Just another junk chainsaw

Then stihl carbide chain, I swear no stopping it. They say 4 times longer cutting. IMO much much longer then that.

Highly impressed. Was shocked by it how well they hold up.

It still dont need a touch up.

A few years ago my mother asked me to cut the top off an old maple stump so that it would be easier to mow around. Instead I decided to rake it out. They wanted $300 to grind it which I thought was reasonable since they have transport and setup time, but decided that a new chain was cheaper. I put an older chain on, dug around the stump then started cutting. It took about 1/2 hour and the way the smoke was pouring off the chain I thought I'd need a new bar but it held together until I got a chain around the stump and pulled it.
I then took the chain off and threw it into the trash.

64cc poulan 4000.

Guess I didnt post it here. This was with a regular chain I sharpened that was a chain I pull from stuff coming in that I wont use for regular cutting. I call them my crap chains for root cutting. 70dl set up.

Ended up ordering a stihl carbide chain from friend and breaking it down to drive link I needed.

Man I am impressed with carbide chain for dry dirt encrusted root ball stuffs.

74dl broke down to 72dl.

Showing how far regular chain got before begging to be sharpened.

Nice stump if I don't say so myself. I have a similar one to grind out this summer and carbide tipped chains are cats butt, but expensive and have to be sharpened with an (read expensive) diamond wheel.

That root ball stump after I cut the tree up and then pulled it out.

This is it upside down flipped over pulling it out.

Maybe I didnt post this here last year after tornado.

New evercrip planted same year to replace the big winesap we lost. Already have another variety of those so didnt do the same.

I had feared of dirt ingested while cutting that stump up. It was falling in chunks right at the 2 front inlets on af cover. I was stopping and wiping them away.
Looks like the old 80's air filter system did fine even with it mesh filter.

Oh a past owner had open the back of af cover straight to air filter too. I had thought about putting a prefilter screen over it inside cover. But hasn't been a issue to date.

Husky uses chit clear line in some of their ope. Your lucky to get 2 seasons out of them even with E-free mix.
The fuel line itself is that small trimmer size I cant stand. It's going to normal size of other 2 too.

Updating this with with echo oem lines and think I got it all back so dont have to buy their stupid fuel line kit with junk line.

Removed the catalytic crap inside muffler so she will breathe better too. No cost muffler mod.

Waiting on carb kit. One I dont have on hand.

Only the 2nd one of these ever to come across the bench.

555FX Forestry Clearing Saw

Husqvarna 555FX is a very powerful clearing saw developed for full time spacing tasks in tough conditions. The X-Torq® engine provide raw power, rapid acceleration

www.husqvarna.com

I noticed on first one that came in I prefer the trigger style over the thumb throttle these use.

 

[xyz123]

All done. No way I could run one of these all day. My hats off to the guys that have to.

Like running a 53cc strato chainsaw awkwardly.

Carb rebuilt and checked. Still same zooming happening.

Told owner I didnt think it was carb kit issue from get go. But carb diaphragms were getting iffy. Plus got to put in a tan over that blue oem one on check side.

After troubleshooting came back to the cable on engine side to carb. Dealer said he just replaces the whole cable as common issue he sees.
I was able to remove rubber boot and lube inside best I could put boot back on and work it some and got it working. So good to go and even tested out in some weeds.

OEM walbro kit and they punched pump side diaphragm wrong. Luckily dont matter on this one and will still work.

Also the OEM Walbro carb made in China. Told folks for years they had a plant there too.

I prefer the thumb. I ran one a couple of times when I was between jobs... when you get into a rhythm you find that the rambling throttle is a lot more instinctive to use. It's hard to describe but often you are holding it against your thumb, and moving the saw against it as you are cutting.

They are easy to run all day when you are young... even easier when you're also hungry. I don't miss doing it but I do miss being able to.

Owner picked up the 555FX and coming back to test these 3.

Just wanting a limbing saw. Something lighter then his 2101.

I got a feeling which one he will pick.
But not married to chainsaw as I sold many of those over the years.

If that's a 346XP, I bet he chooses that one...

Ok, I have to Ask, "Why the Dual Throttle Bodies?" or 1 TR and 1 Carb?

Wouldn't a bigger Carb offer a straighter opening? Does the secondary lead to the Transfer Ports or something strange like that?

That is how stratified motors operate for a chainsaw. It's due to the EPA. It's a port that injects air into the combustion chamber post ignition to help with unburnt fuel.

Those that know, collect all the old saws that are pre strato to get a true two stroke design. My newest saw is a Stihl 361, Stihls last true two stroke saw. I have like 6 of them to last me the rest of my life. They are simple and never fail...

Thanks, I was a Saw Tech, but yes before the EPA got involved.

Just trying to figure out "Where the Air Enters?" How would it Scavenge Fuel? Wouldn't a Tuned Pipe d a Better Job?

I guess, We have a BR600 Blower at work 4 MIX that runs mixed fuel, it is still running after 12 winters of Blowing Cars. Strange Days

I couldn't tell you what works better as far as scavenging goes, but I suspect the engineers found a way to make it work to meet EPA standards.

@D'oh the extra is air inlet. Be on top or even bottom too.

Cheap poulan cylinder left before like we were used to with carb and the later epa strato right with extra air inlet.

Yep ran all 3 and took the 45cc 346 OE first year saw 1999.

He said he wanted a lighter husky saw for limbing some downed trees he already has waiting.
He used to have a husky 550 mkll for such, but sold it during down times in covid years.

Ok, that makes sense that it goes right to the Transfer ports, Piston Timed, but lower, not sure how it would get timed, or what it would do that a normal bigger bored Carb wouldn't do.

I knew someday one would turn up to buy right and used. Echo 501 bought PHO.
Which didn’t matter as I have all of that on hand.
Psi felt good and popped on choke all I cared about.

If good I can test one stock now then muffler modded to see.

The metal handle with rubber coating feels so much better then the plastic handles the cheaper version echo use.

Wish their better one came with mag clutch covers over plastic.

Mixed about those captive bar nuts.

Like standard recoil better then spring assisted one like on 490.

Quick muffler mod for no cost.
