ebinmaine 72,672 #1 Posted June 6, 2020 This is a Kohler carb from the Charger. It's stuck. Like wicked stuck. That tractor sat unused for 25 +/- years and the moss on/in the seat gave notice it was in a wet environment. The throttle and choke shafts are completely frozen in place. I left it in the carb cleaner dip for 2 months with no visible change. Other suggestions....? 3 Share this post Link to post Share on other sites
The Tuul Crib 7,339 #2 Posted June 6, 2020 Have you tried soaking it in vinegar? 2 Share this post Link to post Share on other sites
formariz 12,045 #3 Posted June 6, 2020 Leave it in lacquer thinner for a while. 2 Share this post Link to post Share on other sites

I used to use it to clean automatic transmission parts. I don't know if you can buy "Lacquer Thinner" any more because of the VOC laws. They renamed it wash solvent at Napa. After the thinner, vinegar or CLR. Straight ice machine cleaner or Nu brite coil cleaner will work to but you'd have to leave it out in the woods whilst it's agitating! 1 Share this post Link to post Share on other sites
WHNJ701 4,165 #5 Posted June 6, 2020 that carb probably works better than those 9.99 ones on ebay 2 1 Share this post Link to post Share on other sites

squonk 43,819 #7 Posted June 6, 2020 We had to throw out all lacquer based automotive paint years ago. It was about 5 yrs. ago when they started labeling it wash solvent. May have just been a Napa thing on the name change. 1 Share this post Link to post Share on other sites
WVHillbilly520H 10,376 #8 Posted June 6, 2020 I prefer MEK as it is stronger on tough gasoline varnish but it will destroy the rubber tips on the needle valves... BTW Duplicolor Paint Shop quarts at Adavance, AutoZone O'Reilly's ect is "lacquer" paint...https://www.duplicolor.com/product/paint-shop-automotive-lacquer-finish-system/ . 2 Share this post Link to post Share on other sites
pfrederi 18,670 #9 Posted June 6, 2020 I made a batch of my own a few years go. MEK, Lacquer Thinner and Xylol (maybe a bit of acetone )...use personal protection. Cleaned what I qwanted. But it evaporated after some time. Been using Berrymans' since. 3 Share this post Link to post Share on other sites
squonk 43,819 #10 Posted June 6, 2020 I'm thinking that carb aluminum is corroded to the steel/ brass parts 1 Share this post Link to post Share on other sites

WHNJ701 4,165 #12 Posted June 6, 2020 I haven't done it but I know a few folks who use those ultrasonic cleaners with lemon juice for old crusty carbs Share this post Link to post Share on other sites

It works wonders. Eric, if your local parts store sells what I mentioned above, pick some up. About $30 a gallon, but you don't have to use much and it is reusable. Works wonders. 1 Share this post Link to post Share on other sites
JCM 10,202 #14 Posted June 6, 2020 I used EvapoRust on my Super A gas tank with great results, patience and several applications did the job. I was skeptical, would use it again. 1 Share this post Link to post Share on other sites

953 nut 59,999 #16 Posted June 6, 2020 This may be a good "E-Tank" candidate. You have a steel shaft passing through an aluminum body, can you say Dissimilar Metal Corrosion? It all starts out as an electro-chemical reaction and an E-Tank is an electro-chemical reaction that will set you free, just connect the wire to the steel parts. https://www.appmfg.com/blog/4-facts-on-dissimilar-metal-corrosion 1 Share this post Link to post Share on other sites
D_Mac 9,302 #17 Posted June 7, 2020 You saw how bad the transmission was on my Lambert project. I am a true believer in soaking it in vinegar. Pull apart what you can and submerse it all in vinegar. After a week if it isnt clean, dump the old and pour in some new and let it soak again. It will clean up. Share this post Link to post Share on other sites
ebinmaine 72,672 #18 Posted June 7, 2020 Several great suggestions here... Almost makes me wish I had a few different carbs to try things... Share this post Link to post Share on other sites
tom2p 2,394 #19 Posted June 7, 2020 also use EvapoRust with great results it's reusable and biodegradable worked so well I began to look for corroded / rusted items to clean up also tried white vinegar / salt mixture - worked - but not as well as EvapoRust 3 Share this post Link to post Share on other sites
