Dadof2 5 #1 Posted September 17, 2022 Hi, looking for a replacement carb for my HH-100 115145C. I bought one off Amazon that said it was for HH-100 and HH-120 engines but it is not as long a my original and the choke lever gets caught on the ignition coil. Has anyone for a new replacement carb for this engine? Thanks, Jeff Share this post Link to post Share on other sites
ebinmaine 63,127 #2 Posted September 17, 2022 What's the tractor ? Do you have the original carb? Why replace instead of clean and rebuild? @Pullstart has adapted Kohler carbs to techies. 1 1 Share this post Link to post Share on other sites
Pullstart 59,709 #3 Posted September 17, 2022 Yes I have, with great success! It wasn’t that challenging either, but it was a smaller engine size… 1 Share this post Link to post Share on other sites
pfrederi 17,147 #4 Posted September 17, 2022 Some 10 hp Techies need a spacer plate to hold the carb out away from the block It is a tapered plate the yellow thing in the picture. 1 Share this post Link to post Share on other sites

Dadof2 5 #6 Posted September 18, 2022 Eric, I have the original carburetor and have tried cleaning it. It stays running on full choke only at this point and I am sure I cleaned all of the holes. I also had already bought a new one that was supposed to work for HH100 engines but I have a clearance problem as the choke lever is about half an inch closer to the block compared to the old one. I will try to rebuild it. Paul, I picked up a plate on Ebay just in case my rebuild doesn't work. Thanks for the part number! Share this post Link to post Share on other sites

Did you remove it? Did you soak the carb? In what? For how long? Did you spray at least 2 whole cans of brake clean through the ports and galleys? Share this post Link to post Share on other sites

The K181 carb will fit and that is what I ended up using on my HH120. My apologies for the confusion. Don Share this post Link to post Share on other sites

I can't speak for the HH10 but .. The Tecumseh OHV160 is smaller cc than the Kohler K341. It seems reasonable that a carb from a Kohler 14 or even a 12 horse would produce usable power on the Tecumseh OHV160. It would be interesting to do real world testing with a Charger 9/10 with both carbs to see the actual results. Share this post Link to post Share on other sites
Dadof2 5 #14 Posted September 19, 2022 (edited) Hi Eric, The other night I just disassembled and cleaned with carb cleaner. Today I did ultrasonic cleaning, used carb cleaner and sprayed compressed air through ports. Is there a Welch plug? - No Did you remove it? - Yes Did you soak the carb? In what? For how long? - Put it in an ultrasonic cleaner for 25 mins with 50% water 50% simple green. Then it soaked for 4 hours in that solution. After that I did another ultrasonic cleaning but just water this time. Did you spray at least 2 whole cans of brake clean through the ports and galleys? - After ultrasonic cleaning I sprayed about half a bottle of carb cleaner through the ports and them blew it dry with compressed air and reassembled it. Does brake clean do a better job? Edited September 19, 2022 by Dadof2 posted before finished writing Share this post Link to post Share on other sites

Given that secondary cleaning I'd be tempted to reassemble and install. 34 minutes ago, Dadof2 said: Does brake clean do a better job In my area carb clean is nearly twice the price of brake clean. Carb clean leaves a residue that I do understand lubricates the carb pivot points. Share this post Link to post Share on other sites
Dadof2 5 #16 Posted September 19, 2022 After the second cleaning/install I am still having the same problem - slow running engine and dies when I take it off choke. Is it possible that it is something other that the carb? Share this post Link to post Share on other sites

Dadof2 5 #22 Posted September 19, 2022 So I was able to get it running today and drove it around for a bit and everything was normal until I tried to reinstall the air filter and then it died. I have not been able to get it started again. After trying to run it for a bit I pulled the spark plug to see if it was dry and it was wet with gas. I've tried shooting starting fluid directly into the engine and it still did not start. I am charging the battery and will go pick up a new spark plug, which I am hoping is the problem. Will let you know how it turns out. Thank you all for your help so far. 1 Share this post Link to post Share on other sites

Dadof2 5 #24 Posted September 19, 2022 (edited) Not sure, I bought the tractor in 2019 and can't remember if I changed it. I checked for spark and it there is one but it is faint (see below). Are you thinking it might be something else? Edited September 19, 2022 by Dadof2 Share this post Link to post Share on other sites
ebinmaine 63,127 #25 Posted September 19, 2022 Absolutely worth changing the plug. The other day, and in times past, I've gone to way too much trouble diagnosing "issues" that were ridiculous like bad plugs. 1 Share this post Link to post Share on other sites
