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 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?

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?

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.
