Start the engine with the general settings. After it is running, open the HSN 1/4 of a turn at at a time until the engine starts to load up, then turn the HSN in 1/4 of a turn in and let in run at idle for at least 1 tank. The idle must be even, if rpm's go down or up, close or open the LSN 1/8 th of turn at a time. Let engine cool completely after first tank, and make absolutely sure piston is BDC during cool-off. Repeat this 4 more tanks and your "heat cycling" idle break-in is done, then it is time for track break-in for 5 more tanks, leaning HSN little by little until you end up with nearly at general setting on the HSN.
