Ok I'm working on my dads 2003 rmk 600. Sled is 100% stock and has been since new. I have a bog/backfire issue right off of idle. I've pulled the carbs and cleaned them with carb cleaner and compressed air. I've reset the fuel screws to 2.5 turns out at this time but before I took them one turn out and adjusted out 1/2 turn at a time with no real difference in the issue. I've also put in new plugs. Where it is set now, if I put it at half choke, it will not bog on the lower end but then run like crap at 4000+ rpms. With the choke of it bogs and backfires off of the bottom end but if you feather it or Half choke it to get it going then turn the choke off, it runs awesome on the top end.
Where do I start with this? I'm at about 4000 feet and ride from 5000-8000 feet. Stock carb setting should prevail right? Doesn't sound like a tps issue or temp sensor issue because it runs good on the top end? Needing some input, thanks
