20190707_114434.jpg 20190707_114622.jpg Hello, Im new to working on chainsaws so bear with me. I have a stihl ms 192c that smokes a lot from the muffler. I checked the compression test and it's around 100 psi. Do you think I need to replace the piston rings and seals? Thanks for your inputs.

Which fuel/oil ratio are you using (50:1 or 25:1)? If you use for example 25:1 and your carb isn`t tuned right it can smoke. Also is your carburetor tuned right? Don`t do it by yourself if you don`t know what exactly (depending on the situation) to do. You muffler can also smoke if it is oily from bar oil when it gets hot.

I use the stihl orange 50 to 1 bottle mix for 1 gallon. Also I forgot to mention after using it for a little bit I turn it off and then it wont start .
