I am a long time user of Stihl chain saws and have had trouble starting them in the past. Than I found out the proper way to do it and now I can start any of my six Stihl saws when I want. So I guess there is a trick. OKAY, First set the function switch to the choke setting, the last one on the switch. Do NOT touch or operate the throttle. Pull the cord four or five times and the saw should burp once. When that happens move the function switch to the next position which is the part choke position. If it doesn't burp, than move the function switch to the part choke position anyway. Do NOT touch or operate the throttle. Pull the cord . It might take several pulls but the saw well start. After the saw is running, than you can operate the throttle. The secret is to not mess with the throttle because if you do, than you have just flooded it. You need to have good gas and a healthy ignition system but this has worked for me every time. I love my Stihl chain saws.

I've got the same saw and I use it a lot. I really have no troubles with starting it but...
1-Don't miss that first burp, even if it's barely audible. Then flip it down to half choke immediately or yes, you will flood it.
2-Yes, it's got some stout compression. Consider slowly rolling the engine up to the first bit of compression, then return the rope all the way before giving it a sharp pull while the saw handle is well braced in your crotch. I've been surprised more than once if I get lazy and make that first pull a drop start, especially when the saw is cold. It'll sometimes give an unpleasant jerk. A hot saw will be much more forgiving of a drop start.
Once you learn what not to do, it's a pretty friendly little saw.

Yes, it's got some stout compression Thats exactly what I am talking about . Even trying to relieve the compression doesn't t seem to work anymore . I have had this saw Ms250 for years and its never been this bad .
Well the good news is that it's gaining compression as the years go on 
.
If my Husqvarna 288 has been sitting for a while the first few pulls are harder. It does help me a bit to pull it through a few times slowly before the first real pull.
You could pull the head and add another, or a thicker head gasket to lower compression a bit?

A trick i do on a drop start with my ms250 is to hold the top handle by the top bend down so the saw tilts a bit away from your body/legs. This way if the saw hangs up on a high compression pull and the saw blade jerks down it will go away from your body. I've gotten lax a time or 2 when i didn't tilt the saw and it touched my leg on a compression grab.
Luckily it didn't fire but it was a healthy reminder.
The light weight, and grabby compression of the MS250 saw adds to it's squirrelly nature.
My bigger 029 super doesn't need the same hold position. Straight drop works fine on that one.

FYI at past 20 minutes in the video above she tells you it was a carb problem.
