About 4 turns out form closed. 2mm from flush sounds about where it was. LSN was 5.75 out from closed with the slide pulled out.

Yeah always ran 185 to 195 after I learned in the very beginning this motor's massive head deceives the temp. I also learned it would flame with a rich bottom, and would let you lean it out to a sick lean bog on top before I got to 240 temp range. I never had to move the needles more than 4 hours. More like 2 max either way.

Not sure why the bottom of the piston litterally fell off, but it did.
