oldlineman 1,495 #1 Posted May 16, 2017 Hi guys just wondering if acetone or paint thinner would make a good carb soaking cleaning fluid. Thanks for your shareing of your knowledge as always. Bob Share this post Link to post Share on other sites
953 nut 57,904 #2 Posted May 16, 2017 I always use Lacquer Thinner, keep it on hand for cleaning spray guns so it is handy and works well. Don't think paint thinner would do the trick. 1 Share this post Link to post Share on other sites
oldlineman 1,495 #3 Posted May 16, 2017 Thanks 953 nut would acetone be the same as lacqure thinner, I am not real familiar with these products. Thanks 1 Share this post Link to post Share on other sites
953 nut 57,904 #4 Posted May 16, 2017 The only thing I have used acetone for is cleaning up after doing fiberglass work. I think it is a lot more volatile evaporates real fast) and don't know if it would be any better, but I do know it cost about four times what lacquer thinner does. 3 Share this post Link to post Share on other sites
JPWH 6,251 #5 Posted May 16, 2017 I have tried acetone when I ran out of lacquer thinner. Lacquer thinner is much better. 1 Share this post Link to post Share on other sites
Achto 28,777 #6 Posted May 16, 2017 I use Berryman's carb cleaner, about $20 per gallon, can be bought at Wal-Mart. This stuff will clean every thing off of an old carb. An important note: Make sure that you do not leave any thing that is not made of metal on the carb, it will be gone after soaking your carb. 10 Share this post Link to post Share on other sites
JPWH 6,251 #7 Posted May 16, 2017 Is the Berryman better than the Gunk? I haven't used either one. Share this post Link to post Share on other sites

I've also used these products to remove paint build up on a spray guns. Like I said, if it's not metal it will be gone. I finish up by spraying parts down with brake cleaner & drying off with a blow gun. 2 Share this post Link to post Share on other sites

oldlineman 1,495 #10 Posted May 17, 2017 Thanks all, I think there is some great information here and I think I will try Berrymans or lacquar thinner. 1 Share this post Link to post Share on other sites
joel_400 59 #11 Posted May 17, 2017 I use an ultra sonic cleaner with water and a bit of cheap simple green knock off. Have had great luck with that. Then a bit of brake clean and air to blow it out and dry off. I've even had seized up carbs and throttle bodes free up after running a few cycles. Not sure how much they cost any more but mine was free and almost fits a four barrel. Just have to flip it over to get both sides of larger parts. Share this post Link to post Share on other sites

tims tractors 119 #13 Posted May 17, 2017 I,ve used Berrymans for 30 years good stuff. If using on a carb rinse with hot soapy water rinse again clean water an blow out all passages. 3 Share this post Link to post Share on other sites
r356c 375 #14 Posted May 17, 2017 (edited) A flea market or garage sale crock-pot makes a good hot tank for Berrymans or Gunk. The flash point of thinners would be too low for me to use them around heating elements. Edited May 17, 2017 by r356c Safety concern. Share this post Link to post Share on other sites

Lacquer thinner in my opinion works better than carb cleaner does. Acetone works as an octane booster in street cars. Ultra sonic is probably the best. Use with a little lemon shine and clean out with brake cleaner. Only draw back is the cost unless you have a 1/2 dozen carbs to clean. Share this post Link to post Share on other sites
ohiofarmer 3,333 #16 Posted May 17, 2017 Most of what is in carb cleaner IS lacquer thinner. Berrymans may have a little MEK thrown in to make it hotter.I start out with straight gasoline to dissolve all the oil and grease away. the reason for this is to just leave the stubborn stuff for the expensive carb cleaner. No sense in wasting the cleaning power of the more expensive stuff by dissolving grease and oil into your soak bath Lacquer thinner will dissolve non-ethanol gum and varnish better than the grey crap left behind by the ethanol gasoline. Motorcycle carbs are notorious for small passages internal to the type.By accident, i discovered that this stuff will work, albeit very slowly to soften things up. You can actually see bubbles coming out of the passages for a half hour or so when it is working. http://www.crcindustries.com/products/freeze-off-174-super-penetrant-11-5-wt-oz-05002.html Years ago, the carb cleaner you bought was as hot as fire and worked much better than what we have today..I almost forgot, this stuff probably does the best job of all, but it is really messy to work with. I think it would go better for me now as i have much more experience with carbs. Read the reviews and note how many are five star. https://www.amazon.com/Yamalube-Carburetor-Cleaner-Dip-oz/dp/B002GU4SPA 3 Share this post Link to post Share on other sites

We had this discussion before where Berrymans had to take some of the VOC's out of their product to make it more "environmentally friendly" but it reduced it's effectiveness. Still is works good for me and a can lasts a long time. 1 Share this post Link to post Share on other sites
Tim.0 39 #18 Posted May 18, 2017 I use the gallon carb cleaner with the metal basket. Not sure what brand it is and have had it for a long time. Preclean, disassemble, let sit over night, clean with brake clean, and blow out. 2 Share this post Link to post Share on other sites
dcrage 629 #19 Posted May 18, 2017 Acetone is a 'polar' molecule (similar to water) making a good solvent for similarly polar molecules. Acetone is a GREAT solvent for removing water residue (i.e. drying something that was washed with water). This makes acetone not suitable for dissolving gunk left in carburetors which are mostly large organic non polar hydrocarbons. 1 Share this post Link to post Share on other sites

Actually, I just used it as a gasoline additive in the trusty CB750 that had an overflowing carb due to a sticking needle and seat valve. It cleared up without need for disassembly. 1 Share this post Link to post Share on other sites

Man, I wish you'd told me this earlier. My '81 CB750K is currently undergoing a partial carburetor overhaul to solve the same problem. Oh well, live and learn.

The methyl groups on the one end do offer some solubility for non polar molecules...not great, but still somewhat universally functional as a general purpose solvent. I'd imagine the old cleaners were chlorinated solvents, as are some brake cleaners too. Nasty stuff and unequivocally harmful to your health. Always use sparingly and follow the labels.
