So I recently got my hands on a nice shape 10mm 044. I got carried away while there and ended up with a MS 461 and MS 200 rear handle too but that's a story for another day. I've been looking for an 044 for a while and this one will do... for now, haha.

I would like to convert it from the old style flat mesh filter to the new HD2 but don't know exactly which parts I need. I've downloaded the 044 parts manual and it's kind of confusing because the original filter base and new version don't look like they would seat the same.
If anyone can explain it to me that would be great. And don't be afraid to dumb it down.
As well, do I need to go all oem or is there an aftermarket solution that is good?

Thanks?

Your carb probably doesn't have the intellicarb attachment to connect to the air filter base. You can use epoxy to fill it with on the base if not needed though.

Aftermarket air filter base, air filter, air filter attachment stud, and filter cover would be all you need.

Here’s what I purchase for my early 044. I had a few spare new filters for my 066 so I don’t have a link for those but I know I got them off HLSupply. I also opened up the stock muffler hole and took some of its guts out. It made a world of difference and of course required some retuning.


I didn’t use the top cover, only the filter base and its cover.

That's great guys, thanks so much for the help. It's exactly what I was looking for.
I would prefer OEM but really, who cares, this saw will be a user, not a museum piece.
These aftermarket covers are ok to use. They dull fast in the sun, but fit well enough.

Fitment was a lot better than expected and for $23 I have no complaints. I don’t think I had to do anything other than put them on to get them to fit. I don’t remember much, or any, cussing 🤷‍♂️

You do have to double check dimensions, I got the Farmertech covers for my 066 and they did not fit at all, they ended up being for the newer 066/660s. Cheap? Yes, can't complain about that, but just parts now taking up space on my bench.

044–440 were all the same size. I believe your early 066 would be the same size as the 064. I don’t think there is any aftermarket support for the 064

Great visual and parts breakdown for a conversion.

I might also need to sort out what all it entails. As I am learning more and more about the differences in 044's ( other than the 10/12mm )

I see variations in Carb suppliers, Tank Vents, airbox styles etc. I will say that my particular saw has the flat mesh filter style and a Zama C3G S5E carb, I am pretty sure that I am clueless if I would need to swap carbs to make the HD2 filter and parts all fit.

Answer will be appreciated.

Thanks huskihl,

I appreciate your knowledge and advice as well as any tips from others who have helped the OP and of course myself in learning our 044 saws.
I've had mine for a few years but have only recently encountered a relatively new issue. I had to seek help in what direction I should take to remedy the possible cause. When I posed the symptoms, one member suggested that I likely had a wet cylinder issue. He and I discussed how this happens, how to diagnose and stop it. The potential cause he suggested was faulty operation of the metering lever/needle valve and then he explained how he would go about fixing it if it was diagnosed that fuel was leaking by the needle as the saw sat for any length of time.

At this analysis, it was the beginning of my actually getting to know a lot more about 044's and my particular 044 specifically. He questioned me which carb my saw had. Walbro or Zama. I had to go out to my trailer so I could disassemble the saw and get the carb off. Zama C3M s5E.
Then, I decided it was best if I had a rebuild kit on hand before opening up the carb. So, the next thing I learned was JUST WHAT part numbers and kits would get me an OEM part. I do not want cheap Chinese junk. So, from my model, the Zama part number was supposed to be RB-36 or 615-839, but those are hard to find that are not knock offs. I dug deeper and found some threads online that showed the OEM Stihl rebuild kit number is 0000 007 1080. I managed to locate one at my local dealer but at their location 40 minutes away. Cost, $30.86.
Found another source for the same part @ $28 for 2 kits. Once they arrive, I will disassemble the carb and see what conditions I find in the needle valve area, do a thorough cleaning and rebuilding. Then retest the carb pop off pressure and needle sealing with compression tester before installing back on the saw. I will clean the whole saw and inspect and test all the fuel lines, filter etc and replace any bad parts. One issue I caused was breaking off the brittle tubing that attaches to the fuel tank vent, so I will make up a new one.

This brings me to the general areas of concern that I got to learning on my saw, vs parts breakdowns and what I hear other guys' saws have.
Over time, Stihl used Zama and Walbro carbs for the 044. They also had different style tank vents, and different style air filter parts. Of course there was the 10mm vs 12mm saws, and I am sure other iterations. Heated, Autochoke carbs?

That is about it for now, but I encourage anyone who has one 044 or more than one that are outfitted differently, to post what your saws include, and any details such as part numbers, kits to modify air boxes, maintain the oilers, electronics, starters, clutches etc.
My saw is so new to me that I haven't had enough time to learn the actual parts and how they come apart, go together and act as a unit yet.

Thanks and hope this helps others.

Best bet will be to get a hold of some 044 IPLs and then compare part numbers and part types (filter shape, vent types...etc) and narrow down your saw being closest to one of the IPLs and then you will have all of the part numbers your heart will desire!!

This IPL is a link for a 2004 saw: Stihl 044 IPL - 2004.pdf

If your parts differ from this IPL then I recommend connecting with @ray benson , he seems to have access to a plethora of IPLs and should be able to help you out.

Yup, Thanks hacskaroly. I was one step ahead of you on getting with Ray Benson. I have gotten IPL's and Service manuals for my 193, 201T, 261 and 026, 660 and 044 from Ray. Pretty sure that leaves me with hard copies for my 051, 075 and Husq 394XP

I will look at the 2004 IPL link you posted as well. I am looking forward to hopefully getting a rain free day today through Saturday so I can get back to mowing my 3 yards, then back home to make progress on cleaning up my 044 to ready it for an overall visual inspection,checking the timing situation, clean the saw top to bottom, clean the air filter and check the fuel filter, pull starter etc.

Hacskaroly, I really do appreciate your advice and thank you for posting. If others can benefit from any info you, myself or other post to help out, that is my aim.

Being able to get back to seeing if my saws that have sat would fire up and run well, sure felt good on Monday. Thumbs up for getting my 2-026's, 261 and 193T all running well. Then there are my other "new to me" ones like the 044, CS 3000, 201T, 660. All but the 660 need a little something. Some diagnostic, some simple maintenance items like filters, plugs, good gas and a cleanups.

First the 044, which are basically having a hard to pull when starting issue. As noted, possibly needle/ metering lever problem, but still to be determined. Possibly a similar scenario on the Echo, but before it began acting like the 044, it was also stalling when turning it sideways. Gotta check for air leaks, carb issues etc.

Wish me luck, Carb rebuilds are easy enough, but should I find any air leaks in bearing seals etc, we all know what that means.

Some times finding leaks or resolving issues does take a bit of luck we can all use! One thing with the potential air leak when turning the saw on its side, with the saw running, spray some non-flammable break cleaner on the suspect oil seal, if the saw shuts down (no harm, the non-flammable break cleaner just stops the combustion cycle) then you know for sure the oil seal needs to be replaced. You can do the same around carb intakes/boots to see if there are air leaks there too.

It sounds like you are having a good time working on your saws, that is great to hear, it is a good/fun skill/hobby to have!

Yessir, thanks for the reminder of the non flammable brake cleaner. The saw that stalls out is the Echo. I put a new primer bulb and fuel lines/filter on it, and had it cutting a few scrubby limbs on some 4-6 inch trees last Summer when it decided to begin acting up once I cut the limbs off and turned it sideways to cut the trunks. Decided I didn't need to fight it, and grabbed my 193T to do the rest of the job.

With plenty of currently running saws and not so much the same for String Trimmers, the Echo will likely come in the line somewhere in the midst of all my saws, string trimmers, mowers and blower fixes.
