Techumseh Break In

I just swapped out the clapped Tech HM80 in my late 70's Simplicity 828 with a new old stock Tech HMSK100. I've never actually owned anything ever with a new engine in it so am totally clueless about what to do to go about breaking it it. What kind/weight of oil should I use? What level of throttle should I run it at? How long do I need to run it? It seems to be a reasonably late production model but not sure what year it was made. I can look up the serial if that makes a difference.
Thanks,
alfredk

Run it full bore for 5 hours with non synthetic motor oil. then after that you can run what ever kind of oil floats that your boat.

+1 on breaking it in under load.

I have never owned a new engine either!
What exactly is the goal of the breaking-in process? what does it do for the engine?
and would it be bad if you just starting using it normally, and didnt do the break-in procedure?

thanks,
Scot

A new engine will normal "dirty" up its oil with any metal chips and shavings from the manufacturing process. The idea is to avoid having these pieces flow around for longer than they have to, so you want change the oil earlier that one time. The varying loads idea is to avoid it wearing-in in one particular set of operating conditions. Varying speeds and loads helps in avoiding this.

It is meant to seat the rings in the cylinder. if you ran syn oil from the get go nothing would get seated right. and then you could end up with broken rings, blow by or a bottomless engine. after the 5 hours you drain the oil and you can see all the shiny silver stuff in there.
