« on: November 22, 2014, 12:44:18 pm »
Husqvarna 242xp 242 etc. OK folks with all the talk of this little guys lately. I want to learn more about them and their variants.

Open or closed cylinders bore etc.    pistons too

238 is smaller bore then 242  and 242 smaller bore then 246?  Do they all used the same crankcase or just 242 and 246?

School is in session. Teach  ;)

According to Husqvarna

242SE = 2.3KW/3.1Hp.
42 = 2,1Kw/2,9Hp.
242XP = 2,4KW/3,3Hp.
242XP Cat = 2,3KW
246XP = 2,3KW
246XP Cat = 2,3Kw

42 Special has same piston cylinder as 242xp



Info look right?

husqvarna 42 special  hmmmmm same as 42?

It is, as far as I know the "special" designation was just marketing in this case.

The open port models in that "family" are the 42 and the 246, all the others (133se, 234se, 238se, 242, 242xp) are closed port. I know nothing about the pistons. The 42 and 246 were supposed to be less costly (and less "aggressive") altenatives to the 242/242xp.

The most interesting model is of course the 242/242xp, as that one was in production for a long time, and vent trough more development during production - and publised specs have varied a bit. The forst xp ones (about 1991-1994) were pretty much the same saw as the 242, while more sunstandial "updates" took Place around 1994.

I am not by any means an expert on those saws, just have picked up some info here and there.

Except for your comment on the 42 Special P&C, that fits well with my overall impression, even though the Kw mumber for the 242xp sometimes is listed as 2.3kW. That differense may or may not have happened around 1994 - see my post above.

My understanding is that the crankcases are the same and that the main distinguishing feature is the P/C between the models.  There appears to be some difference over the years in which carbs were used.  Whether this also means differences in intake blocks, air filter necks, various linkages and parts, I could not say, though the various IPL could surely answer that question.

My understanding is that 234 and 238 were closed-port models, also.  Both P/C are NLA so far as I am aware.  Some long-time users of these models report that the behavior of the 238 in real world use hit a sweet spot and was preferred to the 242, even though the 242 developed a bit more power.

I did post (and received no info in response) over on AS inquiring as to production numbers.  It seems that 242 and 246 were fairly common, 42 and 42special (which I understood to have the same P/C as the 242, though not confirmed by #s) are nearly as common, and the rest are pretty darned rare here in the US and in the midwest, particularly.  Eastern Canada and Maine appeared to be places where these saws were popular in commercial use.

I'm not sure about the weight specs.  If I had a good scale and the patience to drain the cold bar oil, I could go out to the garage and figure it out.  I do know that side by side with a 346xp (NE), the size and weight difference is noticeable, both running the same b/c setup.  And for some reason, the metal chainbrake handle models within this family feel noticeably heavier than the plastic chainbrake versions, out of proportion to the actual difference in weight between the two clutch covers/brakes.

The thing that many of the specification-lovers miss in this is that these saws occupy a unique position in terms of handling.  It is tough to describe in words, but you can flick these saws back and forth, side to side, faster than the 346 or 026 or other similar models, and they feel so much more solid than the other 35-45cc homeowner saws, even though the weights are probably pretty darned close. Factor in throttle response compared to the homeowner saws of similar weight and size, and the fact that you're comparing apples and oranges is pretty clear. 

Power-wise, nobody will dispute that they are not the most powerful saws out there, or even within their displacement class.  I had a mildly ported white top 44 a while back and while it had a real edge over the 238 in the firewood pile, just as the 346 has, neither the 44 or even the 346 can make that claim when working in the woods.  So if your work involves cutting lots of little stuff - small tree thinning operations, felling and then limbing smaller-sized conifers, or in my case, cutting large stands of buckthorn trees that are usually 0-6" diameter into manageable pieces for groups of volunteers to drag away - the saws in this family have a handling advantage that makes up for being a bit low on power and torque compared to other saws that are usually considered to be in the same class.  If you are going to be operating in bigger wood, or wanting to run a 16-18" bar, then it is probably not the saw platform best suited to your needs.

The 246 was my favorite of the bunch. Made a living with them for 10 plus years. Prefered the 246 to 242 as it had better torque. My 2 ported 246's were equal to a stock 346. Probably the toughest saws I ever used. That limbing video I did years back was a 246.

My favorite new saw the 241 lacks the speed of the 242/246 but blows them away with torque.
