Ok I've got a problem. I own 2010 Yamaha grizz 450 and it won't start. Getting gas,good spark and new plug. I've ran a tank of gas out from bottom of the carb. It did get ran w no anti-freeze. No temp lights came on(if there r any). It's not blown cuz I have compression and it started once since only idled touched the gas and it died and hasn't started since. Plz plz help I just feel it's sumthing small. Thank you for ur input!!
