:WRS: . if you want to post pics in your message you need to either upload them to an album on here or photobucket first and then you can post the link to the pic.
do you have a photobucket account or an album on here? the album on here is the quickest.

Yes mike it is a 1974 i bought about ten years ago fully restored and did research on model number when i was buying parts i believe this motor is a tecum just would like to rebuild it completly it has very poor power so i figured i would take apart and rebuild it and the carb i rebuild jet ski motors so thought about rebuilding tractor is it very hard?

sure looks like a teccy to me

ya thats what i thought thanks

Eric,

First, welcome to here, lots of helpful folks hangin' around!

I'm not one of the experts here, so I'm just wondering, before you get too far in your thinking -- is it possible your engine would respond to a thorough tune-up? Or have you been through that already?

Now I don't know, but I been told, if the Horse don't pull, you got to carry the load.

Is the motor worth rebuilding? I believe so or do I find a used tecum, or find a kohler

... I think something broke inside


Other than the poor performance, why do you think this? Did something happen in particular? Are there any unusual noises?

I hope this doesn't sound like a confrontation, I'm just trying to help you focus on identifying the problems and decide what to do next. :)

I'm not clear on something -- does the engine run at all now?

no I don't mide the questions asked great help no it stoped running and I can't seem to get it to run at all. Played with everything. I don't know. A lot about these motors but I do rebuild jet ski motors. I could do a copresion check to starti guess just seemed to to be very poor power even if I adjusted carb to run at a very high iddle

Hmm... Personally, if you haven't heard anything scary with this engine, I would try a thorough tune-up before I started tearing it apart. I don't know much at all about the Tecumsehs, so somebody else will have to help you with the specifics. But an engine is an engine, the principles are the same, and if you have experience with jet ski engines you should be able to handle it.

I would start with the basics -- oil level, spark plug, air filter, check for fuel/spark/compression, all the usual stuff. If those check out OK, it might be time for a carburetor rebuild (and maybe some other fuel system work as well).

There's a Tecumseh service manual that might cover your model (HH120?), it's in the Files section of the forum:
http://www.wheelhors...cians-handbook/

Check it out and start exploring, and let us know what you find. :popcorn:

I know exactly what went wrong! It died....lol

techs are known for Carb, fuel pump and ignition issues. Start with those, like Tuna said the basics, fuel & fire first, then timing.
