Default Re: If Your New Motor Won't Start,

...and remember to properly seat the rings, you have to do it within the first few minutes of running.

Don't baby it.
Start off with about 1/4 throttle and accellerate for 10 seconds, then slowly slow down. Repeat this cycle a few times then start using half throttle and a little higher rpm, once again slowing down slowly (about twice as long to slow down as it did to accellerate). Repeat several times then start using short bursts of full throttle and go into the upper reaches of rpm, but don't strain it. Do this a few times and the rings should be seated. Let cool, then continue with break in for the next 3-400 miles.
