Charlie - sorry about that knuckly. Missed the spell check to make it knuckle, but the jist was right.
Jeff - thanks for the support. Us W/F guys gotta support each other.
Don T - and thank you for your support, but I suspect it allows you to include the off topic comments about the 1512 and a tea shirt (I assume that's a T-shirt with a big ole off-brown spot on it).
Terry D - sure does look like a terrific candidate for restoration. I see it has a hydraulic lift and a right-angle gear box with tiller mount. Can't quite see the 3pt but assume it's there. Any chance you can get us the numbers from the tail light lenses???? Would like to know if the end number is 70 or 75. Those things are nearly gold these days as well. Wouldn't be nothing wrong with sending the tractor and engine serial numbers, and engine spec to Art as well, and make sure you call out 13 FIN!!!!! I see it also looks like they left the cast lower part of the manual lift arm rather than instaling a rockshaft, which is a little odd since it wouldn't give you the cam so you could have a floatup and locked level.
Mike F - boy it's a shame when I re-read my own stuff and see typos, duplicated words. I gotta stop typing.
Brian W - yes I recall seeing that info by David Kirk, and it still surprises me. I have checked the parts look up before and no, there are no balance gears listed for the AQS engines in the Quiet Line series. There are however 2 styles of dip stick tubes used on the 12hp and 14hp engines. The older versions have a hole in the side of the block (just behind the starter) for a sorta J style mount dip stick tube. The later versions had a hole in the top of the block directly above where the balance gears would have been. The 16hp is only shown with the J style side mounting tube so Kohler must have only used that style block going forward, at least for an AQS engine. I've seen this block used for 1x8/9 series replacements. You have to block off this hole and use a cam cover dip stick.
Frank W - sorry to see you're having problems with the governor in your 1200. Hoping that Dennis will come back again and help with your questions. I sure hope you can fix it externally without having to tear into the block. I just don't know the details on the governor myself.
