So, let me tell you a short story. Due to logistical issues at work the other day, I found myself without a saw. I had a smallish job to go do, but the boss had left with the truck before I got there viagra sans ordonnance france. All the working saws were on the truck… Quick thinking brought me to the Husqvarna 55 I had stashed at his house. It still needs the muffler brace fixed, so it had been parked in his garage, waiting on repairs. It’s kind been relegated to “back up saw” status since the purchase of the Jonsered CS 2253, poor little guy. I tossed it in the truck and went to work.

A view of the air box, minus the top cover. The filter seems to stay clean for a long time!

     It ran pretty good, one pull hot starts every time. I really like this old saw. It just plugs away and keeps on working, year after year. It kind of reminds me of a little tractor, not real fast, but ultra dependable (mostly, it has had a couple of issues). It revs up kind of slowly, but then again most everything does after running the CS 2253! I got to the job and gave it a good sharpening and fill up, and used it for most of two hours. One thing I can say is that the fuel usage on it is pretty amazing, I got in probably a good 45 min of cutting and the tank was about half full still.

     After finishing up that job I met the boss at another job and decided I was having fun with the little 55, so I topped it off and went a cutting. That’s when the saw started acting up. It would run at almost full throttle after letting go of the throttle. I messed around with it a bit and nothing seemed to change its attitude. I first thought something was stuck in the carb, since it had been sitting a while, like maybe some water or saw dust, but it wasn’t really acting like that. Deciding it was kind of dangerous to use a saw that wont idle down I parked it and went to thinking.

Minus the filter element side of the air filter. You can clearly see the two nuts and allen screw to remove.

     I decided it couldn’t be an air leak or any trash in the carburetor. Just by how it was running. The boss thought a throttle linkage was sticking, but I could clearly see that it wasn’t. This left me with some kind of carb issue. Thinking of that reminded me of it doing something similar years ago. Taking it to my saw mechanic he fixed it in about 5 minutes and said how this was a common issue with lots of old Husqvarnas. The screw holding the butterfly works loose over time and the butterfly can’t operate correctly. I could only be so lucky that the fix would be so easy. Hopefully I didn’t loose the screw out the exhaust side of the engine…

Tear down!

     One thing I have come to appreciate on this saw is how easy it is to work on. I also had the chance to work on the Jonsered CS 2253 a tiny bit, and it is absolutly no fun to work on! The Husqvarna 55 is layed out like an old pickup, whereas the Jonsered CS 2253 is like a new French car! There’s no room to poke around under the hood of the CS 2253, it’s full of wires, hoses, shrouds, guards, and magic.

Minus the throttle and choke linkages.

     On the top cover of the 55 there are a total of three screws to loosen to get access to the guts of this guy. Remove the one screw on the air filter and the back half of that pops off. One allen screw on the bottom of the inside of the filter and the two nuts holding the carb to the engine and the whole assembly is ready to be removed. I must point out that the two studs holding the carb to the saw was one of my mods. They came from the factory held together with wood screws… They had a propensity to waller out the threads (plastic manifold) and cause an air leak, killing the saw. (Because they hold the carburator to the saw.) Ask me how I know! I carved out the engine side of the manifold and epoxied two bolts in there, creating studs! A much better design, if I do say so myself!

Minus the carb, sort of. I didn’t need to remove the fuel lines for this operation, so it’s still attached by those.

     Pulling off the carb I instantly noticed the inside butterfly had some wear marks around the screw, like it had been bouncing around. Sure enough the screw was a few turns out. I unscrewed it a few turns more, dumped some Loctite all over the screw, and tightened it back up. I didn’t take it all the way out and do it right, because the mechanic had hit the screw with a center punch to lock it in, way back when. If I had taken it all the way out I ran the risk of stripping it out, and ruining the carburetor. I’m hoping the Loctite got onto enough threads to hold, but if it didn’t, it only takes about 10 minutes to take the saw apart, re-tighten, and reassemble everything.

A view of the errant screw, butterfly, and my masterful Loctite application. Notice the shiny bits where it rubbed on the intake gasket when it had loose wood screws holding it together!

     Going in reverse, I stuck the carb on the studs. I attached the choke and throttle linkages. I added the front half of the air filter and started the allen screw. Then I added the two nuts and washers to the studs and tightened all three down. Time for the back half of the air filter and then the top cover. Of course the grommet that holds the throttle linkage was upside down, so I had to tear it all the way back down and turn over the grommet, but it wasn’t a big deal.

     Starting the saw up revealed a nicely running saw. Throttle response was back to where it was supposed to be. I did have to re tune the carb, so perhaps the butterfly had been a bit loose for a while. I ran it for a bit to make sure to wash off all the excess Loctite before it dried up in places it shouldn’t be, and now it’s all good.

Husqvarna 55 carb fix

A similar shot. The butterfly is the golden round part. It has grooves that align with grooves in the carb body. If it becomes misaligned it can not close all the way, not allowing the saw to idle down.


     I’m glad this was an easy fix! I almost never get off easy, so I’ll take it! Time will tell if the Loctite works, or if I’ll just have to retighten the screw every once in a while. Like I said, it only takes about 10 minutes to tear it down, fix it, and put it back together. I really appreciate how easy this saw is to work on, especially after working on the CS 2253 a bit. They should have kept this saw in production and tweaked the issues out, at least in my opinion.

  1. “Uh ha.” That’s what I used to say to my dad when he explained how he fixed a TV. Very interesting but I didn’t have a clue what he had done or how he did it!

    1. LOL. Good thing I remembered the mechanic doing something like this a few years back, or I would have been fumbling around still probably. I was just nosy enough to stand over his shoulder and watch what he was doing too! Good thing I’m writing things down now too…

  2. Cass if you think the Husqvarna is slow you should have tried my old Homelight

    1. Ha, no thanks! I used an old Homelite or McCulloch, can’t remember which, with the thumb oiler. That thing would wear out your arm trying to pump the bar oil faster than it would cut wood! Now, if you think the Husqvarna 55 is fast for a 50cc saw, you should give my Jonsered CS 2253 a go! That little red sucker will peel your eyes back!

    1. It’s a ’98 according to the sticker, if memory serves… so that’s… yep, 18 years old! It’s mighty fine too once the couple of hiccups are ironed out.

  3. I made a joke once that dealing with the sort of problem you’ve written about here is like solving a murder. You start with the chalked outline of a body, and then have to use your reason and logic to work your way back to the criminal who did the deed. It was a great illustration of exactly that logical process at work.

    You’ve missed your vocation as a detective Cass.

    1. Hi, David! Thanks for the comment! I did try out for the state police once, they didn’t want me. 🙁 It’s all good though, as I can now turn my deductive analysis thought processes towards fixing chainsaws! I do love a good mystery, and believe it or not tools can give you some from time to time. With any luck, I have found solutions to problems others might come across! 🙂
