My 07 600 ho rmk is runnin real rich. hardly idles and blows clouds of oil on snow.Plus the dealer put too much premix in tank but thats gone now. Just wondering if anyone knew how to adjust the oil so she runs a bit leaner. Probably should bring it in to the dealer but if it wasnt hard to do i wouldnt mind doin it. Other than the oil issue, shes one awesome sled. pulls hard and likes to go fast. any help would be appreciated.
