Trouble Shooting Rhino 660 Basics
The most common problem with the Rhino*660 and 450 as well is fuel being siphoned out of system back to tank while sitting...this makes for very hard starts...
The second most common problem is idling, warm-up, and all around run-ability due to a wide variety of air/fuel/spark problems...
The third most common problem is backfiring and/or popping on decel and/or down-hilling...
The common denominator is always fuel...or lack of it...it should be the first thing you check...
When it comes to power when you floor it...the biggest gain there is on a rhino 660 is at the intake with proper jetting...a good high flow intake with correct fuel curve...even with stock exhaust...cures a lot if ills...
It is a myth/bunk-story that you need an airbox to make the stock carb work right...the opposite is true...a good high-flow-intake with correct jetting will make the carb function infinitely better all around in addition to a lot more power to the wheels with vastly improved throttle response...especially at higher elevations...lack of air flow at the intake is a serious draw-back of the 660...especially in years 05-07...in 2004 they did not have the rubber snorkel from air box lid to engine cover...bigger main jet...they had more power...less noise...but still need a bigger pilot jet...we recommend to anyone needing a snorkeled intake to make a custom one with large I.D. pipe...get an adapter to clamp on a kn filter...
If you don't need a snorkel...odds are you don't need an airbox...however...you can simply remove the rubber snorkel from your airbox lid...seal off the hole in your engine cover to block off noise/dust...re-jet the carb...that what we call running 04-style...
If you don't need and airbox...and are not a foamer (foamers refuse to use fabric filters under any circumstances)...our custom 3" intakes feature custom made for us...heavy-duty-off-road-fabric...rock solid mounting...fit like a glove...filters have huge surface area to continue to have high-flow-capacity even when very dirty...make great power even with a stock exhaust...less noise in cab than stock intake on years 05-07...
Whenever it is not starting/idling/running right follow the basics...
1. Verify fuel-delivery to the carb...this is infinitely easier with transparent fuel lines...every fuel-delivery/fuel-line-kit we sell has transparent-fuel-lines...
2. Verify fuel level inside float bowl at idle/revved in neutral...and again at time of malfunction...every fuel-delivery/fuel-line-kit we sell lets you do this...
3. Check connection/condition of spark plug/wire/cap....
4. Test with airbox lid OFF...see how it runs...that does not mean go dirt riding with a loose filter...it is just a quick test...floor it from a stop...
5. Tune carb...we sell the jets you need...and provide tech support to our air/fuel customers...
With one of our premium fuel delivery kit installed and a carb tune...95% of the time the problem is resolved...the fuel delivery kit makes isolating/identifying/recovery infinitely easier any time you have any starting or run-ability problems...including the ability to manually-pump-fuel thru the whole system to overcome problems like vapor-locking, stuck floats, or fuel siphoned back to tank while sitting...
