I have seen those branded as Husky and Stihl as well!

Dare say your spot on...the chain is a Oregon .325 1.3mm that comes with the saw. Think I will try the 20 LPX chain , as i have 21 LPX on many of my other saws and find it ok.

As you likely know, that may or may not work on that saw. The thinner bar may create a clearance issue with the regular .325 chain.

It works on the 346 series saws, but not with the 550 series ones. Regarding the 242 I am not sure, but I believe some have said not..

Some saw models may be borderline, so it depends on production tolerances and the specifics of the chain (model and how far back the cutters are filed).

This is not something i assumed would be a issue..as the 20 LPX shows as 1.3mm drive link width i didn't consider if there could be any clearance issues across the cutter/chain size . The Oregon chain on the new saw visually looks the same size as the other 21 LPX i have on the others saws apart from the 1.5mm D link width.
Will put the callipers on what i have and see if i can work out any problem. Oregon do list 20 LPX as ok for the 420 though ...worth a measure though !
Added: I think i am at X purposes with your concern ..is you concern with the adapted 1.5mm width bars and chain rather than the existing Dolmar bar and a sub over to 20 LPX from the Oregon semi chisel .325 1.3mm that is already on the saw ?

 

[ajschainsaws]

No you shouldn't have any issues with chain clearance on that saw if anything wouldn't the 20LPX be the same size as the dolmar chain supplied
The backing plate to the clutch slopes back from the sprocket so plenty of room for chain and chips

I wonder if the dolmar ones where much sweeter

That was my assumption Andrew.. with the chain ...2 tanks through it now and all is well

They were mega sticky !! Tasty though ......there was a art to getting them out of the wrapper and into the mouth

20LPX is perfectly OK for the saw, but is meant to be used on regular .050 bars, not on NK/Pixel ones.

Many Europeans aren't aware that regular .325 and 3/8" bars and chain exist in .050, mainly because the saw brands don't want them to know.
The reason likely is very simple - they want to simplify the logistic situation, and at the same time avoid that people mix .325NK or 3/8"Picco/lo-pro components with regular ones.

Have added info on the post above before i saw this reply ....Think we are on the same wave length with the 20 LPX

I see where your coming from Again the husqvarna bar was helpful when you needed one quickly
I used too run dolmar bars K095 mounts . 325 and 3/8 in 050 , but now in recent years they are just too expensive and now anything destined for the U.S. market is very hard too get in the EU or impossible

Which bar would you say was a good combination with the 20LPX in K095 mounts

Thought it was about time for some feed back .
The PS 420 (uk 421) is well run in and i have tried it out in stages of tune.
1: out of the box
2: Guts of the cat got shot of
3: the cat section removed and the louvers opened in the outer cover.
Out of the box the saw was not so bad....bit slow to spool ,but then it was brand spanking.
I ran it like that for a few hrs and it got a little stronger.
Part Cat Gut...A slight decrease in spool time and a more willing power delivery.
Now finally....Full cat delete and more muffler outflow.
Spooling is nice and Zippy, with revs that feel "Unhindered " without the saw having a harsh and uncomfortable to work with sound.
The saw has been retuned each step and seems to be settling at 13200 free before bouncing or the limiter and will hold 9000-10200 mostly in the cut depending on how big the wood and if i dog the saw. I personally find it nimble for the general work iv put it to and its never felt a chore to use .
Now 2 Niggles !
The main top case needs the carb off to remove it and the throttle linkage rubs on a fuel line from the primer bulb when you trigger up....only needed to be a tad longer to miss altogether !
Fuel consumption is good doing field line work or liming ...1 tank = about the time i want between coffee ..45 mins-1hr ish .
Iv settled on the 15 in 1.3mm .325 combination and all the above has been on the Oregon semi chisel chain that came with the saw.
I am sure going to Orogen 20 LPX will see a even more pleasing result in cutting performance. Nothing has broke or come loose and the saw runs Sweet after the mods and bedding in.
Do I Like It ???
Yup I Do....Would i recommend it to a buddy to try ......Oh Yes !

Have you tested compression psi yet I was wondering as I haven't got the small adapter

No Andrew..I thought one of my testers went down to the smaller plugs but 14mm is the smallest i can do. Think 165psi was found on a" new " 421 by the chap doing the Porting Thread.

 

[merc_man]

Dam makes me wanna get my little 420 out and give it a try.

Considering where you are, just change to the 21LPX in .058, and bars will be available everywhere. There is no gain in using .050 over .058 with regular .325 or 3/8", as the upper part of the cutters are exactly the same. The drive tang (the lower part of the drivers) just is narrowed down for .050.

The alternative mainly is to buy bars from the US - unless you find a source that goes against the stream....

 

[ajschainsaws]

Thanks for that I always thought the cutter was narrower as well as the drive link but as you say the 21LPX is more readily available

Also the shipping for a ps-420sc from the UK to your village in Norway is only 33 euro

If I wanted one of those saws, I would have had it already.

It belongs to a category that I see no need for.

Has less than 3 tanks

Just under 150 psi
