I was wondering if anyone has used a TRX90 carb on and ATC110 or 125M? Some of the parts are interchangable and I was wondering if this would be a good carb to buy for a 110?

I asked a reputable Honda guy and he says this will work but the jets will need to be changed.

Make sure the stud spacing is ok for the manifold , the 110 might be wider .

Good advice. My neighbor has a TRX90. I will measure it before purchasing.

I have run a 125M carb on my 110. Jetting is the only difference. I'm not sure about the 90 though.

I ended up buying a TRX90 bowl gasket which stopped the leaking carb issues with my 110. I had tried multiple bowl gaskets from ebay and other aftermarket sources but all of those leaked gas.
The honda TRX90 bowl gasket worked perfectly.
The honda part number for the TRX90 bowl gasket is 16163-GBG-960.
I believe this will work for all ATC110, first gen ATC125M and first gen TRX125. Not sure about the ATC90 as I have never worked on one of those.
