Hey guys, a guy I work with brought me a MS250 that is bogging pretty bad.

I don't have an IPL for a 250, heck I've never even seen a 250 in person. I ordered a OEM Stihl carburetor from Ebay, PN 1123-120-0620 that was supposed to be for a 250. There is a nipple on the top left facing toward the clutch side that isn't on the carb I took off. What is the correct PN for a MS250 carb?

I will post in the beg for manuals thread to get an IPL and the service manual later.

Thanks,
Jared

So I have a little more information after receiving the IPL and SM.

The carb that was on the saw originally was a Zama C1Q-S76, Stihl pn 1123 120 0603.

The carb that I bought off Ebay appears to be a Zama C1Q-S75, Stihl pn 1123 120 0602 (even though the Stihl box has 1123 120 0620 stamped on it). This carb is for the easy start version, hence the additional nipple on the top left.

The IPL shows that some 250s came with a Walbro WT-215, Stihl pn 1123 120 0605. The orientation of the carb adjustment screws are entirely different between the WT-215 and the C1Q-S76 and even require a different boot.

Is the WT-215 a direct replacement with the corresponding boot?

This is the first clamshell saw I've worked on and I am ready to drop kick it across the shop at this point...

IIRC, the 215 will fit all of them, but there is a different grommet. It’s got some odd setup where the H screw is adjusted through the handle, or something like that.

Tremendous amount of variation is carbs on the 025/250. If you have a primer bulb variant, you’ll have to block some lines to use the 215.

Yeah, the carb that came on the saw had the L needle adjustment hole through the side of the top handle.

The 215 looks like both the H and L adjustment screws will be accessible to the left of the handle with the new grommett. No primer bulb on this saw so the 215 should work Doc.

Thanks!
