Jstrand 18 #1 Posted April 21, 2022 Hello, New to this tractor and i'm looking for a new carb for my H55A-1170 or something that is compatible with this engine. Any parts pages or anything along those lines would be very helpful! Thanks, Share this post Link to post Share on other sites
Jstrand 18 #2 Posted April 21, 2022 Also, which time of fuel do you guys use? I know older engines don't like the fuel at the gas pumps. Thanks! Share this post Link to post Share on other sites
8ntruck 7,016 #3 Posted April 21, 2022 I think several folks here have used a Kohler carb on their Techy engines with some success. Somebody will be along shortly with details. As far as fuel goes, you will want to find some without alcohol mixed in. Typical pump gas has somewhere between 10 and 15 %. Alcohol free recreational gas is what you want. The alcohol in the modern gas is what bungs up the old fuel systems that were not designed for it. 2 1 Share this post Link to post Share on other sites

There are plenty of aftermarket carbs out there for the Techy's. Just look the pictures over good do to ensure that every thing looks the same as the one you have. One example: https://www.amazon.com/Carburetor-Carb-Tecumseh-Horse-TILLERS/dp/B0725RXBK9/ref=asc_df_B0725RXBK9/?tag=hyprod-20&linkCode=df0&hvadid=198123788296&hvpos=&hvnetw=g&hvrand=8306905456561669747&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=1028057&hvtargid=pla-349807863090&psc=1 Yes definitely try to use ethanol free gas. In my area I have to use the 91 octane to get away from ethanol. Edited April 21, 2022 by Achto 1 1 Share this post Link to post Share on other sites
WHNJ701 4,165 #5 Posted April 21, 2022 (edited) If you have the original carb for the h55 lauson, I believe that's a pretty rare carb with the way the adjustment screws are opposite of the aftermarket ones. @formariz might be able to add to this Other carbs will work it's a tight machine to work and adjust Edited April 21, 2022 by WHNJ701 1 Share this post Link to post Share on other sites

Could you take some pictures of your wiring? I would like to copy it since it looks like we have a similar tractor? Thanks, Edited July 26, 2022 by Jstrand Had more to ask.
