I have an Ariens ST1032 snowblower that I purchased in 1985 or 1986. The engine is a Tecumseh 10HP, but I cannot find anything more specific on the engine itself. The manual that came with it (dated 1/85) is for an HM700, HM800 and HM1000, but none of the pictures match the look of my engine.

The carb on the engine leaks from the bowl. It used to leak, then stopped for years. And now today it is suddenly leaking again profusely despite not being used or moved for weeks. I have tried fixing carbs on lawnmowers in the past and have caused more problems than I solved, so I would like to simply replace the carb this time.

I am attaching a photo of the carb assembly. The only identifying feature I can find is the number "516" imprinted on the body and located (upsidedown) just above the black screw in the center of the picture. I tried searches with that number with no luck. Any ideas what the part # might be for this?

Edit: I just looks again and found the number 51 0121 on the pipe that goes from the carb into the engine (sorry for lack of correct terminology). Did not help with searching, however.

Another edit: The engine has an electric starter on the right side just above the right tire. Could this be covering up the model #, etc??

Is there any other numbers on the sno blower, NOT THE ENGINE, such as

924034-000101
up to
924102-002600

cause then I can cross reference the snow blower with the specific engine model then give you a carb number

 

Thanks so much for the quick reply!

The number is 924073-008401. Thanks!!

 

I have a Craftsman 10hp from about the same year. It is a model 143.786072 which crosses to an HM100-159141M Tecumseh. The carb layout is identical to your photo. The carb number is 632370 and uses kit number 632347.

The model number you posted has three 10hp possibilities:

HMSK100-159024J
HMSK100-159024K
HMSK100-159119M

They all take the same kit and carb number I posted above.

 

Thank you!

I googled the 632370 and the sites selling carbs say it is discontinued and replaced with 632370A. But none of the engine models you listed are listed as compatible with 632370A. Am I out of luck?


Tecumseh 632370A

OEM CARBURETOR
FITS HM100-159080K, HM100-159139M, HM100-159159N, HM100-159065N , HMSK90-156502A, HMSK90-156508B, HM100-159038H, HMSK90-156515C, HMSK100-159243T, HMSK90-156504C, HM100-159038E, HM100-159038E, HM100-159094K, HMSK100-159208T

 

Sears parts look-up also supercedes the 632370 to 632370A and states the following:

This part is an original equipment manufacturer substitution and may be different in appearance but is an authorized substitution.

I am quite sure it will fit and function correctly. After all, there are thousands of those engines out there, the manufacturer couldn't just quit making such a vital part.

 

Looks good! I just ordered one. Thanks again!

 

If you have electric start on yours and the starter button box is mounted on top of the engine you'll need to remove the button box (two small screws) in order to find the model, specification and serial numbers. Find these and I'll confirm the correct carburetor part number. These numbers may have a layer of rust over them and require sanding a bit to reveal them as they are stamped into the blower housing.

 

Thanks for solving that mystery! The number is HM100-159024K which corresponds to what JLOpower posted before, so it looks like I'm on the right track.

 

I installed the new carb yesterday and it started up right away and ran perfectly without any adjustment...and most important of all didn't leak!! Thanks again for all the help!!

 

Just remove carb and go to your local repair shop. HE will get you a repair kit. These guys eat-sleep- and live by knowing parts. In any event when you take off you can do a good rebuild, make sure you replace the neopreme or brass seat that the float valve meets.
If you remove you will most likely see the carb part number anyway/

 

Here's an update from 2014... my son bought an Ariens ST1032 last winter and it would not idle had poor power. ( 10 HP Tecumseh with this I.D : HMSK100-159119T ). I found an Orregon Carb 50-663 replacement at many retailers and bought new to 25.99 WITH free shipping. I had to tap the 8/32 threads in the side above the low speed mixture screw, but other than that it fit perfectly. I had to open the low speed screw about 1/2 turn ( Summer - humid weather) but it purrrrrs!. the rebuild kit for that funky old thing was 13 bucks plus shipping. the orregons range from 25 to 44 so shop around... and I DID take 'before' photos like so many recommended ... and glad I did. Good luck !

 

Thanks for the input and welcome to the forums. You did notice that this thread is eight years old, didn't you?
