"the break in bible"
#271

To be honest, there are 1001 methodes how to break in an engine and all are basically the same: start rich, keep te performance down and work slowly over 1 or 2 liter (depending the starting pinch) to a race tuning. With cheap engines I have done plenty of the quick and dirty way and have broken in several engines within an half liter and the results were also good.
Now for me, I have made 2 break in machines so I do de most work at home.....

Do not get fooled by different results mentioned by others. All engines do come with small tolerances so that one is faster than the other or keeping its pinch better are most of the time caused by tolerances and choice of materials.

I agree, there are so many methods out there that I have probably never broken in engines the same way twice!
Heat and lubrication is all that I'm concerned with, but of course that includes several other things by default.

Ok...thx ...will give the method described in the first post a go, cooling down in between 2 to 3 minutes stints and trying to keep the temps up, not too rich, not too lean, not reving up to high

In the case of a centax type clutch it is wise to loosen the spring a bit for a low rpm engage.
