Dar, don't take this personally but I didn't learn anything new from your thread. I've heard that story about damaging an ABC by running it rich long before you started even the first thread on it. I didn't believe it then and I still don't but until now I've never had the opportunity to find out for myself what will happen. Many's the time I've seen someone write in saying they've just run their new engine (always sport engines) too rich and you've immediately told them they've probably ruined it.

For those who still don't understand what I'm doing (and it seems you're one of them Dar) I'm not trying to say that the accepted method is wrong. Obviously it's fine. All I'm trying to find out is if running it very rich from new will actually cause damage to a sports type engine, my intention isn't to run it in.
