Before shot of how much smoke the hr214 throws off

So I'll be tearing down the hr214 later in april, but i wanted to record this to show how much smoke it throws off during start-up. I'll definitely be replacing the rings on the gvc120, but i'm not sure if i should order the valve stems too. Here is the vid...

First pull start with the choke on (you can tell when i turn it off and the engine speeds up) I asked a few guys on the net who have done this job before what they think about the valve stems...we'll see.
