Thanks JacksBoy, at least were not as bad as Iowa, I coudnt imagine that. Chryco thanks for the input! I have set of outside mics. But not a mic that takes inside measurements. Is there such a mic that does that at a resonable cost? Thanks! BTW, Chryco, or anyone else, is there an easier way to remove the main caps? It took me almost an hour and I 'slipped' and dropped a main cap thru the bore onto the "cardboard pad" I placed on the ground below my stand, Whew, it could have been 'gouge city' for the crank journal or cylinder bore,(glad I had the adjoining ones covered in anticipation of such an event. I thought about drilling and tapping the Cast Iron Caps but hesitated, in fear of potential stress cracks?
