Silver serfer--- Guess i must be lucky from what you are telling me . I have had gassers on rubber mounts - the way i mentioned a couple of letters back - for 20 TWENTY years now & never a problem , I have & had Q42, Q52 , Sachs 3.2 , G23, g26, 2 G62 currently , so thats a load of rubbish you are saying . Obviously one has to do a decent job of mounting , not on made up rubber mounts .
