Strange thing happened today
Before using my snowblower today which has a GX390 engine. I decided to look at oil level. As this motor dosen't take oil, I never checked it between oil change. Big surprise ! The motor was totally overfill with oil and... gas. Two weeks ago, I had a problem with the carburator. I lost near half tank of gas under the carb during a night. (stick float ) During this problem, fuel went in the oil and there was near 1 liter of gas in the oil. I perhaps used the snowblower in this condition one time. Last time motor didn't seems to have the power it normally had. Today, I used compressed air in the carb and changed the oil with Mobil 1 I always use in this motor . Everthing now seems fine. I don't think motor was damaged and finally, I really think I was lucky. Now I will use the fuel shut off valve every time I use my snowblower.

Yep - you may have dodged a bullet. You could have hydro-locked the cylinder starting it, especially with the electric starter, and you may sill have hurt the engine from using a very thin oil - the oil/gas mix. Keep an eye out for anything strange.

Good plan on always using the fuel shut off.
Make sure the windows are up before the snow plow goes by !!
