Can a LCT carb be cleaned in white vinegar?

I had an issue with a LCT carb on my Husquavarna machine. It would fire off but when coming off of choke it would die out. I ended up changing the carb with another but would like to have a spare in reserve (I can order out a repair kit if so). I was thinking of letting it sit in a container of white vinegar for a night or two. I would then shoot all openings with carb cleaner and blow out with air. The part that worries me is that it has plastic pieces installed from factory that will not come off. Worth doing or not? Thanks all!

40% pinesol 20% simple Green and 20% warm water

Apple Cider vinegar has worked great on rusty gas tanks. No experience in carbs

OK, something which was recommended to me by a small engine wizard who lives on a boat in the Sacto. Delta. I haven't tried it yet, but makes sense to me:

1. Buy a crockpot at Goodwill, Salvation Army, etc. (I just did.);
2. Take the carb bowl off (or not); and
3. Fill the crockpot with ATF and "Cook" your carb in the crockpot on low temp for as long as you think necessary.

Supposedly, ATF gets into and will clean everything and also recondition the carb seals.

I would set up the crockpot outside and not under anything burnable because I don't know if ATF would ignite.

If you have ever heard of such a thing, please post here. If you do it before I do (me on the carb for a rear-tine rototiller), please post your results.

Try an ultrasonic cleaner. I recently bought one at Harbor Freight, the 2.5L model.

Here's the results after three, 480-second cycles.

No pre-treatment on the carburetor and unheated solution (70% lemon Pine-Sol, 30% distilled water).

Never thought about ATF but that makes sense since it's very high in petro-detergents. I have used lemon juice water and simple gren and boiled them in a pan and worked well on old crusty carbs
