Today I picked up this 30+ year old Toro
Model: Toro 724 - 38050 Ser 9000953
Engine: Tecumseh H70-130176D Ser 81320
Connecting Rod: Tecumseh 32591C eBay: $18

As you can see, the case is cracked where the electric starter used to be.
The previous owner salvaged the starter for his other Toro. He was running it last week when it suddenly started blowing smoke and seized.
I have zero hands-on experience with 4 stroke engines but have watched lots of videos lately. My best guess is that the connecting rod shattered.
If that's true, a generic replacement is about $18 shipped on eBay.
Question: can JB Weld be used to fix the crack in the crankcase cover. I am hoping it should be fairly low pressure and reasonable temperature in there and that all it needs to do is seal well enough to keep the oil in place... does that sound about right? I've seen videos of people doing that and posted one below.
Any opinions would be welcome.
