My brother has a new one and it is the same way. I don't know what the deal is with that.
Jeff, what year is your Ranger? I haven't noticed any smell from my 2011 500. It run almost exclusively Shell premium in it.Hey fellas,
Wondering if anyone else notices this with the carbed 400's: The exhaust is so acrid it brings tears to your eyes! We had a decent snowfall up here and, like any red-blooded male with two kids and a recovery strap would do, decided to wake-board behind the machine on a kid's toboggan today (wife driving, God bless 'er). Yes it was fun and no I don't care what you think about safety. I found the stink behind the Ranger to be worse than any old 2-stroke sled. Question is: are we simply spoiled by catalytic converters and "unscented" exhaust or, do I have a carb setting that needs attention? I run premium gas, with stabilizer/Seafoam on occasion. Thoughts?
Those are two very different machines.......a carb'd 400 and an EFI 500. EFI will automatically adjust the fuel mixture.Jeff, what year is your Ranger? I haven't noticed any smell from my 2011 500. It run almost exclusively Shell premium in it.
yah true. i guess thats where ya keep an eye on your oil though and see how rich of gas it smells. im sure if it was that rich he'd have fouled plugs all the time though dont ya think?Wagz a machine that's running way too rich will fuel wash the rings out. Yes it's better to run rich than lean but too rich will cause the same amount of damage.
Rod, I run premium (and Jeff probably does too) because in Ontario, Shell's premium is ethanol free. Even though my small engines don't req' it, I run it across the board, since the gas can may sit around before it's refilled.Cooler air = leaner. So I wouldnt suggest jetting down. They dont smell pretty to begin with. But some of your smell could be from the Premium. More additives in it and burns better with a higher compression motor. Wich our rangers are not. Not trying to start a octane debate...just saying where some of the smell may be comming from.
:encouragement:Kris, I hear where your comming from. I used to run the Temiskaming Abitibi trail system a couple times a year through the winter. Fuel could be iffy at times depending on where i fueled up.
True, almost all 87 octane fuel on Ontario is cut with undrinkable corn liquor, so my small engines run premium with Sta-Bil.Rod, I run premium (and Jeff probably does too) because in Ontario, Shell's premium is ethanol free.

The Mikunis use a jet needle, needle jet & main jet to calibrate the air/fuel mixture thru the throttle range. Not as simple as a quick carb adjustment. I know in the VM series of carbs there are quite a few variations/sizes of these components. Not sure which series of carb is used in the Ranger nor the availabilty of tuning parts.I haven't dug into the Mikuni manual, but getting a leaner mixture involves more than turning a set-screw, I imagine? Pardon the ignorance...all my other carbs (Stihl, Yamaha) have external settings.
Other than an idle adjustment screw, what "external" adjustments do the carbs have?If it's just a tad outta wack I don't see why you couldn't play with the air/fuel mixture screw to fine tune it to where you like it.
