ms250 carb question

[Nathan Graff]

Is it worth buying a real walbro for this saw, or is a clone good enough? I know there are some saws that I've read to not bother with the clones. Is there a good place to buy a clone?

Short story on the saw. I had a friend get it. She said the saw was hard starting, but it idled well and ran well for 10 minutes that were counted by a timer.

I got it yesterday. The saw wouldn't start no way, no how. Today, I fooled around with it by taking the carb out, and cleaning the outside, and popping off the limiter cap. Retuned the saw a bit. Saw will now start, but will not idle. If one lets off the throttle, the saw just dies. Adjusting the low speed jet does nothing. Saw runs on fast idle, and full throttle, but smokes like crazy.

Took the muffler off. Piston is not scored that I could see. Can see the machining marks the whole way across. Compression is 135 psi. Fuel is slobbering out the muffler. Spark arrestor isn't dirty that I could see. Just a very small bit of carbon build up in one area. If it hasn't ever been cleaned, the saw has hardly been used in it's life. The spark arrestor actually looks fairly new. It doesn't have a burned look to it like it's been torched off.

unfortunately, no. i ordered one for dad's ms170, and it was just about $65 cad. That's over just about $50 us.

Stihl dealer prices in the Ohio/Ky. region....

I wish. But it's not. It's a lot more here. Over $56 for the carb, and $8 for delivery.

go to a Stihl dealer.

That is at the stihl dealer. Parts in Canada cost about double what they do in the US for just about everything. New stuff in Canada is about half again more from US prices in most cases.

There are a few on Ebay Canada for about $40 (inc shipping), which is roughly $30 USD. Not sure which province you might be in, but I'd guess another 5 for taxes.

Would start with a full carb kit first, maybe new jets if you can get them.

Without looking I am guessing you have a tillotson, if you are looking to switch to a walbro? Usually a new kit and they are good.

No, it's a zama.

To help with your search:

There looks to be a difference in the carb throttle levers if you have the primer bulb or not on your MS-250.

LsEngineers.co.uk gives the following Walbro options:
WT-215
WT-286B
WT-1007 BR

Tillotson gives:
HU-131A (without primer)
HU-132A


Looks like 1123 120 0603 is the WT-286

1123 120 0603 is a Zama C1QS76b
The carbs for the
"primer" bulb versions have an extra nipple...

If Tillotson makes a carb for the 025/ms250, it must be them trying to get in the aftermarket market....

It is a quirk I discovered a few years ago, the Tillotson carbs are typically used on the euro saws. When you look at the EU vs NA specs, the EU are a few cc higher.
