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
 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

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

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!

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
