awhile. This saw will barely get above 15k free revving with the high speed needle bottomed out. And yes, it's on film as well. So,,, it's not stupid lean, as some would suggest, anywhere in this video. I find the observations from 1500 +/- miles away interesting, but not accurate. Already mentioned this but again, running the second piston here which is how I know the problem is on the drive side in the exhaust port. The cylinder wall suffered on the drive side from the oem piston failure. The oem piston melt down was most likely from the casting flaw in the exhaust port causing uneven heat expansion in the cylinder wall itself. It was below the surface until the grinding happened. It happened the exact same way as the Meteor piston in this video. R & D. Mr. Speed spells it out. My suggestion is this: When he talks, others would do themselves a big favor to listen. He is way smarter than I. It's too bad some guys just shoot from the hip, with nary a question.

[@hotsaws101]

Ryan hi. I would be very leery of some of the commentary and research the topic well. Agenda is prevalent and skews the commentary. Thanks for watching.

[@erichowes2531]

Any update on this little guy?

[@hotsaws101]

Eric hi. The reader card had some issues and I am going to have to splice two videos together where neither one is complete, which is a bummer. The cylinder was pretty trashed from the 1st and 2nd piston meltdowns so it did not do what I had hoped in the 3rd run. Thanks for watching.

[@nugraha_copycamshaft6495]

That. Setting for 4 stroke tacho

[@weskerlion3260]

346xp extreme 17,560rpm chool alto desempenho para baxa cc,.

[@antoniofeio5304]

Já vio giro igual a esse amigo 14 mil rpm na madeira tá doido dúvida nessa categoria de cilindrada ter uma pra enfrentar essa máquina

[@colmhick]

never seen the wrap handle bar on a 346 before.

[@hotsaws101]

colmhick hi. Made 'em all buy myself. Thanks for watching.

[@Mikzone-zb6jk]

Lord have mercy!! Lol

[@chasemcmann5930]

Awesome I would love for you to build my 562xp how would I get in contact with you to do that

[@chasemcmann5930]

Brett Black thank you

[@weberbuiltweber1908]

Its seems just a little more bore clearance is all that saw needed.

[@hotsaws101]

WeberBuilt hi. There was a casting flaw in exhaust port at about 10 looking down. I think it allowed for uneven expansion at the high revs and the bore became elliptical. The first two pistons scored in the same way/spot. By the time I cleaned up the cylinder twice the tolerance was getting pretty loose. The 3rd piston scored the same as the 1st two + more across the front. I actually had shut the high speed needle down completely at one point just to see the outcome. It would barely run - what you would expect when not getting enough fuel. The third melt down looked more like an unloaded over reving issue. Thank for watching.

[@weberbuiltweber1908]

Also castor is safer for extremes. shure not cleanest though.

[@SMJ95]

Bitchin!!

[@Gunnypauly73]

3:03 BOOOM ! She's a little lean

[@weberbuiltweber1908]

You may want to add a little more oil in fuel for extreme rpm. In some research I did a while back, rpm goes hand in hand with oil ratio.

[@fabzacres-blackcat]

Some info some may find interesting - RC car with a 4.6 cc 2-stroke single cylinder burning nitro-methane hits peak hp at a staggering 35000rpm and can rev even higher to 39000rpm ... ask me how I know lol !

[@anatoliyang546]

Very easily you look at the spinning wheel RC car and count rpm.

[@shaun4bigblocks993]

I am assuming the decription #10 "second rendition" means a 50cc cylinder? You should not wait until the end of the description to mention a key modification and until the end of the video to mentio. "Meteor" aka after market top end. Also, people have to stop with this "346 XP" crap- either put "346 XP OE" or "346 XP NE" and give it a proper identity unlike a noob...

[@weberbuiltweber1908]

And more oil also drops octane so race gas should be used for extreme rpm and high oil content.

[@weberbuiltweber1908]

Was thinking more clearance but its more oil and that means more gasoline. Try the 25 to 1 bet will make you say damn.

[@garybenedict3673]

Tell that’s not entertainment

[@NathanVdV]

to bad people want to find extremes on their machines. why go to 17k rpm when 15 or 14k will do just fine.

[@buckbundy8642]

Nathan Van de Velde because it’s fun.

[@weberbuiltweber1908]

Not sure why you came at me cuz I spoke on wrong video. Your work and skills are great but will tell you again no matter quality of oil 40 to one is no good for extreme rpms. Every addition of rpm takes more oil.

[@bill154cub]

Beaware when I guy shows up with a 1/2 ton truck selling you a cord of wood. I seen one guy with a one ton dump saying it’s a two cord load. After two loads it stacked three cords when it should of been 4. Beaware of the dry wood cord weights.

[@bill154cub]

I could fit 1 1/2 cords safely in my one ton truck. I went to the local gravel pits and came out weighing 15 k with a load of 1 1/4 stone. The truck felt the same as hauling green oak.

[@bill154cub]

I figure green wood one cord is 6 k wet.

[@bill154cub]

Oh no seized. Riches the oil more.
