Hi all, my first post to this forum. I have a Stihl Ms361. It always starts 3rd pull, when it starts it runs at full throttle for 5-7 seconds and then quickly dies. I've replaced the carb and the coil, also have removed the fuel filter. When replacing the carb, I checked to make sure I could blow through the fuel hose, so no blockages. I'm wondering if this could be a compression problem, but when pulling it over its not an easy pull unless I use the compression release. Any suggestions would be appreciated.
