This thing.
It’s a Husqvarna (with a Q) 236 chainsaw, from Huskvarna (with a K) in Sweden. The town changed its spelling, the company didn’t. Actually, it’s probably made in China but it’s spiritually Swedish.
It’s powered, as is the nature of machines like this, by an example of the !!!error: Indecipherable SUB-paragraph formatting!!! . The starting procedure is:
Push primer six times
Pull choke
Pull starter cord three times or until the engine tries to start, whichever comes first
Push in choke, pull cord two or three times and engine starts.
When it was new, all of the above went just fine. After a year of ownership but very little use you can pull the cord until you’re blue in the face before it starts and even then it proceeds very reluctantly indeed.
So I investigated, suspecting that stale fuel that had sat there until it dried out wouldn’t do much for the carburettor. I eventually extracted and opened the carb to find nothing amiss. Put everything back together and eventually succeeded in starting the engine but still had to nurse it into keeping going.
So we’ll need to adjust some adjustable bits. Here they are, down the holes marked T, L and H. T is tickover speed, L is low speed jet and H is therefore high speed jet.
Except we can’t, or not easily anyway. Emissions get in the way. To prevent the owner fiddling and increasing usability at the expense of the environment the jets are adjusted by exotic splined screws. Husqvarna don’t readily sell the tool needed. Fortunately though the carb is made in
China and you get the tool posted from there for about €3. Might have to do that then.

Use a drill to spool up the motor

I
’ve had
a Stihl for a few years and ran into the same issue this year
. I tried
to clean the carb
which looked fine
. In the end, I bought a new carb on eBay and that fixed it.

I’ve had an Echo trimmer for nearly 20 years. It’s been getting harder and harder to start over the last few years. It has these plastic limiters on the jet screws which keep you from turning them more than 1/2 a turn. I popped both of them off so I could turn them a bit further than intended. Now the trimmer runs like it did when it was new and it no longer stumbles as it revs from idle to full throttle.
You might be able to replace the needles with something you can adjust. Find your local small engines guy and see what he can offer.

My dad gave up on one of those last year. I think someone grabbed it to try to fix though. He bought a new one which he is apparently not strong enough to start so he can only use it when I’m visiting.

While I generally love gas powered anything, this is my baby right here. Sweet, sweet electricity means it runs every time, no dicking around.

We’ve got a Husqvarna 456 Rancher from 1993...still works fine. However, when saws get like yours they've had some crook fuel. I'd wager the carbie jets are blocked or damaged. And of course you've cleaned the air filter!

I have an echo that I cut the catalytic converter out of, removed the stopper tabs on the carb adjustments and richened up from the emissions limited super lean position. Runs great, haven’t had any trouble starting it and idles like a champ (nothing like trying to restart a chainsaw at the top of a 33' extension ladder)

Filter’s fine. It runs better when warm - as in after ten minutes or so - so I don’t think the j ets are blocked as such. I'm sticking to my emissions theory.

That’s fine if you’re within extension lead distance of a power supply! We had an electric saw but gave up on it.

Yeah, I have a very small yard so it works great for me. But if you have a lot more property then I can see the need for a gas saw.
