Default YS110 engine help needed

This engine was in storage for a while (~ 3 years) and today I noticed that it has no compression. In checking the rocker arms I see that the intake valve is stuck open. I put some penetrant oil on it but I suspect I may have to pull the head and work the valve from inside. I may need to do this anyway as the intake push rod does not move so in removing the head I will be able to remove the intake push rod cover and free the intake "cam follower". Since I have never disassembled a YS engines, does anyone have any guides on how to do it?
Thanks in advance,
Matt
