Problems after cleaning spark arrester

480 Views 5 Replies 3 Participants Last post by  WTsportsman
2013 sportsman 850 EFI. Decided to clean the spark arrester and when I cranked it up and gave throttle like the manual says it spit out a little smoke and then started revving high rpm and spitting erratically. I screwed the arrester back in and it is still doing it and shows the engine light now. It was running fine before I did this. What did doing this cause?
