DIY ultrasonic carb cleaning results
Underdog1:
Tried my Chinese ‘GT Sonic’ carb cleaner for the first time today along with Allendale ultrasonic carb cleaning solution.
After 2x5 minute blasts, a 10 min blast and finally a 30minute blast at 70 degrees my carb body still looks like this:
Basically no different to when I started, it’s all been blasted out with air so I’m confident it’s all clear, there was also a bit of sludge at the bottom of the solution which had turned brown. Basically what’s this white stuff? It was there before I started and US cleaning obviously isn’t removing it. Got another carb body in some thinners overnight so will see what that’s like in the morning. Carb bowl is sparkling but I’d already manually cleaned that thoroughly.
Am I expecting too much of my US cleaner?
Nurse Julie:
I had huge problem with white deposits when I had my carbs cleaned a few years ago. Even when I stripped the carbs over this winter, there was still evidence of the white stuff. It's has all gone now after this winters strip and clean but it was a right pain in the arse.

I had this stuff on there before I even started. As long as the carbs are good to go with the white deposits inside I don’t mind, just thinking do I need to get it all out before hey go back together?
Nurse Julie:
I would definitely try to remove it. I'm trying copy and paste the link to my thread on it.....

Maybe the soak in thinners will do something. Otherwise it’ll have to be elbow grease and scotchbrite
