Most everyone here is saying it’s a fuel issue. A possible air leak likely as well. Check the rubber boot between the carb and cylinder. That boot generally has accordion like folds and is susceptible cracking. A crack is hard to see on a bottom fold unless you really look closely or remove the boot and inspect it. These cracks form when the saw gets pinched and the user levers the saw back and forth trying to free it.
Also my 1992 stihl 044 has never developed a fuel related carb issue. The carbs never been rebuilt and I keep gas stored I the tank always. Even in the off season. The only exception is when I run out gas and I just don’t refill it until the next use. I use non oxy gas available at a local station and Stilh 2 cycle oil. And this saw still runs like a beast. At times the set screws would vibrate and need an adjustment. After replacing the runner boot that holds them in place from being hardened over the years it’s been good. The same goes with my boat I purchased in 88. Same gas and Stihl oil. Gas has been sitting in the carbs for almost 40 years strait. I only use my boat about 5 times a year or less. It fires right up every time. The same goes with all of my small engines never having carb issues with local non oxy gas. I have 3 lawn tractors, 2 pressure washers, 3 generators, wood splitter, 4 wheeler, golf cart, 2 chainsaws and boat. I live in Mn so most of these things sit several months without being used.
To each his own, I’d never pay the $$ for pre mixed canned gas. They’re selling you the same thing you can pre mix yourself, much cheaper.
