Well problem finally solved. Turns out I had a bad wire connecting the magnetos together. I tried replacing the wire with a regular piece of wire, didn’t catch there was a diode in the original. Ordered the wire from B and S, engine started really after a few seconds. Also had a bad fuel...

I’m gave up on this project and took it to a mechanic friend last week. He noticed that the entire flywheel seemed to be magnetized. I checked on another mower engine and that’s obviously not the case. Is that normal for the B&s vanguard engine? What would cause that to happen? Should I get a...

OK, I will try spraying some carb cleaner in the intake and let you know if that works.

With mowing season behind me, I took a couple months off from this problem engine. Started back on it a couple of days ago. Let me recap as I am still having no success. B & S 386777-0111E is the model. 168 hours total time. Original problem was a blown head gasket. Replaced the blown...

Left cylinder was leaking oil on exhaust. Thought it was coming out of the valve cover but it was head gasket with a piece blown out. Did both of them while I had it apart.

My model number is 386777-0111E if that helps anyone.
