Got the wifes 782 our for a bath that it needed desperately and pulled the motor.  There is a leak coming from some where, so the block was caked with dirt pretty bad.  Also, fuel pump diaphram was failing and leaking into the block so a new fuel pump went in.  Started with removing the tin and repaired the starter, which had gotten loose, with a few washers and lock nuts.  Got a roll of gasket paper and cut out some new gaskets for the valve covers, which is where I hope the leaks were coming from.  Hoping to get the oil changed today and give it a test start to see what happens.  We went completely through this motor many years ago as our first 'learning' experience with engine rebuilding.  Pretty sure I had this motor apart 3 times to get is close to being right.😉😆  The plus side was taking the plugs out of the engine yesterday and seeing that they were completely clean.  It appears to have been running well other than the external oil leak and fuel pump failure.  I know, I should go electric on the pump but the mechanical has worked so well for so long.   One of the tires has a bad valve stem, which will be headed to the tire shop for a new stem and reload of beat juice, now that I think about it........ Hope to have it up and running with fresh fluids this next weekend.  The hydro fluid hasn't been changed in years but honestly it might have 20 hours on it at the most.  I haven't bought filters for the hydro in forever, hope Cub still makes them.😁

Will you be able to mount the external filter somewhere so that the side cover goes on? 

That looks like something I'd inadvertently kick off.

I bolts to the firewall right under the throttle/choke cables on an angle.   Clears the side sheet nicely.

It really does, had it apart 3 times to get it right though.  Several things I would do differently after getting all the way through it now.

I like the boxer twins, but they do take a little bit of finesse to get back together leak free.  M20 is a HORSE on the plow.

Have one torn down right now (case leak...I think).  Starts going back together tomorrow 😀

Nice!  I'm hoping I got all of ours taken care of on this go around.
