Hello, i am in the process of breaking in my new Nova .12 class engine. After i pressed the car on the starter box, what is the right procedure? rev up the engine? & for how long? Cos when i press the throttle, the engine die out a few seconds later. I do not know if i am running it too rich/lean. sometimes it takes a long time(few seconds) for the car to move. Then the engine dies again the moment i release the throttle. I do see a plume of smoke whenever i run the car. Do i look at the density of the smoke to determine it's richness? Even if the engine is too lean, is there any smoke? When do i know if the engine is already broken in? I have heard that the break in is very important. It will determine the longevity & performance of the engine. How do i tell if i have done a good job on the break-in? Please help me. Thank You.
