Questions for expierienced ultrasonic cleaner users

[Ricko1966]

I just bought a fairly big ultrasonic cleaner. I heard they are the latest and greatest for cleaning carbureator bodies for rebuilds. I've read you should never allow parts or baskets to touch the sides or bottom of the pan.I've read that best results are when your parts are in the middle of the solution. I've also read to preheat my cleaning solution instead of letting the unit bring it to temp. So here's what I'm thinking, lay 2 wood slats over the top of the pan opening and use all thread with double nuts top and bottom to hang the carbureators in the center,side to side and top to bottom,second Idea was hang with fishing line from wood slats. Planning on using 50/50 pinesol and water. Thoughts?advice?

Everything we've used in the ultrasonic cleaners at my last place, semi-conductor company where I was the lead senior maintenance tech, were all at room temp and not suspended in the cleansing solution. Our tolerances and cross contamination issues were very very minute. Tolerances of less than half the thickness of a human hair over a 22" span measured at 7 different points and cross-contamination levels less than 0.01ppb. But yes, if you're looking for a full-on clean on all surfaces you'll want it to be suspended in the solution and rotating it once the cleaning power seems to be slowing down.
