Help with MTD tiller machine

[Nandy]

I got me a tiller today for 20 dollars. It runs if you keep pressing the bulb or if you put some starting fluid in the carb. Sounds like a carb setup or clean issue. Anyway, I will need the diagram for the tiller. Also, the cable from the thortle came loose when the previous owner secure it to my trailer. The strap made the cable come loose and I cant figure out where it goes. Anyone with a similar tiller that could tell me where it goes of show me with a photo will be of great help. Also, a place to find the schematics and manuals will be great. These are the photos from the thortle cable and the possible locations where I think it could go.

This is the information in the tiller

Re: Help with MTD tiller machine

Any throttle cable that I have ever seen, on a machine such as this, is clamped close to the end, and the hooked end of the cable fits into a hole on the throttle arm. There are two possible connection points that I could see from your picture #2, but only one combination that seemed to support a clamp point as well.
I have highlighted/edited your picture to show you my best guess.

Re: Help with MTD tiller machine

Agreed with above.

I used to fix these for The Mower Shop here in Medina.

You can also adjust the throttle via that little red slider on the throttle manifold.

You correct, needing to continuously prime machine meant the carb needs cleaned out. Personally I would just drop the carb bowl, knock the crap out of it and re-assemble. Will take all of about 3 minutes and will prolly be all you need to do.

One other thing, just a POI, the second picture is the governor. You don't want to mess with anything on there. they are tuned to work correctly.

Re: Help with MTD tiller machine

Tim Frank, that was one of the locations but I could not find any signs of wearing. However, the owner did told me he was not mechanical inclined so who knows, maybe it came off and he never put it back. There is at least one more bolt missing. I will check today if I can. There are so many numbers in that thing that is hard to get the real mtd number. I found this in the chassis of the tiller:
Model 214-340-000
Serial 1k023k50285
These does seems to be the tiller model and serial. However, I went to MTD site and there is not a match. They also want up to $35 for the manual with the part list!!!!!! Dang, anyone with a part list that can send me will be greatly thanked!

Re: Help with MTD tiller machine

Did try it but the controls are inversed... The photo dont show the air filter and its marks that matcvh the thortle body red slider. The marks in the filter indicate that the red level up is wot (hare) which seems to be right. The marks in the thortle at the handle indicates "turtle" (slow) when the red slider is at the "hare" mark...

Re: Help with MTD tiller machine

Are you sure the throttle lever is original? Is it possible it's a aftermarket one?

Re: Help with MTD tiller machine

It fits perfectly so there is no telling. Looks to me that is aged as everything else. I am going to try to locate a dealer or something unless someone can provide the diagrams or a picture of them. It dont look like it can be flipped either. I know the setting on the thortle body red slider are ok. I ran it feeding gas to it with a concoction I made (I know, I know) and it slowed when I moved it to the slow positon.... Well, have to visit my kids and finish this 10x10 shed before I can put a lot of time in the tiller. Is past garden time anyhow!!! But I rather fix it as quick as I can.
Thanks!!

One thing that puzzles me is this info. Why would a tiller be rated in GPM and PSI?
This may be a "Shadetree-mechanic special" that someone cobbled together from a couple of different machines.

Re: Help with MTD tiller machine

All I wrote are from stickers placed in the machine. If it was assembled in a garage I want that guy working in my boats!!! LOL!
Once it was too late for me to be using my nail gun and table saw I took that carburetor apart to dip in my carb cleaner solution... I have never ever seen a carb so gunk up in my entire life. I have turn a wrench seriously since age 16 or 18. Im telling you, that carb bowl looked like a gel-lo container... Will be in the dip until tomorrow. We shall see. I will clean the gas tank with carb cleaner fluid. I dont think it will hurt the plastic. I will let you all know...

