My neighbor was trying to cut down a small pine tree yesterday with his MS-250. It would hardly stay running, so he brought it over for me to look at. I get my neighbors power equipment when the don't run correctly, sort of goes with the territory of doing this sort of stuff for a living. I don't mind at all, it helps maintain good relationships, which doesn't seem to be the norm these days.
Anyhow, his MS-250 has very little time on it and just needed the chain sharpened and carburetor correctly adjusted. I also dumped his 2 year old fuel out of it and added some fresh mix.
The air cleaner was loose on the box, as the snaps were spread out slightly. No big deal there, I worked them in some and got it to snap in place, even though I thought the entire concept was "cheezy".
Got it running, and set the carb, and did a few test cuts with a sharp chain. It ran OK, but not impressive anyplace for power or cutting speed. Not sure what cc's they are, but runs like about 40cc or so, absolutely MAXXED out with an 18" bar/chain set-up. It would have been better suited to a 3/8 LP 14-16" bar.
Go to shut it off, and it continues to run. Turns out the metal spring deal had found it's way under the switch. I asked the owner and he said it hasn't been shutting off, so he's been choking it to kill out the engine.
Fixed that problem, then put the air cleaner cover back on and it's doing the same thing again...WTF??
Take the cover back off, which is another adventure all in itself. Couldn't they come up with something a little better there?
Turns out if you left the start switch in the upper or "run" position, (which is another thread all in itself about how complicated a simple operation should be) and tried to install the cover, it pushed the spring clip stop under the switch.
Anyhow, got it all back together and working correctly for him.
Not really wanting to start a Stihl bashing thread or anything of the sort, but that saw just wasn't showing me much for the price tag. I don't know how many cc's they are, but it wouldn't hold a candle to an Echo CS-510, and probably no faster anyplace than a CS-370 or 400.
What ever happened to a choke lever that works like a choke lever?
I'm glad I never got all wrapped up in the "lengendary" Stihl saw thing, because I'd be as unhappy with an MS-250 as I was with the POS orange Poulan's Husqvarna dumped on the market a few years ago.....Cliff
