Worse than brass on brass, it's brass on cast alu on the HS carbs. This may have worked better with leaded gas (purely a guess? But maybe some evaporated fuel ended up in that area and helped?). Or they just never expected the Brit cars they were normally bolted to to last long enough for it to be an issue.
