Question:
Have there been any small or incremental engineering changes to the Husqvarna 450 over the year or is it identical to the first 450? I am asking about the 450, not the 450e.

Doug,
Just a thought, and I have done this on some of my Husqvarna models. Download all of the IPL's (Illustrated Parts Lists) for every model year of your chainsaw, and you can readily see the changes, and sometimes its part numbers, or sometimes a little different version of carburetor. Also Most Husqvarna chainsaws have different carburetors available for the same chainsaw.
In-addition, some of the IPL's on the last page will list the specific change from the previous model year.
Here is a link to the IPL's for Model 450's: /images/us/support/download-manuals/?query=450&types=I&brands=
I hope this helps! Also, In my opinion most of the chainsaw models, are being constantly tweaked from model year to year.
PS. I am Not a Husqvarna Representative or Authorized Repair, just an experimental chainsaw person.

solid advice indeed. I can share one engineering change that I created in my workshop.
after a recoil starter failure on my old 450. I welded a small length of 1/8" flat steel with a grade 8- 3/8" nut perfectly centered, then drilled 2 holes in the ends and bolted it to the flywheel.
now I start my 450 with a drill driver using the reverse gear and an old 9/16" deepwell socket.
no more ripcord starts for this old workhorse! just a trigger pull from an 18v drill.

no more ripcord starts for this saw. I should patent my design...

Robert,
I have thought about an electric start or battery start gas powered chainsaw, but a couple things come to mind and one is safety. Please be careful with a battery drill, remember that gas powered engine has a lot more torque and horsepower than the battery drill, and with no clutch to slip, if the engine were to fire late it could do some damage.
Second problem is maintaining the balance on the flywheel, so that you don't wear out the main crankshaft bearings pre-maturely with that extra piece of metal on the flywheel, and third is making sure that piece of metal doesn't come flying off the flywheel at 13,000 RPM's.
Anyhow, just my two cents!
PS. I usually find that I can tune-up the chainsaw to have it start in one or two pulls, and If it doesn't start then there is something wrong with it.

Thanks all. I was wondering if there were any factory tweaks to fix issues as they came up over the past decade- like the common chain oil leak. I did pick up a new one on Saturday and so far it is everything I need in a saw.

Doug,
Thanks for the update, and good luck with your new chainsaw.
Just remember to maintain it periodically, and always clean it, and sharpen the chain after use, and it will always be ready for the next use.
After you get use to cleaning it up right away after using it, you will find it always looks nice, works well as designed, and really only adds about 5 more minutes to your work time. Keep good fresh gas in it with the correct fuel oil mix, and if your not going to use the chainsaw for a while, empty the fuel from the tank, and then run the engine until it stops. Put it in case or cover it up to keep it clean, and put it away until you need it again.
Again, Good luck and I'm sure it will be a great chainsaw,
Karla
