Generator on my 216 almost rattled off the other day. Turns out the 2 bolts that hold it on underneath worked their way out. Any idea what the size and thread of the bolts? It is not 5/16 and seems to be too small for 3/8. Please help! I can't drive it until I have the proper bolts to re-attach properly!

Thanks,
Pieman

Which bolts are we talking? The ones that hold the bracket to the block or the ones that hold the generator to the bracket?

I'm going to make a reasonably educated guess that in either case they're 3/8-16 bolts.

The bolts that hold the generator to the bracket are 5/16". If a 5/16" bolt is sloppy, then the holes in the generator end frames are worn. In In that case, drill the bracket and the end frame out to 3/8" and don't let the generator get loose again. I like to use Nylock nuts or jam nuts in places like that.

The generator bracket to engine block is 3/8-16. When the other ones warble out, you can put a nut on the back of them rather than rely on the threaded holes.

There are no threaded holes except for the belt adjuster bolt hole in the front bracket. The pivot holes in the generator end frames are not threaded, and never were. That should be common knowledge for anyone who has worked with these engines on a regular basis. The original-equipment pivot bolts had close-fitting unthreaded shanks through both items, and squashed-thread self locking nuts. Chances are those items have been lost many years ago. A good substitute might be 5/16" Allen head shoulder bolts, or 3/8" shoulder bolts if it's necessary to drill the generator end frame and bracket.
