I've bought ready made 2 stroke gas once in a pinch.
We've got a chain of gas stations called Casey's that have ethanol free 87 at every pump. The Gulf near my house and another independent shop on my regular route also have ethanol free 87. I just mix 1 gallon at a time of 2 stroke fuel, from one of my jerrycans of ethanol free I keep around for all of my other 4 stroke small engines.
I'm not as wild about the MS211 anymore. I finally replaced the spark plug. Maybe the 3rd time in the 4 years we've owned it that I've had the spark plug wire off of the spark plug.
The terminal came out of the boot. It's the most chintzy plug wire terminal, spring that wraps around the spark plug and tail of the spring has a little 90° literally pokes through the insulation on the side of the plug wire. No mechanical fastener at all keeping the terminal spring on the wire. The only thing holding it in place is the terminal boot. The terminal boot has little wings on it with grip as though you are supposed to pull on them, pretty much guaranteed to pull the boot from the terminal if you do that.
I'm guessing Stihl sells a lot of $$$ ignition coils this way, since the plug wire is potted in the coil and too short to put a proper terminal on.
I managed to slice the boot length wise with a razor knife and put it back together like the wire and terminal were a hot dog going into boot hot dog bun. I smeared some RTV in it and cinched it closed with some tiny zip ties. It works, but I dread the next time I have to remove the plug wire from the plug.
Also smoked the clutch on the old Husqvarna this weekend. Only 33 years old, they just don't make things to last anymore.
Bunch of Chinesium options on the jungle site for replacements, but I got a NOS clutch and drum from eBay.
