I have what I believe is a new, unstarted Tecumseh HH100 that my father in law bought at a sale of some sort many years ago. I've had it since I cleaned up his estate 12 years ago. Recently I decided I had lugged it around long enough and decided to find out what it had been manufactured for.......only to find out that many brands had used this engine? From the serial number (4135E) I think it was manufactured in 1964?? The model (HH100-115202D) should tell something about the application but I need help in finding out what that is. At one time I thought it might have been slated for a John Deere 112 but they didn't use that engine till 68. Also it has a Walbro Auto-Pulse fuel pump which would indicate a low or remote fuel tank. Sears? Massey? Cub? Military? Can anyone help me identify this "Whazzat"?

If it was made in 64 it's not for a massey or a deere.

4135E Could be 1964 OR 1974

 

1965 Sears Suburban 10 was the earliest Sears GT to use the HH100.

Is it a Points engine?The really early Tecumseh HH100 engines had points.Later they went to a 1 piece Aluminum Mag then to a 2 piece Mag.

 

Both of my old Sears customs 1968 10xl and 1972 10E have the 1 piece Aluminum mag.Both also have a Walbro Pulse pump.Even though the Gas Tanks are higher than the Carb.

 

 

The older Tecumseh Points engine will have a cover like this one does.

The points engines are worth a bit more IMO because if the Mag happens to burn out you can just use an automotive style Coil instead.

Wow....you folks don't waste any time! Posts on other sites went pretty much ignored. To answer some of your questions: I just pulled the cover off the flywheel and it has a one piece solid state ignition. Also kinda confirms the "new" guess as the teeth on the starter don't look like they've ever been engaged. I will get a pictuure or two up tomorrow. Anything you'd like to see in particular? It's got about 30 years of dust on it....should I clean it up first? Thx for your help.

I want pictures!

 

A NOS Tecumseh cast iron big block engine is something that does not come up every day.

 

I'd be more inclined to give it a stamp of 1974 since it has the solid state ignition instead of points.  As far as what it was used for, you have to remember that Tecumseh also sold "generic service engines" just like Briggs and Stratton does now. 

 

If you take a picture of the crankshaft, that would help us determine what the crank COULD power.

I could have sworn I posted a reply, but I must have forgot to hit the "post" button (my head is a mess).  NICE engine, and SO rare to find!

I'm a sucker for a Tecumseh engine.

Very nice find. Never seen a new hh before

I have found two NOS engines. HM80 8 HP(with light coil) that went on my super Bronc and a hs35 that is still sitting in the shelf.

Well.....still not sure what this guy was manufactured to fit....if anything...was hoping someone had some sort of way to decode the model number. I'm not a restorer and it seems a waste to stick it in my weary JD112. Any ideas?
