- lets talk about the differences, similarities, and overall impression of tecumseh carburetors old style adjustable vs the new style non-adjustable.
These are the type of carburetors you will find on snowblower engines. - ยานยนต์และพาหนะ
Replace the carb bowl with the one off your adjustable carb. It'll give
you the dump valve you desire. Be sure to put the solid bowl nut back in not the adjustable one. Tom
Enjoyed your video. In the past several years I have bought 4 used snowblowers that have needed some TLC. The 3rd one was a craps man 8.5/26. Besides the auger problem, I had a issue with the carb having the evaporated gas residue. Took it apart and found that the float needle was sticking in the nylon seal seat. Unfortunately with my deep cleaning, I compromised the seat and I bought the Amazon Hooli carb which costs less than the rebuid kit as well as the tools required to replace the parts/seals. Now I'm working on #4, a Craftsman 9/28 and have I fixed the siezed auger blades on the shaft and installed bailer belt on the impeller blades that is corded material and cost only $7 for a 7" x 12" piece. Now moving on to my craftsman 9/28, 12" impeller that I will clean the carb and possibly R&R it with the Amazon carb if necessary if I can't get it cleaned up. I also make blower skid plate modifications on my blowers by replacing them with roller blade wheels that you can buy for cheap at garage sales. No skid plate adjustments or scraper blade replacement/adjustment, required!
One really good thing about the adjustable carburetors is that elevation changes do affect your engine and if that happens all you have to do is adjust it.
Yes at 6000' elevation I have to run my 9HP tecumseh with original fixed mixture with the ckoke on the first notch or so
From Dillion Colorado (9100 ft) to Parker (5800) Colorado I have to do the same thing on my 8hp..altitude does make a difference.
I have a Troy-Bilt Horse rear tine tiller that was purchased the day I was born by my late grandfather. Ants destroyed the fuel system. Just had to scrap an old snowblower, scored an identical motor in decent shape with 115v start option. Wish me luck. I love being able to see a teardown or overhaul before I try it. Results in fewer extra fasteners. 👍
I'm slightly struggling identifying the carb off my 10HP Tecumseh flathead Snow King motor on my old Troy-Bilt snowblower. Your vid is absolutely brilliant and showed me everything I wanted and needed. Well done and enjoyed the Scent of a Woman blast. LOL. Thanks very much. Regards, John from southern PA
Good video and it's nice you try to be fair and unbiased. As far as I can see, if a carb works ok, what's the problem whether it's adjustable or non-adjustable? You're good to go either way so no issues. Others have made the good point if you live at altitude, adjustable is a good feature. Most Americans live under 2000 feet so the non-adjustable would likely work fine for most of us.
I am still running a 1972 Ariens 24" SnoThro purchsaed new with 7hp Tecumseh and this style carb. I live in Western NY in the lake effect area so this machine has had a workout. The dump valve started leaking and I replaced the bowl with the new style without dump valve. It was about 80% cheaper than the still available type with dump valve so cuz I'm frugal, I went the cheaper route knowing the engine would run the same.
I set the original bowl aside thinking I might try to replace the tiny leaking "O" ring some rainy day. Recently I was able to do that very tedious and fussy job successfully. I used tweezers, a little pick tool and a couple jewelers screwdrivers to keep the valve pried open. It was not easy and taxed my patience but I enjoyed proving it CAN be done if you have the will. You almost need three or four hands so don't try this when you are tired or in any kind of a hurry. I reinstalled the repaired bowl and it's working fine. I like being able to dump the fuel before off-season storage. First I run the engine out of gas after siphoning the tank empty while the machine is tilted to get the most fuel out. I also put a tiny amount of Stabil in the tank before starting the storage process. Might be overkill but it works for me. Have only taken carb apart for cleaning once in the 51 years I've had the machine. They don't make 'em like they used to ;-)
I agree. It's like the old '97 Ranger I had, probably the last truck on earth with a manual transmission. I don't want no machine telling me what gear to be in or what the mixture should be. Control freak I am. A dozen years ago I actually worked at Ariens machining parts. Sucky 3rd shift job and by then they were using Briggs motors. At least now I have an old '80s Snow King and once I figured out what those adjustments did, I never had a problem. Great video THANKS!
I just bought a $14 carburetor off of Slammazon with the accessories and it’s adjustable like your old one!
