RE: Breaking in 215 radial?
Danny,
YIKES!! Get off of the non synthetic Lawn Boy ASAP!!!
Go with Yamalube 2S or Honda HP2 at 32:1 for the life of the engine! You should never run a totally non synthetic, especially Lawn Boy Ashless through the RCS 215 or any RCS radial!
Engine temp and prop selection is fine.
Thanks,
