You are correct sir. And now it's too late to edit. Black solinoid= bad, white solinoid = new and improved.I think you're mixing up the solenoid colors. Black solenoid/white filter bad. White solenoid/orange filter good. Specifically for the MS261, no coil/control module needed. Part# 1140 007 1802
Do you have the black solenoid? If so, get the white one and let us know if it helps. Black one is known to stay open (flood) when you turn the saw off.Sodbuster, I'm not a huge gear head but I have the same saw and my assumption is once you ran the thing dry from the old fuel, it becomes a bit tougher to get going again on a refill. Why this is, I do not know, but I've gotten used to it and try not to run the fuel dry for that reason. Everytime I do, it does what you described. Start up hard, then putter for a bit, give it throttle and it dies out or really bogs down. I basically let it idle for a bit and start feathering the throttle and its fine from there.
And correction to Tadmaz, I previously quoted it was black, when it is definitely white.Thanks Woody and Taz, I have the white solenoid. It sat for a year drained of fuel, after I shattered my wrist. Ran a couple of tanks of 90 octane, off road fuel and Stihl Platinum oil and some Sea-foam, and now it runs like a banshee, and starts great.
Thanks for doing the math, didn't realize it was such a trivial amount. I run everything on 40:1 and tune the saws accordingly.
As far as the OP's 261, it does sound like the computer needs to learn the saw again after it sat for several months.
