'74 C160 Tecumseh engine tractor. Let's put it to use!

[JCM 9,130]

Nice tins on that 160.I remember she didn't roll out all that easy        Nice job so far with that one EB.

@JCM

Thanks Jim. 

Should be able to get a little more done today. 

We have a bunch of firewood to pull from the forest and I'd like to be using this tractor.

Looks like a couple nice old wooden boats too…

Oh there were FAR more than "a couple". 

 

He had unbelievable amounts of boat cushions.

Boat gas tanks maybe 5 to 20 gallons that set in the boat for an outboard... Seriously at least 50. 

Wooden or fiberglass boats?

@JCM ???  I don't remember... At least 7 or 10 there in different places. 

File cabinets.. 10? More? Paperwork. Wow.  

Sooooooo much more.....

I wonder how much more power the OHV has over a normal flat head engine?  It would be interesting to test two similarity fitted tractors out next to each other!

Exactly why I want to get using it !! 

 

It makes the same HP at the same RPM. 

Torque is lower on the Tecumseh engine. ... But....

It's with a much smaller engine. 

 

A Kohler vs Tecumseh comparison. 

 

Both are 16 HP @ 3600 RPM. 

 

Peak torque & cubic inch are the differences. 

 

Tecumseh:

Displacement: 27.66 cu in. 

Cylinder Bore: 3.50"

Piston Stroke: 2.88"

Max Torque:

25.1 ft-lbs @ 2800

 

 

Kohler:

Displacement: 35.9 cu in. 
Engine Bore: 3.75"
Engine Stroke: 3.25"

 

Max torque: (from a Cub forum)
28.25 ft-lbs @ 2600

 

That's a difference of about 11% torque and nearly 30% cubic inch. 

That's a lot of extra volume to fill. 

It would be interesting to see an actual true to size equal comparison.  

 

Sooo.... How often do we here  REALLY use peak torque??
I'm super curious to know if I can feel it... at all? On big hills? Pulling heavy loads? Never?

That lower displacement equates directly to lower fuel consumption!

[Oldskool 6,643]

That's going to make you a real nice "stuff hauler".

 

[ebinmaine 67,409]

I've spent some time checking over the wiring and general condition. 

This afternoon I put a battery on the fender, a new spark plug, and turned the key. 

This engine will fire with a spray in the carb but the fuel pump wouldn't pull anything.  

 

I removed the fuel pump and carburetor to clean and inspect.

The carb looks recoverable but the fuel pump may be more trouble than it's worth. Those one-way valves look iffy and that screen with the gasket edge are, I suspect, irreplaceable and I can't imagine it being worth your time to try to fabricate one.

[Snoopy11 5,714]

Eric... pal...

 

Okay... no... just.... no...

 

THAT is... simply not the correct terminals for 'dat battery...

 

 

Me thinks you could use some of these or... something...

Whassamattawiddeez??

 

Other than a slight (total) interference with the clutch pedal it's ... Well maybe I'll change it.  

 

That's not the battery that'll end up in there anyway. This tractor can and will use a group 51 51r.

Agreed on both counts. 

The fuel pump is interesting to look at but beyond practical rebuild. 

Carb ... I think... Is usable.

Lookies like a parts order... is......in order.

Yessir. 

I didn't look to see if I had a rebuild kit for this carb yet. I want to get the Welch plug out of it so I can make sure the internals are all free.

For the fuel pump I may go with a replacement vacuum pulse type or maybe even electric.

What procedure do you use to get those little buggahs out?

[ebinmaine 67,409]

One can use an awl or small punch and put a few indentations in the middle which loosens it up on the edges.

Sometimes by taking that same sharp awl you can scrape around the outside of it and loosen it up some. 

[ebinmaine 67,409]

Installation works pretty good if you have the right size punch. If not you can use a socket to drive it into place. Doesn't take much pressure.

I've been thinking it would be neat to have this rig going up to Owl's Head show which is next weekend. 

I'd need to clean up the wiring a little and install an electric fuel pump amongst the other known issues.  

 

Here we can see the PO repair for bypassing the PTO switch. 

 

It was wrapped in electrical tape...

 

Today I modified and installed a battery hold down. Also changed the solenoid which I discovered had a loose small terminal when I tried to remove the wire from the ignition switch. 

I didn't have a carb kit in stock for the LMH (big) carburetor. 

Because of that I wasn't able to remove the side welch plug and clean behind it. 

 

 

I did clean it out what I could.

Installed the carb. 

 

 

 

 

 

Fired it up.. 

It'll run for a bit... Make some fun popping sounds... And die out. 

I believe the carb is still gunkified internally. 

While messing with that the starter began acting up. The Bendix has of course been setting for (decades?) And isn't overly willing to move right. Not disengaging when I let off the key. 

So I pulled the side cover off the engine to see what's happening there... 

We had a talk involving brake clean and dry lube. Now it'll disengage if I make the engine turn completely several times. "Bump" the key and it sticks. Good enough for now. 

While in there I cleaned a few insect nests off the flywheel. 

Today I'll check the pin to ignition coil gap. Finding that the longer pin should be around .010. 

Then get the side cover put back and see about putting a Kohler Carter #30 carb on it.  

This is the carb that was on the original C160 Kohler engine that eventually became Cinnamon Horse. It was very loose and the top linkage was broken. At one point I had tried to hold it in place with solder but couldn't get it hot enough. It needed to be brazed. This time I used J. B. Weld Quick set. 

 

 

If it runs better I'll likely just set the RPM to something at a very high idle. I probably won't have time to create a linkage to the governor but that'll do for show purposes.  

 

[Handy Don 12,210]

@ebinmaine

Gunkified internally (as opposed to externally!) and a black tape-wrapped PO PTO switch bypass are my favs for the day.

 

[ebinmaine 67,409]

I want to begin this post by advising the No Picture Police that I forgot to get pictures...

 

I did get a few minutes three or four days ago to swap out a carb from a Kohler 16.

The good news? It does run better.

Not great but better.

It was good to hear the engine run by itself and seem reasonably close to happy.  

 

I'll get the original carb soaking and get a carb kit and see if I can get it to be a runner with that one.

Ban that SOB Mike!

I support the No Picture Police! He just ignores the rules and thinks they don't apply to him

Well ladies and gentlemen I've had a second or two to get back on this carb for a second or two.  

 

I popped the Welch plug out. Soaked it for 2 days sprayed 2 full cans of brake clean all around.  

It's definitely cleaner in a noticeable way.  

Next week I'll order a carb kit and see about getting the Tecumseh back to running. 

I did find something rather disconcerting...

Notice in the pic below the choke flapper is contacting the little nubule inside the carb. 

WTH??? 

 

 

It won't allow the choke to close because of that.
