hay stanley, are your valve seated properly? you could also have a few bent or cracked valves that are not sealing, which will cause no compression. also your piston rings could also not be sealing. try pouring a little bit of oil down each cylinder to see if that will build up some compression. My name is larry runyan and i'm a member, so if you still can't figure it out, just let me know and i'll help out as much as i can.
