I need a little advice about an FA-30 I have. The engine has not been run in nearly two years. I turned it over (without a prop), and the exhaust valve stuck in the open position. I could feel the piston touch the valve, but I don't think I did any damage. I took off the valve cover, put a few drops of 3 in 1 oil around the stem, and worked it free. It seems OK now and has good compression.

Now my question: Am I seriously tempting fate if I try to run the engine as it is, or do I need to take off the cylinder and remove the valves and fully clean the valve stems and guides etc.?

Thanks for any thoughts you fellows with a little experience can share in this matter!
