I recently replaced some parts in my toilet prior to re-installing it after installing vinyl in the bathroom. I replaced the tank/bowl gasket, flapper, and the tank/bowl fasteners. The tank appears to have a small leak at one of the mounting bolts.

I'm looking for advice on how the tank is normally mounted to the bowl. I've tried using 1 nut on the bowl side, and also using 2 nuts (1 under tank & 1 under bowl flange). Which is correct? The toilet is an older American-Standard that drains in the floor.

Think of it this way: the tank connection to the bowl is not what seals the holes in the bottom of the tank. You seal the tank with the bolts, rubber seals, washers and nuts before mounting to the bowl. The 2 nuts (sometimes wing nuts) that hold the tank to the bowl do nothing else but hold the tank to the bowl. That is, they aren't part of the "seal" that prevents leaks.
On the inside of the tank you should have the head of the bolt, one rubber seal, and possibly a washer betwen the head of the bolt and the seal. On the underside of the tank there should be a rubber seal against the bottom of the tank, then a washer, and a nut. The tank is then placed on the bowl and the nuts attached to hold it on.
Hope that helps.

Yes, that's how it's set up now. The nuts that came with the tank/bowl kit were too large to fit in the holes in the bowl, so I had to substitute 2 of my own.

It may be that the smaller nuts are not covering a large enough surface of the rubber seal to make it "seal" properly. Try adding washers between the nuts and the seals.

Rlpxpxhfqsx is correct. Use metal washers the same or just SLIGHTLY smaller in diameter than the diameter of the rubber washers. Put the metal washers between the bolt head and the rubber washer to spread out the pressure and create a better seal. You should always put metal washers on top of the rubber washers when attaching the securing bolts to the tank, if only so that the rubber washer does not move while tightening the bolt (metal to metal will move before rubber-to-metal or rubber-to-porcelin, which is what you want). Otherwise, it will always leak.
