Hi Test,
Why don't you try the engine forum. Last time I looked ,there had been 357,715 posts .I am pretty sure if you go there ,you will find what your looking for. My break in procedure ,I run the motor on a break-in mount clamped to my picnic table. Normaly I will run three --12 OZ. tanks of fuel through it at 1/2 to 3/4 throttle with the occasional full throttle slighty rich. I never run it at a fixed throttle setting for more then 25/35 seconds. In the box (If you still have it)are excelent instructions on Prop size,fuel nitro/oil content. If you don't have the box-try meccoa eng site. www.modelengine.com or the thunder tiger wrb site. Good Luck--
