That "numbers go up" thing got me, too, Roy. A better way to state it is that when your engine is installed on the aircraft (horizontal) the numbers stamped on the connecting rods/caps will be on the top side of the rods/caps (facing "up"). Has nothing to do with the numerical order of the rods/caps. Also has nothing to do with which way the #'s are oriented as long as they are on top of the rods/caps. Some of mine faced "forward", some faced "aft"... but all were on "top" of the rods/caps. The order should coincide with the cylinder #'s embossed on your crankcase or as called out in the overhaul manual. On my O-200, #1 is closest to the crank/cam gears on the "back" of the engine (or the "top" if you have your crankshaft bolted flange-down on an overhaul stand). > The crankshaft was bolted flange-down to a overhaul table=2C and all the nu > mbers were indeed going up. Yup, sounds like you got bit by the "up" comment. If the #1 rod/cap is nearest the prop flange then you may, indeed, have them installed upside down. Check the crankcase/manual for the proper order. > Can anybody on this list look at the attached picture and advise if the rod > caps are all supposed have the oil hole going the same direction? As anyo > ne who has rebuilt the "A" series engine knows=2C the rod bearings have a n > otch in them=2C so that they can't be installed incorrectly. Can't see the pic but each oil orifice should point to the adjacent connecting rod (1 to 2, 2 to 1, 3 to 4, 4 to 3). If you want to send the pic directly to me off list I'll have a look (... and I'll return pics of my O-200 crankshaft if you're interested). Best of luck with it, Roy.

I've got the graphs from the Continental manual but they are less than ideal for actual operation. I'm looking for a decent power chart that shows % power at various altitudes with RPM, MP & fuel flows. Anybody have one they like or a source?
