Sorry for the re-post, never got a response to my last question.
It's cold outside, 15-20 degrees Fahrenheit.
Need to break in a new OS built ABC buggy engine.

Any problems doing it in the cold?

Not a bad idea, this would help the engine get up to running temps sooner.
Remember... when you're breaking in an engine, you need the piston and sleeve
to loosen up a little, while keeping a good fit through the heat range.
When an engine is being broken in, it is important to HEAT-CYCLE the piston and
sleeve. To do this, the engine has to get UP to running temperature. Out in the
cold, this can be tough.
Just run the engine till it gets good and hot. If you have a temp guage, much
better.
The trick is, to get the engine up to temp, rotate till the piston is at bottom
dead center, cool down, repeat.
So the engine cools down a little slower, I would run the engine, bring it
indoors to cool, then go outside, and re-start.
Repeat this process several times (at least 6-7 tanks.)

Thanks all.
This is pretty much what I had been thinking.
Looks like we all agree.
