Had a break in the rain so I got outside and started into the Craftsman. Had already put fresh oil in it, plug was good. New gas tank and starter solenoid came in on Thursday so I installed them, put some gas in it, connected the battery and hit it.
Pretty much started instantly under the choke setting. Let it hold there for a little bit then backed down the throttle to mid way and it just took off in RPM. Put it back up into choke mode and it idled down. Held it there for longer and tried to get it to hold a mid range RPM. It kept idling to the limit until it started knocking and clattering so there went the rod bearing. Got it start again and that time it held a mid range RPM so whatever it was in the carb finally started acting right but the engine was already toast at that point. Held idle until it locked up. Yay carbs....

I walked away for a minute and got the other riding mower that I got that day since it was also a Briggs & Stratton engine. Rolled it up and looked it over, pretty much identical on the mounting point, exhaust port, starter, coil, and carb was identical, throttle linkage the same, so said yup and started into looking that one over. Drained the oil, pulled the plug, spun over nice. Same thing as the first the float stuck open and it was all full of old gas. Got all that out and prepped it for install. I wanted to use the Craftsman because it was in better shape and already put money into new parts for it.
Started tearing the Craftsman one down, drained the oil and it was full of glitter..
Pulled the engine from the other mower and got it ready for install..
Bolted it up, hooked everything up that needed to be hooked up, muffler & main drive pulley bolted up fine. Fuel line, wiring, throttle linkage all installed fine. Fresh oil in, plug back in, turned the key and it fired off instantly..
It held RPM under choke setting fine, went to idle down and it stalled out. So pretty much opposite of the first time. I couldn't get it to run right so I swapped the carb out with the first one. The old gas definitely gummed up the one that was originally on it. Put the carb on from the first engine and it started up under choke mode fine, this time I had mid range RPM when I idled it down so whatever it was decided to work. The joys...
Made an adjustment to the brake linkage so I had functioning brakes, and ran a few passes through the yard with it..
Worked perfectly fine. Not one hiccup. I'll have to do some research into what this engine exactly is..
Pulled the starter and coil from the engine that blew up and put them in a box, they are identical to what is on here. I put the gummed up carb in there too, I'll keep it as a backup incase I need it. Saved the deck belt from the other mower. My next day off I'll go through the wiring and clean it up, di-electric grease on all connections, secure moving parts that could wear out like the fuel line, etc. I put the other mower chassis with the blown up engine and everything else not needed on the curb for the neighborhood cleanup crew.
Not too bad for $100 in.
