49.7cc air cooled 2 stroke engine. I took a couple videos to better show what’s going on. A couple years this exact same thing happened and we took the carb off, cleaned it out, the jets were clogged, and it ran fine for a long while. Recently the same issue happened and we saw the jets in the carb were clogged again, cleared them and it ran for only one day. We did this again and it once again only lasted a day. We tried to troubleshoot it and we replaced fuel filters and even popped the tank off and completely cleaned that given there was some sediment in the bottom. The spark plug was also recently replaced. We put fresh fuel in and it worked for one day again but then back to what you see in the video. Every time it works for one day, it runs very strong for that short period of time. I don’t know too much about diagnosing small engines, so any advice on what to trouble shoot next would be appreciated.

We have a 2023 stihl fs 56 RC 27.2cc 2 stroke which randomly a couple days ago started idling low and the head would take longer to engage and the body would then rattle while it runs. We adjusted the idler screw, took it apart to make sure nothing seemed cracked or disconnected, and the driveshaft and everything there seemed fine, and we checker the head to make sure it was fully attached, took off the carb and cleaned it, cleaned everything, lubed, and reassembled, and are just struggling to pinpoint the exact issue. I’ve included two videos which show the problem better than I’ve described it, I may have butchered that. Any help would be greatly appreciated. My best guess now is the clutch assembly and may order one of those to replace. It’s 2ish years old and we clean this thing religiously and only use it every few weeks residentially, so although I may be wrong, doubt it’s anything majorly wrong.
