12 psi dyno run for 140hp?
#45
Unfortunately, I have not gotten to try to correct the issued I have been having with the Miata until today (hoped to do it 2 weeks ago). I was checking the timing and it seems WAY off. My idle is high and not the most constant, which I am sure is not helping. I am posting a (blurry) picture showing where the timing mark I found (and then added whiteout so I could see it) is, compared to the stationary marker.
Any thoughts:

Heh. I'm guessing you're not actually idling at 50° BTDC.
Pull the #1 spark plug. Place the oil dipstick down the hole. Rotate the crankshaft by hand (well, by wrench anyway) while observing the up-down motion of the dipstick relative to the mark on the pulley. Ideally, the dipstick will reach apogee when the mark on the pulley is at 0 (or T) on the indicator.
If this is not the case, then the outer ring of your pulley has slipped relative to the hub.