I do like to have an adjustable carburetor. Though I can say that none adjustable carburetors do have their merit. There is also a reason that I prefer Edelbrock to Holly when it comes to a carburetor for a vehicle engine both are adjustable but tuning a holly is some kind of witchcraft that I don't know nothing about or very little at least. Now that I've written you a book I think both ways have their own merit. Have a good day my friend!
Great video. I’m looking for a replacement carb for my Simplicity Snow King HSK70-130292T(H) late 1990s snowblower which I believe has the Tecumseh 632371A carb. I checked Amazon and saw a Hooai carb replacement for the 632371A but the description says “Not Compatible with 10% Ethanol Gas.” I guess I can’t use this. Do you have any suggestions? Thanks so much.
I am suffering the same dilemma and having a hard time making the switch. For $14.00 I think I will try it. I also see that you too are a Rock Auto fan. Thanks for sharing.
I have been using them Amazon carbs on all my small engines for years. Not a single one has been bad. Mind you this covers back pack 2 stroke blowers, line trimmers, outboards and lawnmowers. For the price its a no brainer. And in almost every case it leaves me with an extra carb for parts if im in a pinch and need to help someone out rite away.
thanks for the advice
Do you have an idea who to get in contact with on how to get me a carb for an 70s snowblower? I do not have a parts manual. Is a Craftsman. Thanks.
Thanks for tip got 15 hp b&s over fueling got to get one
I was hoping to gain some insight here - although I've reworked Tecumseh carbs for a long while.
As soon as you stated that Ethanol BREAKS DOWN INTO WATER (an absolutely 100% false statement) I chose to down thumb and leave this parting shot.
Ethanol Alcohol is mixed with gasoline because it makes cheap gasoline even cheaper. The Ethanol mixes VERY easily with water and after the heating of the day (expanding the air in the fuel tank) the cooler temperatures of night cool that same air and through shrinking draws outside air into the tank. That outside air contains some water vapor which condenses on the inside walls of the Carb. Liquid water particles contact that Gasoline hosted Ethanol Alcohol which VERY actively acquires the water, absorbing it into the alcohol.
THAT is how liquid water and alcohol end up together inside the tank. Alcohol prefers water to gasoline.
Concurrent air exchanges provide Oxygen which results in corrosion inside the tank (and carb bowl).
Good luck pushing your own thoughts here.
I have never worked with an adjustable small engine carb. I have bought several cheap Chineseium carbs from Amazon and they worked great. Maybe an adjustable one would work better at higher altitudes where the air is thin but I haven't noticed any issues. I live at 4500 ft
I just put a Sino carb on my Tecumseh 10hp and it runs rich. Starts easy but burning rich. Afterfiring and foaling the plug. The original factory was none adjustable but gunked up. Ethanol thank you.
Going to replace with a Sino adjustable probably. Looking for replacement now.
Nice video. Thanks. I was wondering if you know the name of a Tecumseh carb pieace. I have an older 2 cycle 1 stage Craftsman, and the carb has this gold color cup in front of the carb covering the butter fly. I need one and I don't know what it's called to look it up. It doesn't show on the parts diagram. Thanks.
I like adjustable carburetors. I believe it was about 1993 that Tecumseh went to non adjustable on the 8 HP Snow King. Back date to an older carb part # 632334A. You can get Chinese versions of it too
How do you change the chock set up
I have a new one of these but it has the old adjustable bottom jet. I think you can still get them.
I have a 2003 ariens blower with the Hssk 5 hp. I bought the king brand carburetor which has no adjustments. But either does the original carb. Ended up putting the original on but the fumes are bad. I know my spring adjustments are messed up as the governor doesn't give me enough rpm, but it gets the job done. Maybe I'll try the Chinese carb again. What about but a carb from a small engine dealer for around $70?
EPA forces them to run too lean. The newer ones that are not adjustable will surge eventually. Sometimes they don't run well when new.
I have a 10 HP Ariens snowblower with the original carb. Would the new carb work on it ? It is a Tecumseh engine
Hello. Didnt they stop using two bolt adjusent because of some co2 emision or something? I have nikky carb with no adjustment in my 2008 murray. On idle it does not sound that great but under load sounds great.
On my trimmer i have only 1 adjustable bolt and it is a bit limmiting to set up how I want it... but I use what I have
I just finished the video and you explained it well. Good video sir
That could be. They were tired of guys tuning them to run rich or something I guess
I need a link to that sweatshirt ASAP, looks awesome
I like both
I bought one and it wouldn't give me any power, then I bought an adjustable one and it works great. 1995 5 hp Tecumseh
I took you up on your recommendation and bought one of these carbs... My snowblower now has two speeds, racing and off. If this is non-adjustable, what's the answer? I made sure the linkage was in the exact hole as the old one, but that said these replacements aren't 100 identical... Thanks for any suggestions that might help.
you still have an idle speed screw on the throttle. Just adjust it there. It's not an air fuel adjustment just speed.
