also, i ran the engine on idle for a couple of minutes then decided to switch it off, repeated this a few times before trying the high speed, is there anything else i should be doing for break in of new rings?
Try to avoid loading the engine up (running into long, thick grass really fast)for the first hour or so of operation.
After the first cold/hot/cold cycle, check for oil leaks and check head studs, blade bolts, etc.
After a rebuild, I usually do an oil change after no more than 1 hour of operation, and after that, as per the owners manual.
Enjoy!
