I've found a few threads that sound similar to the problems I'm having, so I'm guessing I have a carb and/or fuel pump problem. (Rhino 660 not sure what year)
The rhino will run great for awhile and then start to sputter badly, backfire and then stall. I usually have to wait a couple of minutes before it will start again.
It seems to happen pretty consistently when I start to climb a hill or while climbing a hill, if I ease off on the throttle it sputters right away.
It has also happened on long flat ground runs...as soon as I come off the throttle it starts coughing and backfiring.
I'm a recovering City Boy, so I'm kinda naive with this type of stuff...any help would be appreciated.
