True, it is touchy. Too high and it leaks, too low and it starves. I don't think it's any more risky than shutting your fuel cock off or forgetting to turn it on though. IMO these engines aren't as sensitive to damage running lean as motors with tight clearance.
One thing I do suggest. Carefully measure the positions before adjusting so you can always get things back in case mixture wasn't your problem.
