I tried to get my dad's ole 1980 CB750K running after he had it sitting in his garage for the last year or so. I had bought it from him since he planned on either scrapping it or putting it out in the back pasture.  Anyway... I got a battery charged for it and put new fuel in it since the tank had been drained after the last time he ran it. It didn't seem like it was gettin fuel so i decided to loosten the bleeder screws on the bottom of the carbs. It took a bit, but fuel did slowly start to drip from the nipple. After the indication that there was fuel going into the carbs I decided to crank it over. It took a minute or so and all I got was a little bit of a pop when I quit turning it over.  I tried immediately again and smelled a strong gas odor. I quit turning it over and got off the bike just to see that the carbs were just leaking onto the block and the floor.  I turned the gas off and it quit obviously, but Why would it be doing that? I haven't had any issues like this with my smaller hondas, or even my sleds. What would ncause this?
