My name is Doug and I am new to the ATV world. I bought my girlfriends kids a 50cc Hansim ATV and it wont idle. The idle adjustment screw and the fuel mixture screw seems to do nothing. Carbs aren't very expensive for these on eBay so I'm just going to purchase a new one. What i need to know, is the carb on this ATV a 16mm or 19mm and does it matter? Thanks in advance. And I'm sure i will be using this forum a lot.

 

Welcome. If you didn't already, ask your question in the Chinese quad part of the forums.

 

Ok thank you
