high idle

Just moved to ne kansas from high desert ca. Was here in summer my 2003 blaster ran fine. I dont believe elevation an issue. However quad last ran then too. Getting alot of snow and wanted to go blast thru the powder snow :). Bike kick over on 3rd kick. New fuel. Bike when choked about same as not..only it wants to start idling faster and faster. Engine feels hot. Any trouble shooting help? I want to have some fun but i dont want it to run too lean and such and blow a top end. I am not sure my premix ratio off hand but its like a pint in 5 gal fuel ams oil...whatever ratio that is without looking :).
