Does this model have the same carbureator as the standard Green Rhino. I noticed the Special Edition I have has dual exhaust and the Green one had single. Was this standard or was this a mod? The reason I am asking is, when I am pulling a hill in LR 4X4 it starts missing, like it is starving for fuel. My son thinks it may be a sticking float. I may just buy a new Carb and want to make sure I get one that is right for the model as I just defined.
Thanks in advance for the help.

Hey there slow poke...somehow I answered this question and it logged me on as you. To further response, a dual exhaust in not stock, which for one can mean your to lean jetting wise if never done and dependent on altitude.. If your unsure of that one other mods could be on it like a K&N air filter which you should throw in the trash, if it has one, a CDI and who knows what else.

So you are saying that a K&N is not a value added item? I could not tell what you meant by CDI. Good or bad, I always thought they were value added although I don't know yet if mine has one. I need to check.

Well....The K&N debacle is like an oil brand war. Put it this way. Take out the K&N and assuming its clean hole it up to the light and look thru the media. You will see pin holes in the gauze. Use simple logic and tell yourself no fine sand,grit or anything gets thru it. Think about K&N's sale's pitch, " the dirtier it gets the better it works. What do you think that means? It flows better when dirty? no, it means the pinholes in the gauze media are now plugged up and its filtering better. Would you use a basic paper filter if I took a piece of .005 wire and poked hundred of holes in it cause it flowed "better" I doubt it. If you want the best filtration possible for your engine use a stock filter of get one of the many oiled foam ones.
The CDI (ignition) unit is a change or "upgrade" that can alter the rpm limiter points, alter timing or otherwise. If your Rhino does about 38 to 40 which is factory speed then you probably have the stock one. If its capable of better speeds its likely a aftermarket CDI unit. Its really hard to diagnose running issues without seeing and hearing an engine run. Altitude you ride at, modifications to ignition or motor or exhaust and the unknown others may have done can have ill effects if not done right. High rpm's like climbing hills or muddin need fuel. Clogged fuel filters, weak fuel pumps, plugged carb jets, wrong carb jets, worn plugs with the wrong gap all can have an effect.

Rhino's didn't come with dual exhausts just a single muffler.

That's likely a "dial a jet" set up which is an aftermarket add on that can be removed and returned to stock. Ive never had an experience with one but from what I read they are a mixed bag and may be part of your problem. No offence to the endless good stuff one can buy but for every beneficial part there are an equal number of not so hot parts that are more trouble than their worth. Even adding an exhaust without proper jetting will decrease HP and torque numbers. Working in the aftermarket motorcycle industry it was pretty sad to see just how bad this was at times with follow up tuning. Personally I cannot see a dual exhaust on a low performance 660 having much value but that's just my old school opinion.
Noise dont equal power. It closes open ohv areas and pisses people off.
