Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Well, I had the seed planted in my brain by Richie installing an adjustable carburator on his machine....It didn't take too long for it to take root and start me thinking.  I purchased an adjustable carburator on ebay (rebuilt) for $58.  This weekend I installed it and now have it tweeked to run well.  No problem installing it, only had to make some adjustment to the govenor and the high speed limit screw to get the rpm's below 3700.  I had a little problem getting the low speed mixture screw to do anything..  After futzing around I finally got it to do its thing and got it adjusted to perfection.  The tec engine generally does run smoother and appears to have some additional umph.  I got to use it twice today to continue "testing" it. (By the way I now have 11hrs of use since January).  All seems to be well.  Sometimes I get the occasional "pop" or hick-up when idling at full throttle but it does not seem to hinder the abilities of this engine.  All in All I am 95% sure that this was a good move to make.  My EPA carb did not display the problems with surging or power...just made the engine shake like hell!

So far the redesigned chain tensioner is working as it should with no problems...I will keep my fingers crossed

Hi Robert,

Sounds great.  Did you notice how much easier it was to warm up?  Originally, I had to fuss with the choke more than I felt I should have with the EPA carb.  Good move getting the Sundec, it really takes all the guess work out of it when it comes to fine tuning

Now I am wanting one.   But still am unsure if it will void the warranty.  I just don't have the umph to do it.  How much did it cost you guys alltogether?  Maybe the dealer would buy the used one.   

Hi Guys_

AJACE-The part #  for the carb is 632334A. The parts places are going to ask you for the spec # off your engine which then will not cross match.

Use this # off of my pre EPA engine that came stock with the adjustable carb. It is an 8HP L-Head Tecumseh.

HMSK80

Spec #14 5555 OUH

Many of the parts places on the net have the carb. About $70 to $80$.You might want to order repair kit#632347 while you are at it.I like to have the "just in case " rebuild kit cose at hand. Especially for a carb that isn't being used anymore by the manufacturer.

Marc

Wow, I wish I was that good at this OPE stuff.........I'm proud of myself when I change the oil........

maybe someday I'll get there.

Ajace...you wanna give the dealer a heart attack or something?
If the mechanic sees a non-compliant carb on a new machine he will more than likely drop his tools and run out of the shop screaming, "I didnt do it...I didnt do it....I swear by all things holy....I didnt do it."
The epa carries on with an old Muslim tradition of "hand removal" if we get caught even standing next too a machine that isnt compliant.
Heck.....I had too bury my "tiny drill set" in a coffee can for fear that the epa might make a spot inspection.

Marc, thanks again for posting that important SPEC number

Fred,

Nice website link.  I added it to my OPE links for furture reference. 

I was looking at the Kohler engines.  I loved how they give the consumer all the information they require about the product.  Complete engines ratings and specs.  Even an easy to see and understand HP disclaimer.  Then you go to the Tecumseh engine section to look at specs and they list nothing.  I've seen this happen on many other sites.  It has to be that Tecumseh doesn't supply them, no other explaination makes sense for this.  The Kohlers look like great engines.  Great information that can come in handy if repower is needed on a piece of OPE. 

MM14, thanks for that number.  Buttlint scared me with what he said.  I'll didn't really have that umph to do it anyway like I said.  The engine sure does vibrate a bit though when at idle.   I do like Kohler engines but I heard after the have been used a while they seem to have valve/piston problems?  I know that all engines need overhauled, but something seemed to stick out about Kohlers.  I guess it was lack of lube inside.  That hour meter/tachmeter I have is really great.

AJ,

Good move on the tach/hour meter   Hey, that photo below your post isn't really you, is it??

I really really wish that it was.  It's the Ariens company testing their equipment.

AJace wrote:

Hi AJ,

That really is an incredible photo, must be their 13 Hp model.  Maybe Ariens should consider marketing them as snowblower/tunnel boring machines. 

It kinda looks like my 926 DLE or the 11528 series. 

Hi AJ-

Lint was only "funnin" you!

 You got to do that carb!!

 Its' a librerating experience!!!

Kind of like an EPA Boston Tea Party!!!!

Changing to an adjustable jet carb is Patriotic

Marc  

I'll wait until after my warranty expires, then if I have any gusto I'll do it. 

AJace

You need to live on the edge like us.....nothing will ever happen to your machine that would require warranty work!!!  That is one reason that I bought a separate carburator so that if I ever did have a problem, 45 minutes of time and then I am back to stock.

 BBWB,

 Just make sure you clean the carb you took off throughly with carb cleaner.

You do not want to Gum Up the works!

