Questions: I have a 1951 M38 (I think) and the only marking I can find on the carb is Carter YS. Will this kit fit? I know similar to other question on here but I couldn't find any other numbers.
Question By: Chris on Dec 4 2018 2:28 PM
Yes, if you are a YS side draft and a M38 then it should be correct for you.

Questions: my carb has a metal triangular tag stamped "636SA" and under says "CO" will this kit work? will part number 923806 work as a direct replacement including linkages on an Lhead 134 m38? they look different
Question By: jason on Mar 13 2017 6:49 PM
It should say WO on top of the bowl on it. Check again. Yes on 923806 for a replacement for the Carter WO.

Questions: Hey there, We have an old military style 1952 Jeep with a one-barrel carb (4 cyl). The markings on the carb are YS 0-818 CARTER. What rebuild kit should we use as I cannot find any solid information on this.

If you have a M38 with a side draft YS then this should be the correct kit for you.

Questions: I have a Carter YS carb, there is no tag. On the opposite side of the carb is stamped 0-818, will item #648065 work?
Question By: Todd on Mar 28 2012 12:00 AM
As long as it is a M38 with the YS it should be the correct kit.
