My 2005 Arctic Cat Firecat 700 EFI sat for almost two years whil I was away for work. I Sta-Bilized the gas before I put it away. Today I fionally got the time to fire it up and give it a once over. It did fire, but ran really rough and wouldn't idle. I added a couple gallons of fresh 87 octane I had, but it still won;t idle, and it bogs down when I first crack the throttle. Then I added about 6 gallons of fresh 93 octane, but its about the same. I also changed the plugs. Does anyone have any ideas what's going on? Thanks!
