Onan Backfire - Not A Good Thing

When not traveling I run my Onan 2800 for one hour under a 1500w load every other week. Always, when starting it takes a couple of tries for a few seconds for it to start, drawing up gas from the fuel tank I would assume. This past Friday I fired it up and after the second try the engine back fired. Pushed the start button again and it fired right up and ran smooth. Now, not being an expert, I would think that a back fire is not good for the engine. The temp outside was 37F and the fuel in the tank is about six weeks old and has Sta-bil added. The onan has 155 hrs on the meter. So, what might be the reason for the backfire?
When my onan started backfiring it then surged. Later it would not start. In my case the exaust valve spring broke causing backfire start up then surging. Then the spring lock fell out causing a no start. This happened weeks apart.
