New Member that needs help w/122
 

Hi, I'm new to this site. and I was told this was the place to be if I had questions about Cubs. I don't know how to get this message to the right person(s). I've cut a lot of grass w/Cubs but I don't know anything about working on them. It's pretty sad but I guess it's better than never learning at all. My Cub starts, however after its in gear and moving, it dies. Choking it only helps for so long. Some running periods times are short and some long. I think it's two issues. An overheating problem, when it's running long and second, I've found the throttle linkage thats attached to the top of the carb shakes forwards and backwards when its running. Theres a spring attached to the bottom that seems to also be loose. I'm not sure if its the right spring or just needs to be adjusted. If its a carb problem, I know nothing about carbs and what screws do what if they need to be adjusted. The frame says its a 122. It's a 12hp kohler engine, Model # Co43210. Spec. #4759B. The back of the cub Serial # 213703. Would someone tell me if this is a 122 or something else. I'd really like to hear opinions about these problems that I'm having. Other then this annoying running problem, it's a great tractor. P.S. I know everyone love pics, I'll have some soon. Thanks.

Welcome Jeff :beerchug:

I have a 122 also. The running problem would lead me to check out the carb. There is probably dirt , grime or other "stuff" in there. Do you have the sediment filter on the gas tank? ( the glass bowl with fuel shutoff ) That could be filled with stuff too.

The shaking throttle linkage is part of the governor assembly. Is your rpm going up and down?

You mentioned over heating. Make sure you use a straight 30W oil, preferably one designed for air cooled engines. Also, if you remove the tin work, you can clean the dirt and grass clippings from the fins.

Do you have a manual for the 122? If not, we have them here on the forum.

Jeff

Welcome to OCC. I can't tell if it's a 122 unless you can give us the first half of the serial number. The top half of the throttle linkage where it hooks up to the carb should be pretty tight. Sounds to me like you need a carb rebuild.

wow, that was quick! yeah I have the glass bowl w/fuel shutoff. Yes, rpms have been up and down. I'm good on the oil, and I have a brand new air filter w/the green foam piece around it. No I don't have a manual. And because I'm so new to this I have no clue where to go to get it. You'd laugh if u knew how long it took to learn how to post something. LOL! I'll glagly take all the help I can get

Thanks for all the help. Looks like I got a lot to read. I guess its homework time. I'm sure I'll have more questions if so I'll stay in touch!

Jeff,
Sounds like a nice 122. We all love pics. Got any, hint/hint. :biggrin2:
I'd start with a carb cleaning as the others have suggested. Welcome to OCC :beerchug:.

IHMan,
He probably gave the whole serial number. On the older cubs, the beginning numbers, kind codes, etc. weren't added till later. I remember reading somewhere that IH had kind codes for each model, but they weren't added to the actual serial number tag till later. Paul Bell had written it. I know the longer serial numbers were on the wide frames, but they actually came out alittle earlier IIRC, maybe the 1X6/1X7 series????? I just sold a 124 and it had the XXX,XXX serial number on the rearend only.

:Welcome2:

Good advise and let us know how it works out for you.

Jeff122,
Welcome! These guys are like sharks on fresh blood! They will be all over this for you:) That's a crude compliment guys, but Jeff heard correct this IS the place to be for cub info and support. BTDT.
Keep feeding us information and your Cub will be running well soon.
Regards,
Chris

Still working on the 122
 

I have to say thanks again for all the helpful advise. I agree it definitely wouldn't hurt to have the carb cleaned. But for starters I did clean out the glass bowl (it needed it) then started it to see what would happen. It died after 1 1/2 min. when it was in gear. I wasn't surprised. Next I read in the manual it was the high speed screw on the carb I messed with. I turned it clockwise then started it again. I drove it for 20 min. and it didn't die. Could it have been that easy? I doubt it! On the positive side, I actually got some grass cut. However I didn't take it out of first gear. And yes, the serial # was only 6 digits. Would someone tell me what Kohler engine I have by giving this #043210. Just in case I do have to get new parts. How hard is it to replace the engaging lever button. Mine broke while someone was changing the belt. I have a feeling this is the year I’m going to be learning a lot about Cubs. LMAO!:biggrin2:

I make brass PTO buttons, they are easy to replace and the brass one will lasty for years.

That's a picture of a K301 Kohler laying on it's side. See the "lump" on the bottom of the oil pan? That is one way to identify a 12 hp from a 10 hp Kohler ( 10 hp is flat )

I'm not sure if thiss is your problem but I know on my 102 it was down after a short period even after the Carb rebuild it would still do the same thing turned out it was my coil replaced it with onother one I had laying around and it hasn't done it since... Just a thought

1st. things 1st.,

Ask alot of questions for the # 122. This way I won't have to since I have a # 122.

When I 1st got my # 122 it started dying on me after 10min., start right up again & kept on killing on me every minute or so? Start right up again. When the engine cooled off it would run for 10min., & the problem started up again.:bash2:

Here's what I did for a quick fix for MY problem & it worked, knowing deep down inside I HAD to rebuild the carb.

I cleaned the bowl on the carb, disconected the fuel hose & shot some carb spray into it & cranked the engine for about 10sec., & did it again. I removed the gas tank & flushed it out & added 1 quart of new gas with some Sea Foam in it. Ran it dry & the motor NEVER stopped.

This was a temp., fix & it worked for about a month. Then it happened again.:bash2:

I then ordered a re-build kit from my local NAPA store & rebuilt the carb. Never had that problem again. Now I NEVER re-built a carb in my life. I took my time & followed these instructions; http://mgonitzke.net16.net/tools/carb_rebuild.pdf

If I can do it so can you. Just take it slow & now its easy & well worth it.

No one has responded to the serial numbers, Frame number 213703 Was made in Sept 1967 for a Cub Cadet 122 Kohler Model number and spec number
shows it the engine made in 1967, a K301, 12 hp. I take it that you saying frame you mean off the rearend. Which would be the correct location for a 122. Allso the hood should say 122 on it also.
