o-235 break in procedure and cooling

Postby mcurcio1989 » Wed Mar 22, 2017 1:03 pm

The engine has fresh rings and honed cylinders (lapped the valves as well. I know what the lycoming manual says to do as far as a run in and break in period but their procedure is set up for a test stand with a test club prop and then an airplane in tractor configuration with a cowl and baffling. SO - I'm wondering what you guys would recommend I do for initial break in on an airboat. I do have CHT's and EGT's on all 4 cylinders. Thanks

make sure u fill it with oil, and go frog all night for a week. it will b broke in. lol

vari the rpm's on the first tank of gas. once the rings set good and it makes several hot/cold cycles to set the gaskets, it's game on.

when I buy a lawnmower I just go cut grass.
