TRX 400 2004 won't run after valve clearances?

A friend has a TRX 400ex, he checked the valve clearances (as far as I know) tightened them a little as they were loose.

Since the above the bike hasn't started, I've had a quick look at the manual and set clearances to 0.1 and 0.12 and it still won't run, it seems such an easy straight forward job I can't understand what has gone wrong? Am I missing something? It's the first time I have ever touched an ATV, I have worked on dirt bikes a lot. I am reading about a decompressor adjustment?
