Just purchased a Rhino 450 with 62 hours. It runs fine but will not idle. Always backfires a few times and dies. I have replaced the fuel filter and fuel pump as well as check and blow all the lines. I adjusted the idle and checked the plug and it looks OK so did not repalce. Now before I start messing with the carb or spending bucks on a CDI it's time to back off and look for some help? I have read all the threads I can find. I certainly would appreciate any help!
i have a 660 but mine wouldnt idle after it sat for a while.......i pulled the carb out and took it apart and cleaned the jets in the carb especially the idle or main jet, and its fine now. when you get it apart take a torch tip cleaner and run the right size through there and it should fix it
