MOPED ARMY

I just a 1979 Honda express2 na50, the issue is that I have a crank and no start condition. I checked for gas, spark and compression and it has all three. Could it be possible that the timing could out? The next thing I’ll check for is to make sure that the woodruff key in the magneto side broke off or non existent it’s a crazy thought but enough to check for. Any thoughts out there? Any guidance would be helpful, I got the with the condition already existing. Thanks in advance and ride safe.
