It's been outlined to me that nearly all engines be run WOT to break in [almost] all engines. Tapered bore engines run only slightly rich whereas ringed/lapped engines get the 4-stroke rich break in. I run all of my engines at WOT, but the non-tapered bore engines get run 4-stroking for the first 5-10 minutes and over the next hour or so gradually leaned. I usually burn close to a gallon on ringed and lapped engines on the bench.
I have several break-in videos on YouTube of my break-in regimen.
As soon as I square up in this G51, I'm looking at getting a Fox .60 and maybe a screaming banshee .35 (Jett BSE) for my birthday presents to myself.
I'm hoping my Son's first word is 'nitro'.
