I figured it out by taking air cleaner off first and looking into carb when someone shut off the car for me. The carb was just literally dropping the a little bit of gas for about 15sec after car was turned off.
I hinted carb when I had pulled out a spark plug and smelled gas on them. Reason I pulled spark plug was because I had no start. I also noticed that If I kept cranking engine it would start in long run but hesitated when I accelerated.
I bought a fuel pressure regulator at autozone and walla! I also took time to tune carb while I was at it.
