Not sure who you are gettin your parts from, put member here Nate fordf150 got me the parts I needed. My local Stihl dealer said most of the parts were NLA. It was mainly because there distributer never sold or stocked any of the parts. His/Nate's distributer had most of the parts in stock. Glad to see it is coming together for you. Do you have an IPL and SM for the 660?

I have about 15 years experience with running Stihl saws in cold Northern B.C. conditions,working at a big Stihl dealership. Stihl saws always ran very well in extremely hot climates and wouldn't vapour lock like the other brands because the Stihl carb box is so well isolated from any engine heat. However this design became a curse when running them is sub-zero cold,-40 was not an uncommon temp. these saws had to run in,but the carbs received absolutely no engine heat and consequently the saws would freeze up and quit while the Husky's ran fine. In 1984/1984 Stihl had no fixes or "Winter" kits and our shop really struggled to keep them running. Finally Stihl started making winter kits you could purchase and install on different models and they worked well. Then eventually you could buy a new Stihl with the Arctic kit installed and heated handlebars too which is the way to go.Maybe they will discontinue the Arctic versions but I would still think that the "Winter Kits" (Without heated handle parts) will still be available,I guess if you want heated bars you might have to just purchase the parts?
In any event I can tell you their winter kits kept them running fine,and are essential in extreme cold conditions.

In 1980 my first 038AV came with a winter air filter rubber flanged cover and rewind housing plate.
1984 my 034 came with a rubber flanged rear cover too along with the plate.
But my 064 in '86 was the best at the time running in -30 to -40 with its HD winter kit.
The 044 in '88 didn't have a flanged cover available,  had to use duct tape.
Winter of 1991-'92 I field tested a 044 for the factory that had heat coming from the muffler to the carb via a copper tube.
1992 my new 066 Mag Arctic came with a electronic heated carb. Carb heat was thermostatically controlled to be 77 F year round. I never logged with that saw though.

I remember around 1990 for the 930 Jonsered you could buy a heated carb kit from Jonsered,consisting of a generator that installed under the flywheel and a heated pad that mounted in front or the carb,but was too expensive and most "Jonny-reds" weren't known to ice up the carbs,they generally ran ok in cold weather without any mods, of course they did have the typical little window in the top cover you could open to suck some warm air from the cylinder.
I've never seen the 044 muffler heat you mentioned,but I once saw an ingenious heated handlebar a guy installed on an old 051. He attached a small copper tube to the muffler which went in one end of his full wrap handlebar and blew right thru and came out the other end,it actually worked very well and he had a small 1/4 turn brass valve in the line so he could adjust how much heat went thru the handlebar,I was impressed! So simple yet it worked well,and didn't cost a couple hundred dollars,just about $10 of parts..I think a guy could build something simple like that at home for one of his own modern saws on that principle...

The Jonsereds like the 930 had no problem getting heat from the cylinder to the carb through the intake manifold bolts.

That 044 with the heat tube to the carb was just a factory experimental. Partner chainsaws had a muffler heating system tied into the handles. Was adjustable but many complained not adjustable enough.
Jonsered had the first electronic heated handles around 1975.

I had the partner heated both handle ones on 5000 490. Muffler exhaust through tubes.

Page 6 has some pics where I had to redneck the tubes for hit on the 5000 plus with tygon to the oem tubes. http://chainsawrepair.createaforum.com/partner/partner-5000-plus/msg4722/#msg4722

Kevin, those are cool setups. You can see they had to put a heat vent hole in the top covers like on a 550/562. The tubes were blocking the normal path of the cylinder cooling air flow.

I know most of those guys from the Loggers sports circuit in the 80's and early 90's,Ron Hartil was a nice guy but I could never beat him,came second to him in one event and was quite proud. I was just a mechanic from a big saw shop who like to build racing 2-strokes but only went in local events,I wasn't part of the circuit. I remember when Ed Braun lopped a few toes off doing the standing block chop in running shoes.
I'm pretty old and dumb with computers so I'm not sure how to chat on this site,I'll try.
My email is trappermike@telus.net
I actually prefer to chat on skype,much easier than endless typing which I'm slow at...

Thanks Mike, Skype doesn't work for me as I got too many distractions in my house,Lol. Kids, wife and dogs.

I started logging as a faller here in northern Manitoba in 1974 at 16. My first skidder operator partner Dale Quinn moved on to logging in Prince George/ Grande Prairie around 1979.
Around 1983 he showed up at a local Saskatchewan competition with a b-bomb hotsaw he bought off Ron Hartill. He couldn't get it to run in the competition and a couple of bikers in the crowd were yelling insults at him. Dale's ex stripper girlfriend yelled to the bikers to "F" off and took a swing at one of them.
In the under hand chop Dale put his axe into his shin.
Never heard from Dale again for 35 years until a year ago when I friended him on Facebook.  It turned out he did pretty good in the B.C. logging sports despite his rough beginnings.
Apparently he got Ron's b-bomb running pretty good and even won the PNE Canadian 100cc title once.
I competed only a few times in the Canlog competitions due to living here in Manitoba so far from B.C. But I did come close tying Ron Hartill in the 100cc and under class in Sayward in 1988. Had a good visit with him at his home at Cowichan Bay. Learned lots from him.
