How many hours do you consider a MM engine to be running at full strength?

    After how many hours is it considered "broken in"?

    I'll get flack for this, but my answer is 1 hour. I never saw any increase -it was fast from the start :)

    When I first crank it up - ain't never rode a lawnmower around the yard to break it in - they run forever and in alot worse condtions - dust, heat, etc.
    I even asked the Briggs rep in La. if the big blocks pick up power/speed after a certain number of hrs - he said not really - you might see a couple of more rpms, but that's about it - really don't know where the basis for this "theory" came from.

    I ran mine hard from the start, but did notice a slight performance increase at seven hours and around 15-17.... I don't know why, if it's the cylinders smoothing out and valves seating in completely, or what...but you could feel/see it. :)

    I can't say if it is the motor or the driver, but it seems the kohlers smooth out a bit at about 10 hours and again at about 20 hours, I have heard this from alot of customers as well. I am not sure if this is real or just comfort level with customers. I don't think there is much power increase and I think the RPM increases are due mostly to wear and shining up the props (that first 10 hours you just gotta run it through as much junk as you can to see what it will do, everyone does it). I know with the PD's over built props, they do seem to run a little better after some initial wear, so it might be more with the prop then the motor.
