Advanced Nitro R/C Engine Break In

A controlled wearing-in or seating of the piston and sleeve. The theory of this process is to seat the piston and sleeve at normal operating temperatures with an excessive amount of oil (by using a full throttle extremely rich mixture). Both low and high engine speeds are avoided as well as any sudden changes in engine speed (blipping of the throttle is not recommended during break in) www.ezrc.blogspot.com | www.elingsraceway.com
