Hello This fall I have had a few big issues with my 17 Year Old LT1000 Tractor and it has been a struggle to keep it going. It served me well and and I like to keep it going instead of just paying $3300 for a new setup of Tractor Bagger and 42" Snow blower attachment. 1st problem was the backfiring caused by the worn timing gear (1) 17 y/o Lt1000 17 HP Kohler Eng Kaput- timing problem | Firewood Hoarders Club Then the belt was falling off the snow blower attachment due to bad bushings and bearing (1) Sears Craftsman LT-1000 Lawn Tractor 17 y/o 42” snowblower attachment belt keeps slipping off! Fix! | Firewood Hoarders Club Now the gas is was leaking from the carburetor float bowl and also where the solonoid attaches on the bottom. This problem would have been easy except I got 3 carburetors 1st carburetor from a tractor supply about $60 Did not fit even though they said it was for a Kholer engine but only the pro tractors not a sears! 2nd carburetor from Ebay about $20 The right carburetor but just did not work! Same as the last carburetor that worked when I bought the same one a few years ago! 3rd Carburetor from SearsPartsDirect and $170 bucks This carburetor worked but just like the last 2 carburetors, the throttle linkage bushing is missing!! So this works, and it does not leak gas. However there is no Throttle Linkage Bushing!!! Now the carburetor from ebay I purchased a few years ago came with the bushing! Unfortunately it fell off when changing the carbs and it is so tiny, I could not find it!! Just disapointed that I had to be extra careful not to tighten the carb down too much so the throttle can move it but the throttle is sloppy now. I can get it in the right position and the tractor works. Any ideas to make it right? See last picture brass colored hole with no bushing in it??? The bushing is part 15 in the Engine controls
Can you make a bushing to fit it? I could spin up one for you on the lathe if you want. Easy enough if you can't come up with what you need.
Thanks Anyways but I just found out those bushings are the same for all Kohler carbs and common as a common pins! I just called up my local Turf Depot and gave them the Kohler Spec # 27508 and told them I needed the Throttle Linkage Bushing and they had 8 so I bought 2 for approximately $7 bucks each! Part # 25-158-11-S Thanks for all your help!
Thats good. Well I couldn't have made that gig-a-ma-thing with the little clippie on it anyway. A simple bushing I could have certainly done for you though. Glad you found what you needed.
Well it is not over yet because the old bushing was round which snapped in the hole and the linkage went thru it and turned under the hole. The new bushing will fit in the hole but the extra bend on the linkage at the end will not go thru the bushing! Do I cut the bend part at the end off?
Oh Man, one of my buddies just helped me figure it out! They sold me the wrong bushing, it is for the other end!! I need part # 25-158-08-3 which is part # 15 and they sold me part # 17 and the both have the exact same item description which explains the mixup!! The pic below is the one I really need!!
I have to return the black ones I got and get the white one tomorrow if I can get it. So we will see.
Popped the new bushing in and the throttle is nice and smooth and even no sloppiness!! Also learned how to pinch the gas line for minimum gas line spillage and put a little plastic catch tub so no gas on the garage floor.
One last secondary fault! I used the blower without the throttle linkage bushing but in order to do that, the serrated flange nuts that hold the carburetor and the black plastic air filter housing to the engine had to be very loose. If these 2 nuts were tightened down, then the throttle linkage on the carburetor would freeze up because it would press against the engine! Then after I used the snowblower on the last storm one of the nuts fell off! I had to buy a new M6 serrated flange nut and with the new throttle linkage bushing in place, tighten both nuts down properly, Throttle now works like it should! See pics of M6 serrated flange nuts.
Hmm. You may have given me the answer to my own carb problem. ...I was wondering what that little thing did.
