I did mine this way.

To use the wide open throttle method, the engine should be tuned extremely rich. Before starting the engine for the first time, wrap the head in a few layers of Aluminum foil, or layers of a sock. Use natural fibers socks like cotton or wool - artificial fibers could melt. Either have the car on a starter box or a piece of wood so the wheels don't touch the ground. Preheat the block of the engine to ~200F/93C, then start the engine. Pull the throttle slowly to wide open throttle, making certain the engine does not clear out. It should be 4-cycling and the wheels should barely be turning. Add heat to the engine with the heat gun to keep the engine over 200F/93C. Run through the entire tank and let the engine cool with the piston at bottom dead center, otherwise it could get stuck as the cylinder contracts. Repeat this process four times, then remove the foil and lean the high-speed needle so the engine is only slightly rich. Run gently for a tank or two, then tune for performance.

5-6tanks


then

You get the car up off the ground and let it idle to 160F. Once it gets to 160, you richen the HSN 1-2 full turns and go WOT. The massive amount of fuel and oil will cool the engine to 120F. You then put the needle back to factory and let the car idle to 170F. Once at 170F, you richen the HSN 1-2 turns again and go WOT until the engine hits 120F. You repeat this method for 180F, 190F and then 200F. Once you finish the cycle to 200F, the first part of break in is done. Then you get the car on the ground and run it. You start carefully tuning the engine up 1/12 turn on needles at a time very slowly, carefully controlling the temperature and making sure temp stabilizes before you tune again. You repeat this until the engine is tuned where you want it. You basically run the whole break in with 8 tanks of fuel and basically without ever turning the engine off.


for another 5-6 tanks..

took about 1/2g...I just need to break in the other 1/2 at slow easy throttle pulls .then ill start race tunning..

first time doing it like this..so far so good.
