I realize it is extremly flammable and dangerous, however has anybody used lacquer thinner as a solvent for cleaning a carb during a rebuild? Does it remove dirt/deposits in passages? Does it remove the plating? (I am not looking to remove it). If this is a no-no can anybody reccomend anything else that will work? I don't plan on rebuilding carbs for a living so I don't want to invest in a carburetor dip tank. I tried the 1 gallon can from the parts stores about 5 yrs ago and found it useless since you can't put the carb inside of it.

When you disassemble the carb (float bowls, metering plates, etc), the parts will fit inside the gallon can basket, at least a Holley 750 did....

A broken down Holley will fit in a gallon can, but an Autolite 4100 sure won't. My solution was to buy two cans of the carb soak and a big cheap stainless steel cooking pot. A 4100 carb fits that just fine.
Real carb soak is more like paint remover than anything else. Nasty caustic stuff, but I don't know of anything better to really clean a carb.
Though lacquer thinner is quite volatile, it's basically just paint thinner and almost the same thing as spray can carb cleaner. Helpful, but it has limited effect on really nasty deposits. Yes, you can use it, just don't expect nearly as much effect as carb soak. I have an air-pressurized can I keep filled with lacquer thinner that I use just like carb cleaner. It works just as well if not better and I can refill it myself from a 5 gallon can. I use the sprayer for all kinds of stuff including final parts cleaning before paint or assembly. (Not while smoking)

You can buy Berriman's (sp) carb cleaner in a gallon paint bucket. It's made just for what you are doing. I would go that route. I have used it and it works great. Disassemble the carb drop it in and let it sit overnight.

I love laquer thinner, but it is too volitle let stand open over night.
