Using Ultrasonic
« on: March 25, 2018, 11:37:44 am »
I broke down and ordered a digital heated ultrasonic cleaner.  I've read plenty about which solutions to use.  (There are some strong opinions out there!)   But, I haven't seen a whole lot about how long to cook a carb in one.  Searching through here someone I saw one post where someone was putting it through several 5 minute cycles.   That's it.  So, how long should one cook a carb?  And, at what temp?  Thanks.

Really depends on the item being cleaned, the solution and the power of your ultrasonic. Carbs are tough to tell because the tiny passages trap the dirt and don't allow the debris to float away. They often need to be probed with a wire and flushed with carb cleaner to get all that junk out.

A lot of the cheap ultrasonics have a 5 minute timer because running them longer can overheat the transducers. Be careful repeatedly cycling your cleaner and let it cool if the outer housing gets hot or you start tripping any thermal protection the unit may have.

You also must be careful with the cleaners you use. Solutions with high alkali content will etch or stain carburetors. Add just enough to get the job done. And never forget and leave parts in the unit when it has shut off. That will cause staining or loss of anodized surfaces also.

Lastly, remember that the cleaner removes all oils and any steel parts can flash rust so needles, levers and springs need to be thoroughly dried or sprayed with some sort of protectant as soon as they come out.
We just drag them down..... Until they're just like us !!!  BNL

Guy in the CR-G said this stuff is the best he ever used in his.  Blew away all the other mixes used like simple green etc  he said. Made for the job at hand.

So thought I would save and share this here too.
