Hey all! I ran up my snowmobile today other days it was running fine, But today the exhaust made a popping noise at 3000 rpms then when I press the throttle the rpms go down. Has old gas, 2 stroke, And the spark plugs are new but used them while trying to get old gas out. Little bit of more gas still in. Anything helps! Thanks!

Hey! Thanks for the replies, i’ll get right on that. It’s idling weird now. And still making that backfire noise from exhaust at 3 rpms and when choke is off it goes down to 1000 rpms then dies, even when i press the throttle under 3000 rpms it sounds like it’s turning off.
