I was mowing for the first time this season and after an hour, I noticed a small amount of smoke, liquid spray from near the carburetor area. I noticed a hose had popped out so I reconnected it. This hose connects the engine block to air intake tube and I believe it is called a breather tube. This hose has a part inside that looks like a plug with a small hole.
I checked the oil level and since it was low, I added a bit to just below full. I restarted it and that’s when it started blowing blue white smoke out of the exhaust. I checked the oil dipstick and it smells like gas.
Mower is a Sears 46” 21 hp B&S. 10+ years old.
Any suggestions on how to troubleshoot and fix would be most appreciated
