Hot starting question

With the air cleaner on or removed it acts the same. If you don't touch the gas, it cranks over but won't fire, you would almost think it was flooded but when you look into the carb the butterflies are dry. I've also pulled the plugs to confirm and they are dry.If you give it a pump of gas but don't hold the throttle open the same thing, it won't fire. The fuel line and carb body are not hot enough that you can't hold your hand on them.The idle speed is set for 600 in drive so the throttle blades are not open very far, that's why I'm thinking it needs to draw more air.
