They say , at least Initial Dm that he does that because that way the piston and sleeve ends up polished.
What I normally been doing is the first 1 or 2 tank at idle and then start to run the car very slow with blipings to get it to 200 and then let it cool completly this for about 10 tanks each tank increasing the throttle, once I get to WOT I start to lean it.
Right now I have gone through 1 tank at idle very rich for 2 minutes cycles and then turn it of, it get to 170 ,I think Ill do this for one more tank and then put it on the floor start the blipping until 200 turn it of to cool and again for a few more tanks, I have all this week to do this and the next to set the needles.
What do you think of my method?
