Hmm...... this sounds like something I may have to do as well. I am trying to build an A7 Shooting Star virtually from scratch, having done the same thing with an A10 a couple of years ago ( can I put a picture up ? how do I do that, someone ? . Anyway, I have acquired a decent crankshaft, which apears to need only its first re-grind, but I was wondering how to remove the sludge trap plugs, which have been well and truly popped in ( 4 or 5 punch marks around each ). I am not worried about originality, so am quite happy to buy the new type, with allen heads, but have I got to destroy the old ones to get them out ?
Any advice from some of you Oracles out there would be most welcome.
