Hey everyone, i am a new member and am haveing problems getting an old sled running right. I have an 82 yamaha srv540 single carb that is only running on 1 cylinder. It has good spark, good compression and is getting fuel. but it wont fire on both cylinders. i have no idea what is wrong with it. i have checked several things and they all seem to be good. is there any posibility that it is not getting fuel to one cylinder with a single carb. i have already checked the intake to make sure that is open and it is. please help if you can. thanks.
