Thanks a million, Aussie and Monty
Then I'll rebuild one of the nearly worn-out BTT's I got from a friend, I do break-ins for.
Got a 3 gallons (4,97mm north/south) old crank from the Plus4C Team engine with the defective head button, a new R7 rod in the pitbag and an 1 race old AVID bearings set in another engine case. The P/S has very little compression ratio but is without any scratches, so I'll send it to Raya for a resizing (haven't tried that before

) and buy a new wrist pin.
Life is good
