My neighbor gave me his near mint condition MS250. His wife bought it for him new about 4 years ago. In all that time it's cut about half a cord of wood and trimmed up a few down limbs on his property.
He's had it over here half a dozen times for me to look at it, and back to the dealer once, who told him it needed a new carburetor.
Every time I've had it over hear, it's required a slight "tweak" to the carb, I dump out his old fuel, it runs flawlessly, and off he goes with it.
This last trip he says to keep the saw and he never wants to see it again. I drained the old gas from it, and it fired right up. Once again just a tad out of adjustment, but very close. I had some down trees from a recent storm so ran two full tanks thru the saw....flawless.
A month goes by, I get it out, starts right up, idles a little funny, dies out. Starts right back up, idles OK for a minute or two, dies out. I didn't have time that day to do anything with it, so I grabbed one of my 55's instead and completed the job.
Another couple weeks go by and yesterday I pull it out to see what's going on. It's down about 2" in the tank so I fill it up. Fires right up, and ran flawlessly thru the entire tank, never had to touch the carb or anything else.
Just looking for some ideas from anyone with experience with this model to find out what's going on? Vent issue? Fuel line? Dirt floating around in the carb? It doesn't act like it's got any air leaks anyplace, because when it does run, it runs right thru the entire tank and never grumbles once. The problems both of us were seeing, is that some days when first started up, it woln't stay running at idle and has required numerous very slight carburetor adjustments to get it back in tune......Cliff
