I just received another request for fixing B&S 6.25 sidedraft carburettor over this weekend, so I decided to do a show-n-tell to share with you folks:
This is how the Walbro LMS carb (clone, chinese stuff) looks like before the restoration begins:
As my Branson 3L ultrasonic cleaning machine is out of commission, I'd had no choice but resort to the measure of using my rather low-powered, jewellery cleaning one (approx. 0.75L):
3 rounds of cleaning with water and a few drops of dawn clean things up nicely:
(picture after 2nd round):
These are the pics of the end result after 3 rounds of cleaning (total time around 15 mins):
Beast of all: ultrasonic cleaning will break down/disperse any debris into very fine dirt, including those that may have clogged your otherwise very find jets and passageways. Patience is key, esp. when using low-powered ultrasonic cleaning machine. Give yourself sufficient amount of time and keep changing out the filthy water with fresh new one until the water is clear (that's the last pass).
With a fresh new gasket kit, the carb is now running fine on the B&S mower.
