My son Parker and I have finally started on his Cub 123 that we bought back in March (Here's the link http://gardentractor...bolen-and-plow/).  The first thing we did was install the starter/generator. 

20170626_201808.jpg 20170626_201824.jpg

Next was the carb..  He took it off but I took it apart and showed him it worked.  I was surprised how clean it was on the inside.  I sprayed it down with carb cleaner, blew it out with compressed air, and reassembled it.  It's good to go!

Third was the voltage regulator.  The old one did not have a cover so I'm replacing it with one from a Cub 122 parts tractor.  I got some questions about these regulators before I can reinstall the new used one.  I will probably start a new thread for that once I do some research.

New used

The only other thing that needs to be done is order a new ignition switch (old one was missing) and pick-up a new battery.  More to come once we get the parts.  Hopefully everything works as it should.  If all goes well I will install one of the mowing decks that I have laying around and let him start mowing our 2 acres of grass.

If the regulator is the points type, make sure the relays (mechanicals) are free, and clean, and make sure the points are clean.

These are easily adjusted, plenty of GREAT info in the manuals section of the site.

Last, but not least, looks like the best young helper I have seen in years...teach that youngster everything you know. That young man will be a millionaire, all young folks wanna do is play VID Games, not learn mechanic work, plus it's good qualty time!!!!!!!!!!!

Thank you for sharing;)

The quote feature isn't working right now nor is the cut and paste so I'll have to do this the old fashion way.

 

Stiemmy- Thanks for the information.  I looked up the service manual for the 123 and their is lots of information about how these regulators work.

My sons is a good helper even if his attention span is sometimes short but that's to be expected for a 11 year old. :D

Kenny- It's good to be working on it!  Sports, funerals, vacation, other work have kept us from working on it.  Schools out so now is our time to get it done so we can take it to a tractor show in August.

That's how I learned a patient father . Good luck to you and your son with
this project.
It's good to see him interested. So many younger kids have no interest
in anything if it's not a computer or television
Pop and I both had street rods together and now both do the LGT hobby together and I'm in my
fifties. It's a lasting bond .
Very nice!!!!

Thanks Kevin!  I'm trying to let him do as much as the work as possible.  We just got a new carb in the mail tonight and my son was upset because we won't have time to work on it until Wednesday.  We also have to check over the electrical because we couldn't get the starting motor to even turn.  I have the schematics it's just a matter of finding the time.  He wants his tractor running so bad that he can't hardly wait.  I'm anxious as well but he has me beat hands down!

Working on tractors is our most favorite time together (besides him being by my side when I was coaching high school football)!

Makes me want to smile and cry at the same time!!!

I decided to buy a new carb for this tractor.  The old one had a very badly worn throttle shaft and decide it would be ok if I just bought a new one.  I'll keep the old one for now for parts. 

  It cost $60 and came with two styles of choke levers.  The carb looks and feels like a good quality replacement.  It even felt like it weighed more in my hands verse the original.

Here is what it looked like right out of the box.

20170711_185146.jpg 20170711_185154.jpg 20170711_185204.jpg 20170711_185323.jpg

The choke shaft in my hands was the one installed on the carb but I switched it out with the other one it came with.  Took only a couple of minutes to complete.  The only thing I had to watch out for was the detente spring and ball when I removed the choke shaft.

 

Here is a side by side comparison of the carbs.

20170711_191420.jpg 20170711_191333.jpg 20170711_191357.jpg  

The only problem I've had so far is the hose barb on the new carb is different from the compression fitting on the old carb.  I tried to switch the two but the new carb seems to have different threads.  Maybe metric???  Not really much of a problems all I have to do is replace the compression fitting on the tank with hose barb fitting.  We ran out of time tonight so hopefully we'll install the carb tomorrow and track down the wiring issues that is keeping the engine from cranking over.

Like you said, switch the barb on the tank and use a rubber hose. Those old steel lines are nothing but a leaky pain in the a$$.

Good to know about the metal lines.  I've never had a tractor with it on it before.

 

Ordered a barb fitting last night for $5.  It will get her Friday.  Couldn't find one locally.
