no push rod manual adjustment on stilo selespeed. Its all automatically adjusted. Yet, you may need to do End of line calibration test in examiner (or Fiatecuscan) and specially the clutch degradation index test. solved my stated problem described on first post.
Stilo abarths selespeed push rod distance was measured to be ~15.5mm on two different cars. Nothing like the 28mm from Alfa selespeed.
My pump is working harder though. Used to be 2 minutes between each prime. Now is about 40 seconds.
