Free and travel distance make it worth it, even if just for some parts.
Good luck and post what you got after you get to look it over more.

Think I saw it was a magnaciter, that's a nice find.

Looks like it may be wet from rain , no tarp. I'ld dry out magnaciter and genhead for a week or more in a warm dry place before running it. Or put a flood light on it for that week to keep it warm and dry it out.

Made the LONG distance trip with my oldest son to retrieve the generator.
First picture hour meter 203.6 hours
second picture I filled the exhaust with diesel fuel (better than more water)
This one is probably a parts machine... Time will tell.

Can anyone tell me the thread size for the exhaust so I can put a plug in it?

I believe the exhaust is 1-1/4" standard pipe thread. Why are you filling the exhaust with diesel? Is the motor stuck? I bet it is nasty in the cylinders if they filled up with water? Did you drain the oil and if so what came out besides oil?

p.s. Did you use GPS for that long trip of 1 mile round trip?

If you can drain the water and oil out and see a clear separation then it probably has not been run with the water oil mixture . That probably means the bearings and top end are ok but the pistons and rings are rusted. Boring is not out of the question as oversize pistons are somewhat available. It is worth a close examination to figure out if it can be saved. If it can it is worth something and a very useful machine. You will have to do a bit of disassembly to figure out the condition of everything. I would certainly be happy to get a machine like that for free. Cheers Dan
