8ntruck 9,021 #1 Posted May 24 Looks like I've got some carb work coming up this summer. An ultrasonic cleaner would be a handy tool for this. HF has one about the right size for a reasonable price. Anybody out there have comments or advice on this subject? 1 Share this post Link to post Share on other sites

adsm08 4,742 #3 Posted May 24 Watch which solvents you use. Many common ultrasonic solvents are caustic to aluminum. There is one on Amazon that is aluminum safe. Not cheap, but better than ruining the carb you are looking to save. https://www.amazon.com/Ultrasonic-Solution-Carburetors-Cleaning-Immersion/dp/B09KK6KR3Z/ref=sr_1_1_sspa?crid=MW4TT953L7DP&dib=eyJ2IjoiMSJ9.Hf_fBUuXW1HjooHlm4YwrBUClH2-3mM_H0HsbKVuqsEr6xWToJl7pLZH2SE2-xMxl9-GXlWUOxmOjCVfWK65n1QUWwDHE-Ig7OIPL9WTQ7WVsFmSWxodHSxVfb-U8qD0SaaO8UlL2IsXuXlpV38sxnOn_rDrwLSlySXPMKkzkZbrvs8yh8oPNdujjtpF7PlnBxsgibVw3D4OY6A5Qbz4ibIW5qZgP3SpbVhX0xBIJ4io4_dLZ6zXkrlj3nl2biQYHbtYIvG4K-00gcY69oNCZULueCRC2vA5DavITXrx-r4.8PaEza685VoiKldJEjDUbJ954mL2_u1HO3n2B5tZcj0&dib_tag=se&keywords=ultrasonic%2Bcleaner%2Bfor%2Bcarburetors&qid=1779653786&s=automotive&sprefix=ultraso%2Cautomotive%2C157&sr=1-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&th=1 2 3 Share this post Link to post Share on other sites

Handy Don 16,909 #5 Posted May 24 (edited) I was gifted the HF 2.5L at Christmas. I’ve cleaned three carbs and a few other things and I’m pleased. It came with some cleaning powder that is caustic to aluminum so I’ve been using Simple Green Pro (the purple stuff) on anything aluminum. One “oops” was forgetting I had a K181 carb “in the soup.” The machine turned itself off just fine, but I remembered it was there only three days later. The carb was clean as I’d hoped, but the “soup” had darkened the entire surface of the carb to resemble aged bronze! I plate sanded the faces of the flanges and the regular aluminum color came right back. The aluminum bowl, however was its normal color--clearly different alloys reacting differently. Moral: Don’t forget to take stuff out and rinse it! Edited May 24 by Handy Don 10 Share this post Link to post Share on other sites
Brockport Bill 2,407 #6 Posted May 25 how many minutes do each of you run the unit to get your item clean? how many minutes can your machine operate in cleaning cycle before it times out and has to be re-started? thanks. Bill 1 Share this post Link to post Share on other sites
oliver2-44 11,609 #7 Posted May 25 (edited) My cleaner has a 30 minute cycle. I typically run carbs 3 times. More on really dirty ones. Edited May 25 by oliver2-44 3 1 Share this post Link to post Share on other sites

And use hot water if you dilute the cleaner, and use the heater on the unit while in use.... 1 Share this post Link to post Share on other sites

Bill The unit I posted a picture of above has a timer for 35 or 40 minutes. On an average cleaning I'll do 3 or 4 sets of that. I've had particularly nasty cases where I've left a carb in the lacquer thinner for a couple weeks and cycled the machine a dozen times or more. The usage alone will generate some heat. Not much, but definitely a noticeable change. I do NOT use the additional heat because of the fire potential. 2 1 Share this post Link to post Share on other sites
Handy Don 16,909 #10 Posted May 25 (edited) The HD 2.5L timer has a max of 8 minutes with or without heat. The worst carb took four sessions with some manual cleaning in between on stuff loosened by the machine. I must also point out that the tank is barely deep enough for full immersion of the K181 and B&S 12hp carb bodies so if larger items are in your plans, you might need separate passes in different orientations. To me, though, keeping the lid on while it’s cleaning helps avoid evaporation of the solution. Edited May 25 by Handy Don 2 Share this post Link to post Share on other sites
CasaytheMann 169 #11 Posted May 25 I have the Vevor 6 liter. If I were to make one recommendation, it would be to buy the biggest one you can afford. 3 Share this post Link to post Share on other sites
