A cheap ms170... what could go wrong!

[BigChopper]

Tomorrow I pick up this little saw for £25, its got a new bar and 0.43 chain. Apparently its got running issues, it won't rev so something else to tinker with on the bench.

Hopefully it's all complete and there isn't any scoring on the piston, least it's got a spark so one less thing to look out for.

Got to be worth £25 right?

I have a 170, run a 14 inch bar and chain. After the warranty was off I removed the exhaust screen.
Works well, nice little saw, compliments my 261 stihl.

Absolutely! Good luck with diagnosis and repair. And I might add, hopefully not too many chinese aftermarket parts on the saw (like the MS180 I bought on ebay). The saw is in Europe (well, kind of), so it probably doesn't have a spark arrester screen.

Parts alone are worth that on ebay. Good luck. Nice light saw for limbing and small stuff.

Ms170, only saw i have.

Have a bunch of chains, bars. Always have spare new spark plug.

Chain tensioning can be upgraded to one on the side.

If fixing, handle is not fun to take on and off.

Saw gets the job done for me every time. Is it the most fun saw to work with ? I don't know, it is the only petrol saw i ever had.

Bike handle wrap comes handy if installed, as ms170 comes with thinner handle than bigger saws.

When i look at Huskies and Echo saws in the shop, Stihl ms170 in comparison looks very well built. Plastics look much much better to me imho.

Thanks for the hope.
I picked it up today, its a bit dirty and unloved looking. The petrol tank has lots of unmixed 2stroke, perhaps it's been stood so long the petrol has evaporated.

I'll have a closer look in the morning,

Doesn't take much to stop up the little orifice in that saw. Be fortunate if it is not stopped up.
I would pull the muffler first thing and make sure the piston is in good shape.
If you need to replace the carb it is very simple. Take the little choke linkage out. Take the throttle linkage out. Pry the control lever up and move over to the choke lever side out of the way. Replace the carb and put it back together the way it came apart. 8MM deep socket.

BTW. There are several versions of that carb depending on when and where. If you do replace it make sure you get the right one or the holes won't line up.

After I did one handle, I started applying some silicone grease to the rubber. Made it a lot easier.

I actually couldn't easily line up the handle when was puting it back together.
