My son's Tao Tao ATV was bought new as a 110cc quad last Christmas. I looked at the MFR's plate on the frame of it yesterday and it says the engine displacement is 149 cc.
Engine family on plate says 7vcox150aa1

I want to get a new carb for it but don't know what to get.

How can I tell what the engine displacement is? I haven't seen any info plate on the engine at all.

 

first all chinese 150cc engine use the gy-6 honda clone, this engine uses a CVT transmission, also uses force air as cooling so it has cooling fan and shrouds around the engine cylinder. also uses a cv carburetor.

the 110cc should have a black cast iron cylinder with the cc's cast into the left side. it should read 107cm

you can e-mail me a picture and i'll tell you what engine you have. luvmysxs@yahoo.com

 

Thanks! I went out and took a some pix and sent them to you.
It may be that the factory stuck on whatever plate they had on hand.