How do you adjust the new type of carburators???
Those Chinese carbs do work. However I've had at least 2 leak right out of the box. I finally found out that during shipping and handling the needle valve becomes dislodged.. So the fuel just keeps flowing. You even have to be careful installing the carb and keep it as horizontal as possible when installing it. After that they work just fine and you can't beat the price.
I had the same problem…brand new carburetor leaking gas profusely. I removed the bowl and worked the float and needle valve up and down and it stopped leaking, but the engine won’t run without partial choke, but no adjustments can be done.
🤣 Love the Al Pacino reference. Perfect 👍👍
Love the hoodie where did it come from? Always have to show off the love of the 4.0. If you made it then I would love to see you sell them, there is no 4.0 appeal on the market.
My bro in winterpeg put a chinese carb on his blower too. Says it pops a bit at mid range but is good at idle and wot. Now that winterpeg is almost the tropics they dont have to blow snow every day like when i lived there many moons ago.
They have an adjustable chinese carb on Amazon
I am curious to learn how the old style defeated you though because you are good with a carburetor my man
Yes, he did say he was going to get back to that.
I'm pretty sure he was gonna say that the old carb defeated him, because after thoroughly disassembling, sonic cleaning and completely going through it, it still didn't function correctly. I've had a few like that myself. I bought a new carb (whether adjustable or solid), installed it, and it ran beautifully.
3:50: "irrational desire to clean carbs all day" lol - you are not alone bud!
Can you replace a 631499 carb for a V70 Tecumseh
@DougvCarburetor, What exit?
I like the content. But I would prefer the old adjustable carb . But also I would try and clean/rebuild it first b4 I would I buy a knock off ... but I have bought that hooai b4 .some times it worked and sometimes it didn't.
My snow blower had the one with no adjustment screws on it
The only problem I’ve had with the china carbs is the float not seating well.
PART NUMBER FOR THIS FROM AMAZON?? PLEASE HAVE A 93 CANADIANA TRACK STYLE-LOVE IT!!
I picked up a old Sears alternator generator, think made by David Bradley,replaced fuel lines, added filter, no rust in tank, mabe made in late 60s. It ran for about 30 minutes like a top, I tried to adjust carb it cut off, and now won't start lol, leaking a little gas from carb. No labels on engine, I think is a 6hp tecumseh. Guess I will try a new carb.
Once my Ariens St874 needs a new carburetor or once mine starts leaking I'll probably get a Amazon special for it and keep the old one and rebuild it for s spare. I have thought it would be a awesome idea to get a fuel injected 8hp to replace it if they even make them it would be a cool idea I think. But Iowa like you we don't get to use them all the time which sucks.
Only thing I don't like is you have to trim the lock washer on one side to get the nut to fit.
... some work for the country, sum for the ring. Others for the planet a prince for a king. Most work for themselves till death due us pass. I worked out how you did it and why...
Adjustable jet makes it easier when dealing with elevation.
My 2003 Troy 7524 snowblower came with a non adjustable carb.
How do I order that new carb you got ???
I put Chinese carb on my MTD snow blower 10.5hp Tecumseh engine so far so good I can't adjust the old carb life of me
I’d rather use a adjustable, u can dial it in way closer. Every engine is gonna be a bit different. And your elevation it gonna impact your tune also. Like in the mouth and may run great bit hot see level gonna run like crap.
Just be careful some of the new carbs are missing the Welch plug
I have an 8hp tecumseh on a Coleman 5000 watt generator. Carb looks nothing like the 80’s carb. Bought new back in oh around 2008
Rebuilt once. Ran good for maybe 6 months. Then back to oscelating and now back fires. Time for more carb? I think so
You gotta get that money and put links in the description I woulda clicked
non adjustment carbs became the norm due to the EPA
We have polite snow were I grew up, went to school , the snow may have lightly dusted everything , came in at night dusted all house b
Let's talk about that hoodie ?
It is my own design.. you a Jeep fan?
@@DougvCarburetor all I drive or own is jeeps with 4.0s. Except my 1965 cj5

@@DEInTheGarage i watch every time you upload a video and ive meet up the Dan H once with some parts
Yeah, I'd want at least one. I know a buddy that would need one as well. Would like a darker color, light color shirts don't stand a chance with me. I look like I fell in the grease trap by 10 AM. I don't own any 'nice' clothes, just 'new' work clothes that aren't completely fucked yet.
