AFM,
I've seen your posts about breakin procedures for EVO2 engines. What about non-EVO engines like the original 12TRP black head? Is it the following steps described by you correct? -Wilbur

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 4 more tanks, leaning HSN little by little until you end up with nearly at general setting on the HSN.
My EVO2 ended up with full power, and running like the Beep-Beep Bird with 5 3/4 out on the HSN and 3 7/8 out on the LSN, and at that point it is flush with the slide end.
Hope this helps
