Hey guys I just bought this fourwheeler put a new battery and carb. And I start it set idle and I put in reverse and she goes easily. So I go to go forward and it doesn’t budge. It’s completely dumb founded me. Plz help!!
I’ve spent 4 days tearing it apart and trying to figure it out.

 

ER, manual or auto? If you put the auto into HI or Lo and rev up it goes. If you do the same on the manual, nothing happens until you shift it into 1st with the foot lever.