I always order the adjustable one they make them thare yously on 10 are 11 hp engines
That fuel line is not long enough and the diameter is too large to squeeze through the slot it has to fit for a Tecumseh HM series. good luck that the valve does not leak or jam in position. The filters are not needed as the gas tank has a screen.
Adjustable, plus if it's not I will convert it so it is.
.As gas goes The old gas was the best. With today's low efficient gas, as soon as it gets air water forms, hence the air tight gas can. and pressurized systems in cars. and never let it sit in any small engine tank for long period..... , it rots hoses and turns into something else.
Just ordered my commie Tecumseh carb to replace the OEM one on an old troy built horse tiller I just snagged for 100 bucks. I hated doing it but you are correct. I have installed tons of these clones and never had a single issue. And they cost less than even a rebuild kit at this point. Just not worth buying the original for 99.99% of people.
Do you have the Amazon link for this
@@blackjoebufa it's been a while but I should be able to find it in my order history. Give me a couple of hours and I'll track it down
non adjustable carbs were for emissions control
I think your theory is off they need adjustment for temperature altitude and fuel quality the non adjustable run like ass and need the jets drilled at low altitude and low temperature if it surges open the jet
By that logic, all new machines with non adjustable carbs wouldn’t run at altitude or when it is too cold. I had the same thought originally, but the reality is that fuel refinement has gotten consistent enough that it will operate properly in 99% of conditions.
just received a non adjustable carb just like OE put it on fuel leaking out of bowl tightened fuel bolt/jet still leaking removed carb adjusted float engine wouldnt run right readjusted float still wont run right and fuel still leaking from bolt smfh, got it running but surging and missing, new fuel and plug misses on high speed surges on low speed or idle this thing ran perfect 2 years ago then went into storage thats all I am baffeled, original carb would only run on half choke, yes low speed circuit, cleaned carb as best I could not a difference that is the reason for new carb, on 6 horse ohv Tecumseh what is going on?
I like set and forget but like to beable to set
1 last thing. It's a 5 hp Tecumseh engine
I'll take the old adjustable carb over the new crap any day.
Gg lots of help. Gonna slamazon and return if I can stop this tiller h30 engine from leaking 92-3’ maybe late 80s 4 stroke
Edit: this shit is so funny 😂😂
The EPA made them do away with the mixture adjustment they dont want people adjusting their own carbs
Doug v Carburetor I like Tecumseh carburetor with adjustment myself better
I do not blame you! Just something about having the option of you need it
I also have my own small engine repair and lawn care business
Tecumseh New Holstein Wisconsin U.S.A
I built (wrote) the program for the cam and crankshaft grinders on site. 1994, 93 94. U.S.A. I use both but prefer, the original, I save the original, can rebuild it and shelve it for the next machine, or rebuild jit.
Thanks to everyone.
Keep wrench'n.
Keep Truck'n
I've had exactly 2 Chinese Rainforest website carbs that have ever functioned properly. They were 2 stroke carbs. I bought a Jungle website carb for my Honda 4 stroke lawnmower...it ran worse than the original carb. I ended up rebuilding the original carb and threw the Amazon People's Republic carb away. They just don't have the quality control or correct specs/jet sizing in those cheap things. Absolute trash.
I remove all Ethanol from my gasoline that goes into my small equipment .
Watch AVE much?
Just goes to show how cheap these carbs can be built for.. call it Chinese or what. Ever. Do the 14 dollar carbs run?? If so I guess the only cheap is the price...
Put a knock off Mikuni
If it works great who cares.
$14 dollars in 2021-2022? Now, this kit is $28.80 + $14.20 shipping. I don't want to make a 7 year old kid loose his chineesium job. 8 year old took his place. Why? He's got shoes and has been casting metal for 14 months. No substitute for Experience & shoes around hot metal.
Bought two for an engine that ran fine until sitting, both never ran worth a crap I had to clean the original one to get it running again
"This is what they're putting on new units."
Lol where are these new Tecumseh products you speak of?
i replaced my snowblower carb and i found it dont have regulators screws ...i went to amazon and buy for 18$ and they have the 2 options for the same price and i get the one with the regulators thinking its the new upgrade....a lot better with regulators and that was the reason i replaced ,,,i couldnt regulate the old one......but you are upside down ha ha
