All clear!
Found the data needed for measuring, only the manual is not really clear about the clearance.
Under the initial clearance there are several values specified
for the ST engine.
We have :
Fire ring gap
0.70 mm
0.41 mm
0.55 mm
Compression ring gap:
0.55 mm
0.26 mm
0.40 mm
Scraper ring gap:
0.65 mm
0.36 mm
0.50 mm
(http://www.winget.co.uk/document/LISTER%20ST%20WORKSHOP%20MANUAL.pdf , page 125)
Since there are just 5 rings, the values make no real sense to me as a layman, or I am misinterpreting the values. In the SL manual (the other engine I have) the values are more clear "Between .20 and .50 mm".
Any thoughts on this?
Thanks again!
