According to the parts list the carb is a 632351. This engine is on a 30 year old generator which I bought new, it burns no oil and other than carb cleaning it has been flawless. Now the choke and spring assembly is broken and has to be held in place with a stiff wire once it is warmed up.

This carb seems to be unique to particular HM80 models and not available even on Ebay except a new Tecumseh at close to $100 while a bunch of import replacements are in the $15-35 range for other Tecumseh models in the HM-80-100 family. At 77 Im on a fixed income and this winter has already been rough on finances.

My questions:

Can I use one that has no needle jet adjustment? Will my bowl and a new needle/seat kit work....or am I fighting a metric battle?

Can I use one that has the gas inlet at a right angle by unscrewing and using a straight one? Cant tell from photos if they unscrew. Otherwise I'll run a new gas hose.

What about ones that have 1-2 extra (vacuum?)ports? Can these just be blocked/plugged?

Does anybody have a bolt on replacement, original, rebuilt, etc I can afford?

Thanks for any help,
John

I see a used one on ebay for $16.00 obo
and several new ones for $12.00 to $30.00

Or, am I missing something?
Good luck!

Ive already seen those and they prompted my questions above. Do you have specific answers?

I ordered one these cheapy carburetors for my HM 100 Tecumseh engine about a year ago, $15.00 or so, worked great 1st pull started right up, only had to adjust the idle speed screw, which was the ONLY screw on the carb, just make damn sure you check the pics of the linkage arms, to be sure you are ordering the right carb, the links below show various Tecumseh carbs for an HM 80,.. but I did NOT see your number, as long as its for an HM 80 and the linkage is the same, for that price, go for it ! beats $80.00 + for a new one ......

This one has the straight in hose connection: https://www.ebay.com/itm/Carburetor...022873&hash=item1c926adba4:g:OoYAAOSwL4BZr-QG

And appears to be the same as this used one: https://www.ebay.com/itm/Tecumseh-C...863514?hash=item2f1261d1da:g:qgUAAOSwk1haIYfw

But, without seeing pictures if yours, it impossible for me to tell.

AND ....... THIS, is the one I bought last year, guess we gave ya something to look at

All those have various differences from mine and excuse my mangling some terms:
Also I cant post links until I increase my post count, maybe these will get thru.

- no main jet adjustment
- extra ports for what? Fuel, air??
- part that the governor rod goes into has stop on wrong side or no holes for the rod

Looks real rough and looks like a hole in it

Similar reasons to the above and I dont know enough about what parts I can swap, if anything, from the USA original and the Chinese offerings.

I managed to get thru the last storm without power for 4 days and will try to take a few pics soon once the WX reports look good for awhile so I can pull the carb.

John, when you get your carb off, check to see if it looks close to this one, this has the original p/n to your carb, the fuel inlet port is straight-in, the other "barbed black port" near the the inlet side looks to be a "breather-line connection" ( can be blocked if not needed) the only other concern is the linkage arm, I too live on a fixed income, so I know your concerns about money, but for $11.00 with FREE shipping ... I wouldn't hesitate, it's your call ! keep us informed ....... Boobala

BUT BUT that one has no main jet adjustment which is critical especially for a generator.

I suspect that extra port is for a primer bulb which could be useful at super cold temps.

What is with those Chinese "Tecumseh" carbs with two bowl adjustments??

John

WELL ...... MY BAD !!

Just noticed I'm trying to answer 2 different posts on 1 thread ! ..:confused2:..:thumbdown:

I have,.......... Gearhead101 from New Hampshire has a Generator post signed as (John)

AND I have.................... Geoff813 from New Hampshire has a Craftsman post ALSO signed as (John)

SO after spending much time, researching all the model and part numbers, I'm going to give you ( whoever the #@%$#@% you are,
SOME of the info I dug up, and YOU... can hash through all the schitt and find it yourself !

https://www.partstree.com/parts/tecumseh/engines-horizontal-4-cycle-engine/hm80-155288j/

Well, no need to get all upset and I very much appreciate all your research. If I cant make something out of all that help I better give up.

The reason for the two ID's is that I forgot about Gearhead101, which is me, and the other is my sons, who is also a gearhead but mostly on vehicles. I go back to building and racing flathead Ford V8's.

Off to more reading those links.

So much easier to PULL a chain, than to try PUSHING one !

I spent several hours researching info for someone, then come to find out I'm being played by someone pullin on MY chain (or so I thought) had he used his ORIGINAL posting name, things would have been different, damn right I was totally pissed ! so I went and deleted all the other schitt I was going to send him, I'm NOT going to go through all that digging again, the damn carb will work or it won't, for $11.00 he shoulda JUMPED on it, NO longer my problem, I don't like people jumping in on other folks threads and then you're trying to find answers to two different sets of questions, yet similar to each other, he should have stated in his post he was the same guy, earlier, Anyway I think he has enough info that between him AND his son they can handle it from here.
