Hi Paul. My '83 Sud runs a cap at 7lb but a S2 33 may be higher. If it lifts a 7lb cap I'd check is there water inthe oil or oil in the water before going to a higher cap. Compression check.....
I needed some info' on my Sud earlier,normally I would have posted on ao in the Sud/33 lounge but wondered if I'd get a reply. Instead spoke to Kev on the phone - job done. Cheers Kev. Tony.
