OK Honda maniacs, a friend of mine has a 2003 350 rancher and claims that the 4 wheeler runs great at a horizontal plain but as soon as he inverts it to climb a hill of any degree it stalls and will not start back until leveled back out.
I suspect it's a float problem with his carbarator but I am not a honda guy so give me some ideas before we tear into it blindly.

Thanks for any advise,
Mud

 

That's the first place I would look......the float setting and check to see if there is any trash in the float bowl itself.
