New Ultrasonic Cleaner

I have had 2 4bbl carbs on the shelf for 2 - 3 years now.

I typically dunk carbs in carb cleaner but I have heard such good things about Ultrasonic I figured heck it's only money.

I found one that seemed big enough to hold a 4bbl

And it does! (No I would not put the carb in assembled)

I have not tried it out yet on a carb, but maybe after Mega Mopar at Bandamere next weekend

It was about 100.00 from Walmart, 150.00 from Amazon.

It has a heater and timer, 9.5L capacity.

Now some questions for the ultrasonic gurus...

What solution would you use?

It came with a basket any issue with putting the carb in the tank without it?

Any do's or don'ts?
