Doug, the 67's only used the starter/gen and points/mag ignitions for the 1st half of the year. After around the end of June, they switched to ring gear starter & solid state ignition. I do see points on yours don't I? Hard to make out for sure.

Yes you are right it has points, I don't think it is the original engine as it has 4 oil drain plugs, all the original engines have 1 drain plug I think, the ones I see in the manuals I have show 1 drain plug. I have some HH engines that have 1, some have 4, the ones with 4 have an extra tag on the engine, short block replacements I believe.
Mine is serial# 501202, 67MF12s went from 500001 to 502904, from what I can find out, so that would make mine made in the first half of the year??? So I would say your right S/G and points is what it should be.
I think when the engine was replaced it had an exact replacement short block put in, it's the only thing that makes sense.

I have never had the head off or the main shroud, only the cover for the s/g belt.
BTW did you hear the popping sound in the exhaust? What do you think exhaust valve seat a little leaky?

Could be the valves are a bit tight on clearance, or possibly a seating problem otherwise. My 67 MF12H is number 500044, and I've never seen an earlier one to date. Yes, yours was likely built in May or early June.

Great video's Doug! While it is fresh in my head... how does the speed range between the hydro & the gear tractors seem to match up? Can you still get the lo creep like 1st gear on the geared tractor, and still hit that 10mph top speed? It's snowing here and I moved a good 5" off the driveway, but I should grab a photo when I plow the path out to the wood pile tomorrow.

Top speed on both hydra and gear drive are the same, 9 or 10 mph whatever it is, the hydra will creep along same as the gear drive but the gear drive is better at holding a steady low speed than the hydra.

Thanks guys, this tractor was my first garden tractor, my favorite as you can see it's not nice and pretty, it's a working tractor. I've always tried to keep it in good working order as it's the one I jump on turn the key and expect it to do what ever it can. Right now it's in need of some TLC as the battery is n/g, choke cable broken, needs the back cushion on the seat and a few other little things. Because of the way it looks and works it gets neglected a bit.
This one is due for a good once over in the shop.

Another snow plowing video, we got about 6" over the last 2 days so I did another video.
I have a stock MF12Hydra, rear tires are empty with 1 set of factory wheel weights and 2 link tire chains. Plow is home made 4ft and aside from that this is how they came 44 years ago.
What you see here is about the limit of what I can do or push with this set up, I have a gravel driveway and if you go up against something that doesn't move the tires dig in to the point of almost stalling the motor at full power. Hydro's eat up hp.
If I had the weight on this tractor that "FirefyterEmt" does, 400+ lbs, with my driveway I'm sure the motor would stall out, and I'm sure it would push more.
I got stuck in the bank as you can see the Hydro is great at rocking the tractor to get out.
Somebody said here "boys and there toys"

Nice video! I forgot how quick these critters are.

I had a MF12H with a FEL 30 years ago and I don't recall ever stalling the engine pushing snow. But that may be due to old timers desease. They are a great little tractor and I just got another this past summer. I still have the FEL from my first one as well as the 3PH and back blade that I made for it. I smell a project coming up, after I get some other ones out of the way.

Who says if you haven't used it in two years, get rid of it. And why would you listen to them!
