Snowmobile Repair: snowmobile has no power, oil mixture, driving a car

Question
Just ANOTHER QUESTION  would it do that if my gas and oil mixture is 50:1 instead of 20:1  I was told that it is suppose to be 20:1  

Answer
Well if your sled calls for 20:1 I would run that in it.  If you run it too lean your gonna lock up the motor.  It's like driving a car with no oil in it.  The only way that would cause your problem is if the motor was starting to sieze then when it cooled down it was alright.
