When you measure your piston wash, do you hold it WFO for a 1/2 mile or so and then hit kill switch, continueing to hold it WFO and pull on brake and then pull plugs and look at them and wash? That is how I have been doing it in past and just want to see if that is how all of you do it. Or, once I hit kill switch can I let off of throttle and just hit the brake? Thanks. Also, how long of a run do you usually make, 1/2 mile, mile, ????
