TimH 105 #1 Posted October 26, 2018 Trying to find a new carb or Kit for a 4 hp K90 Share this post Link to post Share on other sites
The Tuul Crib 7,331 #2 Posted October 26, 2018 For me I would probably just buy a new carb and bolt it on but I'm not real fond of the Japanese or Chinese models because they are metric. I'm not sure about the K 90 if you can find a carb kit for it but it is worth looking for Share this post Link to post Share on other sites
ebinmaine 62,360 #3 Posted October 26, 2018 If it's not to gummed up I prefer to try to rebuild the existing carburetor first. I think they are a better built and more precise instrument overall than the modern cheap Asian replacements. If your linkage is worn very much it may not be worth rebuilding the old one. You could try placing an ad in our want ad section or contacting Lincoln at a - z tractor. 3 Share this post Link to post Share on other sites
953 nut 51,019 #4 Posted October 27, 2018 You can find new Chinese carbs and kits on . As Eric said the one thing that will make a carb a real good candidate for replacement would be a throttle shaft with too much play on it. The worn hole for the shaft can be repaired with a bushing and if you are doing a restoration and are concerned about authenticity then rebuild it. If you buy a replacement be sure the choke lever has the correct arm for your application. 1 Share this post Link to post Share on other sites
71_Bronco 1,072 #5 Posted October 27, 2018 I save tractors has a replacement for $60, not sure if it's a Chinese knock off or a decent repro. He doesnt have a rebuild kit listed for the k90, but may have one if you try emailing him. I'm sure there is someone making rebuild kits, or check ebay, there has to be some NOS ones kicking around. 1 Share this post Link to post Share on other sites

Lost Pup 172 #7 Posted October 27, 2018 I purchased a knock off for my kohler twin. Extremely satisfied with it. I did have to adapt the choke lever but otherwise a perfect fit. Share this post Link to post Share on other sites
Chris G 3,272 #8 Posted October 27, 2018 I always try to rebuild the original. But on one of the k-91's I had, I did use a Chinese knock off and overall I was satisfied with it. Share this post Link to post Share on other sites

Choke and throttle shaft look ok. Float had hole in it I had to solder. Needle was stuck in closed position. Cleaned up well. Polished seat with Q-Tip in a drill with valve lapping compound. Just going to need a gasket set. Turns out Horse has been setting for ten years. Changed fuel lines , Cleaned tank with acetone and sealed with tank sealant. New filter. 3 Share this post Link to post Share on other sites
ebinmaine 62,360 #10 Posted October 27, 2018 Well done sir! As stated above, get a hold of Lincoln and he'll be able to fix you up with a gasket set for that if nobody local can do it for you. I live in a rural area and a lot of my stuff is mail-order and he has become a preferred vendor for me. 2 Share this post Link to post Share on other sites

71_Bronco 1,072 #12 Posted October 27, 2018 I checked ebay after I posted last night, there were a few k90 carb rebuild kits. Shouldnt be an issue getting one, and that's the way I'd go personally. Good luck with the rebuild 1 Share this post Link to post Share on other sites

I always go with the OEM set, I've had better luck with them & they're not much different in price. Here's a link to a good source for them. http://www.psep.biz/store/kohler_carburetor_parts.htm Edited October 27, 2018 by Achto 3 Share this post Link to post Share on other sites

Horseoholic 135 #19 Posted November 12, 2018 bought one of those china carbs. for my H60 67' L157 horse..........it leaked worse than the old one, had to take parts from the old and implement it to the new, works like a charm, without a doubt, try to find a good kit.

rjg854 10,642 #20 Posted November 12, 2018 I tend to like using a kit. I've had fairly decent luck rebuilding them. I did put a new carb on the 16 Automatic but that was because the PO put one on, but it worked backwards. It looked as tho the choke was being used, and it bugged me.
