This is most probably a well worn topic by now, but I keen to here from anyone regarding the best way to run-in a Nova Flash .12. I would normally give the car two tanks on the bench using 15% castor no nitro and then run the car on the track with a rich setting for about 6 tanks then start leaning it out. By about tank 10 I would switch to race blend fuel and continue till race tune is reached.
One of our most experienced races prefers to do 1 tank on the bench ( race blend fuel) then tune the car just off race settings and run for approx 10 mins using the throttle to hold the engine back ( rather than a rich setting). After that it's tune to race settings and drive the car.
What procedure are you guy's using out there, that gives a well run-in engine, good power and longevity.
