Think I just bought me an 1811

Just out of curiosity, does that look like some minor scoring to you guys? Again, this is my first time opening a small motor like this so I'm not sure. I know no motor is going to be perfect after 30+ years of operation so maybe this is somewhat....."normal"?

Almost looks like a hole in the top of the piston?

When a head gasket blows, it should leak compression "air". If left blown for too long, that cylinder not able to pull its own "weight", that cylinder will start to let oil blow by its rings. I don't see any scoring on your cylinder that would indicate a broken ring, but it shouldn't have been pushing that much oil past them. Chances are good, that even after you put it together, its gonna burn oil. I have seen engines that were able to re-seat their rings...... but not always. Roll the motor and make sure the valves are working properly. As far as how it ran before, it may have started good, but it had to have a missfire.

Clean it up good and put it back together. I would put a lot like almost full bottle of marvel mystery oil in the crankcase and let this thing run and see what happens. Adding the mystery oil will highly increase the chance of the rings to reseal. Been there done that sometimes it works sometimes it don't. On all my small engines after every oil change I add some mystery oil.

Thanks Johnathon! BTW, I hope I didn't come across as smart-a$$ or anything in my other post and if I did, I apologize; understandably, I was frustrated. Anywho, I got things cleaned up as best I could and got things reassembled about an hour ago. I had to run into work for a couple hours, couldn't pull the whole day off, but when I get home, I'm going to fire it up and see what happens. I'm usually a very optimistic fellow, so I'm hoping for the best

Oh, one thing I noticed; the new gasket I got from O'Reilly's seems a lot lighter than the one that was on the motor...different material or something?

Thank you, I'll give that a shot. I actually just picked up a new bottle of MMO when I picked up my new gasket so it must be a sign

I always run a couple ounces per gallon in my gas for my small engines but don't usually put it in the oil. I'll give it a shot.

On every small engine that I own I always add Marvel Mystery Oil to the oil, and I add Sea Foam in all my gas. Some people say that it's a myth and it's just snake oil but I totally disagree! I also run non ethanol fuel in all my engines

Remember to retorque a couple of times after you bring it up to operating temp, or you will blow that new gasket.

Good tip. After I started it for the first time, I let itrum about 30 minutes at half throttle then went and pushed some snow at about 3/4 throttle for 15 minutes then paarked it and let it cool for a couple hours. Once cool, I retourqed them. I also plan to do it again after tomorrows big snow push

Well here's a quick video of the first startup after the head reinstall. Keep in mind that not only had it been sitting for several days in -20 weather but after this video I had to regap the spark plugs (had them at .25 instead of .35) and adjust the carb as it was running pretty rich at the time. Guess I'm at the juncture of time will tell now. Tomorrow is the big test as I'll have tonites big snow storm to clear at work (projected at a total of 4-6 inches) as well as several driveways along the way. Wish me luck, I'll report back tomorrow.
