HELP! Tillotson carburetor

[ErnieG]

I have this Tillotson carburetor from my Jiffy model 76 White Lightning ice auger and I'm trying to find a rebuild kit for it but I don't know the exact model carb it is .
I think it's a HU model but don't know for sure ... anyone recognize it or know what rebuild kit will work ?
The only marking I can find are ...
100B125
HU
91
71
These are all stamped on the carb body
Thanks for the help !

What engine is on your Jiffy? Most had Tecumseh engines and the carbs are identified with the engine model/serial numbers.

Edit:
Looks like these may have a Jiffy branded engine.
This should be interesting.

Look at this link and compare your gaskets & diaphragms.

My notes say the Zama RB-1 and GND-1 are the same as the Tillotson HU.

Its a Tecumseh tc300 model engine from the stamping on the engine itself .

OK. What numbers/letters come next.
Should be 31xxx

[GMB74]

Carburetor: Tecumseh part number 632901A (for reference)
Diaphragm/gasket set 632934
Rebuild kit 632933

Keep in mind Tecumseh has been out of business for quite a few years now.
Most responses for these part numbers are going to be Chinese-made copies.
They may or may not work ok.
If you want OEM/NOS parts read the ad carefully to be sure of what you are buying.

So it looks like there are a few Tillotson brand carb kits but what's the difference between these two ?

RK21-HU and RK14-HU

 

[GMB74]

RK21-HU appears to have a shorter inlet needle?

 

[GMB74]

RK21-HU claims to cross to 632933:

The ad lists your TC300 engine and HU-100B carb.
Note that this is an aftermarket kit, not OEM
