Oregon | You don't need a new saw, you just need to get that one sorted out.
Try a fresh mix with fresh (not farm tank) fuel.
If that doesn't work, try this from a saw forum:
"Yup, the MS 391 has a decompression valve....just like my 036 Pro. The thing that is unique about the MS391 is that its carburetor has two butterfly valves...one for the choke, and the other for the run. It also has two choke settings, which feed different amounts of fuel during choke. I have found that after sitting for a few weeks, two pulls on "cold" choke, then switching to "warm" choke, for two pulls usually results in a "burp". Then, if I'm lucky, it will catch and start to run if I give it full throttle. Once it runs for a few seconds, all is well, and I can cut for hours with no trouble. It is very touchy though, and if this routine doesn't work, it will flood, then I almost have to pull the plug and clear the cylinder before I can repeat the process. I have found other people who have had the same issue, but they say that once it gets 20 or 30 hours of run time, and breaks in good, it generally starts much better"
