Need carb kit for 1965 REO ST-268 Snow Throw

Hi,

Anybody here tinker with old snow throwers or Tecumseh engines?

Almost two decades past, my father-in-law was kind enough to gift me HIS father's REO by Wheel Horse Products, Inc. snow thrower. A mighty fine gift indeed when you live in the dreaded upstate NY snow belt, and it served well for several snowy winters. Ran and operated great when retired years ago in favor of a new tractor, but now needs attention if either of my sons want a chance at it (something about a 4-generation snow-throw appeals to me ).

Fortunately, it was always well maintained and very dependable, so all it requires are new fluids/filters/hoses/belts and a carb rebuild. While I have the original owner's manual (which includes a parts list, nice exploded drawings and instructions - rather forward thinking in 1965) and the original Lawson-Power Products Tecumseh "Snow King" engine Operating and Maintenance Instructions (brochure #181-45, rev. 7-65), there is absolutely no engine HP or model identifying info in either reference.

Of course, the engine stickers are long gone so... how can I determine which engine this is, more importantly what carb it has and, therefore, the carb kit I need to be looking for? Appreciate any help, thanks in advance!

Find the model number on you engine and look closely on the carburetor for a number, usually six digits. With this post your message on the forum link below. A fellow with the forum name “T-man” is the best I have seen on Tecumseh. If anyone can help you he can.

Good luck

Airman -

Thank you for the link. Just to be clear however, there are no model # data plates, stickers or stampings anywhere on the engine that I can find. The only marking on the carb I can see without removing and further cleaning is "Lauson-Power" stamped onto the outside bottom of the float bowl.

Not sure if this is a potential clue, but I should mention that I found a small metal tag in my bag of manuals bearing two lines of letters/numbers. Line 1 is: 5BH-169C and Line 2 is: 0184F.
Thinking this little tag may be related to the engine, I compared it to the model information info in the >>>Please Read Before Posting<<< Sticky, but found no correlation.

I also went to Tecumseh Product's small engine division website www.tecumsehpower.com > Customer Service, Operators Manuals > Basic Service Information > Basic Service and Troubleshooting Information.pdf p.4 "Model Numbering Identification for Tecumseh Power's Full Engine Line" but, again, no usable info for such an old engine.

That is why I posted, hoping someone may be familiar with this old line of snow throws and at least get me pointed in some direction. Thanks again.

The engine may be identified in one of the manuals. The tag came from a carburetor; hopefully the one now installed. The number on the tag is the carburetor part number. This number can be converted to a service carburetor.

Go to the site I referenced earlier and post the information you have. Also, include a photograph or two of the engine.

If you will look in the “Tecumseh Technician’s Handbook 3 - 11 HP 4-Cycle L-Head Engines” Chapter 3 page 10 you will find an illustration showing a cross section view of the style carburetor you have. The illustration shows the “idle and intermediate fuel transfer passage” and the “metering rod or pin” in the passage.

A common problem on carburetors of this type is the metering rod or pin will become corroded or varnished blocking the idle passage. To determine if this is the problem remove the carburetor from the engine and remove the bowl, float and needle. Give the carburetor a shake. If you do not hear/feel a rattle the metering rod or pin is corroded or varnished in place. You will be one extremely lucky and rare person if you can free it up and open the passage. You most likely need a service carburetor and T-man will help you there.

Download manual - Tecumseh Engines: 3 TO 11 HP 4-Cycle L-Head Technician's Handbook from the link below:

One other thought. I suggest you evaluate the engine before sinking any money into it. Perform a leakdown test to determine what shape the engine is in.
