I know about the 350 and only ran and seen a 450 at a stock saw racing competition.
What is the big differences in the 450 compared to the 350? Type build etc?
-
All I really know is that the 450 is the "strato" replacement for the 350, and that the specs are a bit up on weight and a bit down on max power output.
-
Hard to feel any weight difference.
450 is smoother.
350 is stronger.
-
Then there were two different engines used in the 350 - the original ones had a 49.4cc engine, while the later (US only?) EPA ones used the 51.7cc 353 jug, but with a dished piston to take the compression and power a bit down.
-
I just picked up a later 52cc model 350. Does this saw come with a cat muffler on it?
-
Mine had a regular muffler
-
350 is 3.1 hp. 450 is 3.2 hp. We have 450's at work now( local line man I am ) and the 450s feel stronger and cut faster then 350's. stock for stock anyways.

As far as I know, it never did.
-
My 2003 production 45mm/52cc 350 didn't have a cat muffler.

None of the plastic cased saws ever came with the cat muffler due to the effect all of that extra heat would have on the case. Heck, they melted enough of them with the loose muffler deal on the 2nd generation 350/2150. :)

Now that makes perfect since.

Is a 351 the same saw as a 353, but with the 44mm open port cylinder used on the early 350's? I've never seen a 351 in person or in a Husky catalog. A friend just told me he got one in a load of saws.
-
That's the way the OEM's look to me. 44mm open port

That's correct. 351 had the same P&C as the early 350. 351 to 353, (or Jonny 2149 to 2152), mostly mirrored the changes that apply to the early and late 350/2150. (with the exception of the metal cased saws getting a flat top piston vs the dished piston in the plastic case saws)
There's actually several changes between early and late saws on this chassis. Different, (course vs fine) thread hardware. Different starter pulleys and springs. Different air filter holders on the metal cased saws. Nothing major, but stuff to watch for when mixing parts on project saws. The one to keep an eye on is the cylinder bolts though. At some point they went from a course thread to a fine thread. If you mistakenly get them mixed up you'll bugger up the threads in the case!

Simple to answer, YES!
The 351 didn't last long, before it was replaced by the 353.

Thanks for the info gentlemen. Very helpful as always.
-
Thanks for the info. So would I be able to put a 353 flat piston in this 350 for more power? I got this saw cheap and want to play around with it a little.
-
I put a flat top in my 350, think it was off a 55

Yes

There's a Meteor piston for the 353 that you can use.

If it was off a 55, it must have been one of the rather rare 45 mm/51 cc closed port ones....

My bad, but believe it or not I have one of the rare closed port 55's
-
The meteor looks like a good piston, have to order one later this week. Looking over it more it has the plastic intake clamp so a metal 372 clamp will be needed too. Anyone know if there is a thinner base gasket for it? I only see one part #on the ipl.

I have several saws with Meteor pistons. The pistons look nice and the saws run well.
