Rebuilt Edelbrock, yea or nay

My son bought an amazon ultrasonic cleaner for his jet ski carbs. Works nicely, but it is not big enough for a 4 barrel. Don’t know that I can justify buying one that big.
Just buy a large crock pot, use simple green and water, boil it.
It will come clean, just don't leave it in too long, it will strip the finish off.