                                               IMHO   Fred   

Yep, all cleaned up and ready for bed

I used to work in an autoparts store about 22yrs ago, and they used to sell "test pipes" that could be install in place of the converter to "test" if it was bad.  I don't know if they still make such a thing.

bbwb,

I'm down here is Gods country where most farmers and outdoorsmen cut them off anyway. I went from using the original one to putting on Hi-performance cat's to just having them cut them off and put a piece of exhaust pipe in it's place, in other words no cat at all.

I lost a new Chevy Silverado 1/2 ton 4X4 Ext cab with a custom fiberglass camper shell to fire one time because of the catalytic converter starting a fire under the truck while it was parked, actually buried in mud/clay. The hot cat started the pasture on fire under the truck and I couldn't get the truck out, watched it burn.

I swore that day I would never run one again if I could by bypass it. I still keep them though just in case.

(we don't have state inspections)

Robert,

Since you have the new carburetor nicely tuned, it's a good idea to check the color of the plug once in a while.  I was able to tune my carburetor so the plug electrode has a nice tan color to it, which is just the way I like it.  It used to be much lighter in color than that with the other carb.   

I wish I had my old EHT gauge handy, I'd love to know how much hotter, if at all, it ran with that lean carb it had.  I recall the range was, 375-425 degrees.  The EPA jetting is something like a #167.  I'd have to check my book, but I always thought jetting with a number that high was for altitude, but I'd have to say it doesn't matter since you'd have to lean out anyway at altitude.  Anyway, the spark plug tells the whole story. 

Hi Richie:

Yeah, I will check the plug to check the color.  Nothing beats the tan color in my book as well.  I am trying to think when I looked at it last .  I also have to believe that a smooth running engine is more efficient.  We are to get some snow on Sunday, 4"plus, so another workout with the Ariens is in order. 

The more I think about it the more that I am impressed with the throwing potential of my modified blower.  I feel so much better knowing that the drive chain will not leave me standed (locked up) at the end of the driveway.  I only wish that the drive components from the factory did not have the appearance of being designed by accountants!

By the way...you claim that Marshall started all this....think that he will chip in on the $ for the mods?

Robert

Yeah, that drive modification you made was real impressive.  If I ever have a problem with my brand snowblower, I'm coming to you for help   As for Marshall, I'm actually grateful to him for putting a certain bug in my ear.  If not for him, I never would have started doing all that research on the HP/torque rankings of engines, nor would I have started on my quest to replace my carburetor.  I won't be asking him to chip in for my carburetor  Make sure you let us know how everything works on Sunday.

I thought that BBWB had a Toro. 
Marshall, that was auful, and have heard about what can happen when parking my truck on grass if the hot parts get too close.  I think that state inspections are the best thing possible because you need to be safe.  Paying for them is another thing. 

Hi Folks,

I stumbled across your group while doing a search for Tecumseh snowblowers.  I was hoping to find an online troublshooting manual for my machine.  The last time I used it ( that two feet we got here in the NorthEast ) it began to lose power to the point of almost stalling.   This was after a couple of hours.  I had to play with the choke to keep it running, let it idle for a bit then continue.  Ran OK for a while and then the same thing would happen.

So I started it up this afternoon after checking out the forecast and the same thing happened right away...only it kept stalling.  I assumed ( very bad move ) that the idle could be adjusted and went and turned the screw on the carb.  Now it won't start at all

Have I messed things up big time or is there hope?

Pete

Hello Pete and welcome to our forum.

Please provide us with the year, make, and engine size that you have.  Being able to use it during that last big storm, it almost makes me think it was overheating.  As for the screw you turned, maybe you closed off the low idle mixture screw.  Please give more details.  Also, it may be better to create a new post on the main page of this forum.  This way you'll get the full benefit from all the talent Abby's has to offer. 

Welcome Pete,

Tecumseh manual
I don't know if it is supposed to be free. But it is the 3 to 11 HP 4 cycle manual in PDF.

Real carb help will come from those that know. You will need to post model numbers and such. Might as well do that a while.

You could start a new thread if you chose.

Hi Pete & Welcome

On your blower, try turning the same screw back out and see if you get back to square one.  From there, you might be able to slightly turn the screw to get it to run right.  Also, make sure that you have new gas in the tank...old gas for some reason does not like to burn.

Richie, Thanks for the compliment....I am not sure that I did anything that someone else might not have figured out.

The weatherman tells me that I might get 1-3" tonight in addition to the Sunday snow event.  Man I love this!!!!

I don't even recall changing the plug on the blower yet...might still be factory issue.  I do have a new plug waiting in the wings.
