please help identify this carb

[n10sivern]

i have 2 of these lying around and i believe they are off a honda atc110 but i'm not positive. can somebody please identify the carb and what model it was used on and the years that it was used (so i can get a rebuild kit if i use the carb). if it is off a 110, then i would like to use it on an atc90 that i have. is there any problems or info that i need in order to use it on a 90 (if it is a 110 carb) or it is just bolt up and adjust.

Go on Keihin web site and cross the #"s

Looks like an atc70 carb.

could be a 90 or 110 carb too

i couldn't find any info on keihin's site. i google searched a hundred different ways and found 2 posts on other forums in relation to an atc110 and on atvheaven the part number CK-943-79 comes up as

"This quality kit contains all the parts required to rebuild your 79-83 ATC110 Carb. Includes "O"Rings, Idle screw, main jet, slow jet, needle & seat, circlip and tension springs. Made in Japan by Keyster.

Note: Suits carb model PB20A."

so, i'm guessing it is a 110 carb. would these have been stock or aftermarket replacements?
