Need help identifying an OEM tecumseh lawnmower carb that came off a snowblower.

I'm trying to identify a tecumseh lawnmower carb that came off a snowblower. I have scoured the internet and have had zero luck... The bowl nut is part# 632385. All I'm seeing is the bowl nut is used on CCR Toro's. NOTHING with a push to prime. Any help would be highly appreciated.

Look for the manufacturing number and then post it.


But I think is a Dellorto carburetor which I have no info on.

Looks to me like a Tecumseh #640278, but I’m running into a memory problem. Looking at your pic I don’t think that that carb came on a snowblower engine, as it is most commonly used on mower engines. Are you sure that it is the original carb? Do you have any numbers off the engine ID tag?

I know this is a mower carb. 640278 is not the correct carb. carb 640278 uses 640050 as the bowl nut. no bueno.

Now I’m totally confused as to what you are looking for. I identified the carb in your pictures. Are you trying to find a lawnmower carb which uses specific snowblower carb bowl nut?

No.. I'm trying to identify the carberator part# man. That carb you listed it similar but it has a manual choke lever to connect a linkage which mine doesn't have.

Find me a tecumseh push to prime carb that takes the bowl nut with the huge main jet. It's a fixed jet (non adjustable) so I'm thinking it came off a machine from the early 2000's or later. possibly a 2 cycle engine.

Good luck in your search. Finding the specific carb which uses a specific main jet is not easy. Just as your carb came from a mower, I’m willing to bet that the jet came from a blower. Probably a “fix it job” done by a “DIY GUY” from his “ I’ve got something that will work” scrap box. If you find what you are looking for, I recommend you also go buy yourself a lottery ticket.

Done a little more digging here. It seems to a series 6 4/2 cycle carburetor. Try looking at the 632466 which was replaced by the 632795A.

Star, I found that one also, but the OP has stated more than once he wants a fix-jet non adjustable carb.