Re: Help with MTD tiller machine

Last night I took the carb assembly out of the thortle body and took it apart. The bowl was full of gelled gasoline. I dip it overnight on a carb cleaning solution can. That took almost all of it. Then this evening I cleaned every component with aerosol carb cleaner and my air compressor. In the process to clean with air I did not thought about the rubber float needle seat. They are generally brass. Well, it went flying in my lawn. I tried to make one up just to try the unit in case anything else was bad I could order it all. I was not able to do it good so I just used a chemical squeezed bottle with some gas in it to fill the bowl until I could see it flow. Once I did I started the motor and I was able to till a grass section of 4x4 using the gas bottle method. Every time it showed sign of being low in gas I will cut the motor, fill the bowl and go at it...
So it seems that all I need is that seat. They are included in most rebuild kits so I would not buy it by itself unless they have it locally. It would be the case of the $1 part but $8 in shipping... Anyway, not in a hurry since I won't use it until october...

Re: Help with MTD tiller machine

That's actually how we used to remove them, give them a blast of air to remove.

A complete carb kit for a tecumseh shou not run you more than$ 5-6. It will also have a new bowl gasket which should be replaced cause they tend to swell once removed.

When you install the new seat, remember the ridges on it go up, or into the carborator. If you put it in backwards it will leak like a sive.

Re: Help with MTD tiller machine

Got the seat and a new needle. The rubber seat has one solid side and the other side has a groove. Now the question is, does the seat goes with the solid part up or with the groove part up?

Re: Help with MTD tiller machine

Check the post i wrote you this morning. Grove goes up and into the carb.

I is leaking big time. I can see the ridges. I tried to remove it with the compressor but it won't. Your positive that is the way it is supposed to be? That I can see the grooves when I look into it? I adjusted the float and no help. Th kit was just the seat and the needle.
Thanks much!

Re: Help with MTD tiller machine

Well, it is installed right. The groove should be seen as you stated. If I flip the carb with the float up it don't seal perfect until I put my finger in the bowl, then it seals great but is like if the float is not floating right. I might change the float as it is $6 and they have it in sock. The needle/seat I got yesterday cost $11. The kit cost 20 + shipping as no one has it in stock and it would about a month...
Anyway to test the float? It was floating in the carb cleaner solution. Maybe I'm somehow putting the needle wrong? I thought it could be put in either way (excess wire to left or right). Any tips appreciated. Never had much problem with a carb, much less how hard is to get help from mtd. I tell you, the unit looks great and worked great when I "jerry rigged" it... I think I'm putting mtd at the end of the least desirable units to buy just for their teck support which is pretty much nothing.
Thanks!

Re: Help with MTD tiller machine

Well, it dont look like it is the float either. I moved the way I had the neddle where the end of tee wire is to he right instead of the left and it seals great. I used water to test the seal and no water sipped. I know water is thicker than gas so who knows, it might still leak. However I found this site:

http://outdoorpowerinfo.com/repairs/tecumseh_series_11.asp

In it there is a picture of the seal. It looks exactly like mine, from the color to having a number in it so my seal was set with the grooves to the inside and the chamfer side to the outside (where you can see it) if it still leaks once I try it again as it is right now I am removing it and putting it the way that site shows. Will keep you updated....

Re: Help with MTD tiller machine

When installed you should no be able to see the grove in the seat. the grove should be facing up, as in facing the top of the carb. If the grove is facing down, or out towards you it will leak like a sive.

Also to check the float the only thing you can do it look for pin holes. If any are found you can give the a quick hit with a propane torch and some solder. Also shake the float. If you have a bad float it will have fuel in it and you will be able to hear it when you give it a shake.

THe wire does not matter which side it come out on. only that it is between the float and the tab.

Make sure the needle is perfectly smooth, ANY tiny bits of gunk on the tip, or ANY pitting will cause it to leak.

Finally if all else checks out you can try to adjust the float slightly. To do this remove the float and bent that little tab slightly away from the float. This will cause slightly more pressure on the needle as the float will be sitting lower in the fuel in the bowl.
