    I have gotten a bin of parts (Mainly Stihl) and in the box of parts was Walbro WG 931 carb inside. I went on Walbro's website and found out that the Wg stands for 100cc or bigger, but I can't find the carb online or what saw it goes to. I have a hunch that it belongs to a bigger stihl. Any idea what saw it belongs to?

    You sure it reads WG-931?

    I recently cam across this list from Walbro which lists the Walbro carbs used on Chainsaws and Brush cutters. There are not many WG carbs in the list and only one that is a WG-9. I'm sure the list isnt 100% but it's the only resource I have found to date. See attached.

    The Husqvarna 3120 used a WG carb but not the 931.

    An 075/76 with a WG carb would be highly modified.
    They are much larger than an 1111 carb and the carb studs are set wider.
    The WG is comparable to the tillotson HT that is used on the 084 and 088/ms880.

    An image of the model number area of the carburetor would help to clarify which carburetor you have. Some model are easily mis-read.

    BTW not all of the model are listed or shown on the Walbro site.
