So is that conditioner stuff kind of viscous like oil?

[RI Chevy]

YES!!!

I've never run both side by side so I can't really comment too much. I did not use the 026 this past year. This year I'll compare the 421 vs 026
Pro vs 5100s. I'm curious to see what I like the best

As far as running the saw goes I would prefer the 5100S but when it comes to working on the saw it's the 026 for me..

Late to the party i know, but, how is this straight gas experience going? My head started hurting when you said you were doing this to a 421! of all saws! The horror!

Couldn’t you do this to a Poulan or something! Aye carumba

Unfortunately I have seen quite a few leak around the boot, generally they have been caught before ruining the top ends, I really like the design of the saws otherwise, and nothing is perfect, I still consider them a terrific saw. Just something to keep an eye on.

I, too, would prefer to see a clamp on the intake side. There is plenty of room for an o-ring or jubilee clip.
I always felt the 026/260 was a bit of an under performer stock. But I have only ran one. They are nice and light tho. The 421/4300 aren't the lightest of the bunch, but you do get otherwise tank-like build for that weight. It isn't wasted. It's big where it needs to be. I like the 242/42. Ported ones run very well. Same with the 444/44. All in all, there is certainly a place in the market for a quality, torquey 43cc saw like the Dolmar.
And, if you are willing to add finger ports to it, they freakin rip.

The first saw in this vid is an Echo 360 with the cat removed and the baffle removed. So it is nearly straight through exhaust. They pull strong for their displacement. The saw after the 4300 is a ported 241. It also pulls rather well. So it gives you an idea how the 4300 is running after I've ported it here. This is in an 80 year old oak limb that is as hard as any wood I have ever cut in my half century of causing trouble on this planet.

Another vid showing that 241 kicking ass in 'normal wood'

Husky 444 ported to within an inch of it's life, 225psi, running a 16 inch bar with standard size 3/8 chain on it. This saw won the WA GTG that year. It is running rich in the vid, too. It will easily go to 16K all day long. I spent a week building it.

42 special. First part of the vid is how it came to me, then ported afterwards. Mark is fumbling a bit, but you get the idea:

What chains you run on all those.

 

[00wyk]

What chains you run on all those.

In the first vid they are all out of the box. Lemme grab the info from the vid:

All have new factory out of the box chain. 241 has standard kerf 325 Oregon semi chisel 62dl on a 16 inch Sugihara bar. The 360 and 4300 are using Oregon LoPro, and in fact have the exact same bar and chain set ups from the same manufacturers(15 inch Tsumura bars, 53dl Oregon VXL chain). The 044 has Oregon EXL chain on a 24 inch 84dl Stihl bar. The 288XP is wearing a set of 102dl Oregon DPX semi chisel chains on a 32 inch Tsumura L&T bar.

The 241 would be right with the 4300 if it had LoPro chain on it. It has a lot mroe carb and the manifold is massaged to allow mix in to the stratos. If you look at me after I run it, I stop for a second and look at it. I am surprised it didn't cut faster than the 4300. That 4300 really woke up with the mods I did to improve the scavenging. On the other chains, I am mostly tailoring them to the saw. The 241 typically runs much lower rakers than what you see int he first vid. The second vid with the 241 it is cutting a larch and then a spanish/sweet chestnut with lower rakers, so you see it dragging a lto mroe wood out of the cut.
The 288 and 044 are rich for break in - that is their first cuts since I put them together. Same with the 4300, too.
Here is it's third cut set to bounce off the rev limiter:

Thanks, just curious.

Thanks, just curious.

One of the reasons I ran all NIB chain was I knew that wood would cause people to ask questions. One of the first comments folks like to make in a vid is 'sharpen your chain' - ask any Australian. That oak is hard as a rock. But it allowed me to run all the saws in it. Any softer and I think the 044 and 288 would have just zipped through or required a much larger piece(both are ported) - which makes sense. But the difference between that 360 and the 43cc saws gives you an idea of how strong those 43's run. That 360 is very strong for 36cc's. I mean, I am dogging it in to a hard piece of oak there and it just chugs along. The muffler outside cover has been relieved so much that the tiny chromed cover is the same size as the hole. It's hard to tell, but it is also dual ported.

Ive heard it before, most my testing is in hardwood, it makes it easier to see the changes in times.
Whats funny is the only threads ive really seen any Aussie's do on chains are Bob's and that primarily focused on milling although there are plenty of things to learn. Id like to see more on what they do, from what I've seen id run big saws with 404 semichisel lol.

 

[00wyk]

Exactly. Same here. I have to cut dirty oak often. No way do I have time to sit around sharpening chain all day so it can cut 15% faster in super clean softwoods. I learned my cutting in California, Oregon, and Washington. Square chisel in fir is the way to go. In oak on a farm in Ireland, it's a good way to waste time. What's crazy here is it is hard to find 3/8 semi chisel. I have to bring it in from the UK or Germany much of the time. I suspect it is for the same reasons it's pushed there - you sell more chain because it has to be sharpened more often.

As a example , many sizes.
This may be a option for you as its semi chisel ...easy to get from ebay in UK and i assume the same for you. Its so cheep to try so maybe worth a loop as a trial.
I use there LP 3/8 on a small saw to cut up pallets ...bound to hit a nail or two. Iv 4 on the go and just rotate them as needed. The chain cuts well and Iv had no issues with build quality.

 

[00wyk]

Thanks, mang. I may give it a try next time I need a loop of 84. I am too skeered to try that on the 102dl 288xp bar.

Your welcome . Full chisel in large 3/8 is so under supplied as you say , micro or semi is my choice in all chains. It seems to cheep to be any good at just about 1/3 rd the cost of Oregon in the same size. Its not only a 1/3rd the quality.
Archer .325 1.3mm on a ps-420 is good to .

Before today I thought porting small saws was silly, something only a @Nutball would do.... After today you have me thinking I need a 42cc “ported to within an inch of it’s life”. Well done Sir.
