What is the differences between the 254 and 154 husky, and how good of saws are they? What is an average price i can expect to pay for either in decent condition?
would one in good used shape be worth a hundred bucks
There are two differences in 154/254 that I'm aware of may be more. 154 had a smaller combustion chamber than 254 and I think tighter squish. After SN: 3XXXXXXX 254 crank was changed. Don't remember what but I have Service bulletin on it. Having said that get it doesn't matter which 154 or 254 both great saws. I've got 5-6 myself in various stages. $100 if it has good comp. buy it!

I got here too late for the OP but for the record, principle differences between 154 and 254 were as follows.
(Note: Different markets may have received different combinations of specs/features at different times.)
In Australia, these were the main differences, as I remember.
Early 154s had Mahle "chrome" cylinders and alloy ported but full-skirted pistons.
Later 154s also had Mahle "chrome" cylinders but with ported lightweight "skirtless" pistons.
254s had KarlSchidt "nikasil" cylinders and ported "skirtless" piston.
Early 154s had a standard Walbro carburetor, similar to the 444 carb.
Because the porting and combustion characteristics allowed some operators to tune their saws to run unloaded, at 14,000 rpm or more - e.g. Finnish pulpwood cutters who routinely tuned their saws for maximum chain velocity for faster limbing - later 154s had a Walbro carburetor with a fixed minimum-flow hi-speed jet.
254s had a slightly different Walbro carb, also with a fixed minimum-flow hi-speed jet
254s have a slightly wider starter housing than 154 with more air intake area and the pulley further away from the flywheel. The pulley also has a longer steel sleeve which better engages the flywheel pawls.
254s have stiffer AV elements than 154.
Early 154 had push rod operated chain brake (like the 61/162).
Later 154 and all 254 had inertia brake.
Early 154 used the the same ignition module as 50 (and Partner 500/5000). When it was found that it was possible for the engine to start in the wrong direction if you pulled the cord too slowly, a unique Electrolux module incorporating an Iida Denki control circuit - which both triggered the spark at very slow pulling speed and had a diode to prevent starting in reverse - was introduced.
Of interest, the 154 was the first Husqvarna saw without a steel insert in the centre of the flywheel and the alignment key cast into the flywheel, the first pro saw to use EMABs ignition module, and the first pro saw to use a fuel tank from a farm saw, the 50. Though a more sophisticated air vent was subsequently added to all production 154 and 50 fuel tanks.
BTW "XP" is just a sticker. There is no difference between a 254SE and a 254XP.
Cool thanks. I had read somewhere that 154 had some differences from the rest of that family but that is good to hear that the externals fit anyhow.I’m assuming you mean other than the whole 262/261/257 family?
55/51 clutch will fit, clutch cover too, functionally but not “cleanly”, as the top rear corner needs to be cut and ends up not really matching.
I never tried to put a 50/51 clutch cover on a 154, probably because the early 50 inertia brake with a weight in the handle would spontaneously trigger at 154 kind of RPMs. Later "knee-link" brakes should be ok.I’m assuming you mean other than the whole 262/261/257 family?

To clarify: will the later 254/257/262 not work on the 154 flywheel?I never tried to put a 50/51 clutch cover on a 154, probably because the early 50 inertia brake with a weight in the handle would spontaneously trigger at 154 kind of RPMs. Later "knee-link" brakes should be ok.
I remember the 50 cover being a few millimetres wider too but if it fits after surgery...
Partner 400/500/5000 clutch/drum/rim will also fit.
154 starter cover is unique. Early 254 starter will work perfectly but is slightly wider and the longer steel ferrule in the pulley should engage better with the flywheel pawls.
