Can I save this carburetor?

Recommended Posts

ebinmaine

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....?

Have you tried soaking it in vinegar?

Leave it in lacquer thinner for a while.

Lacquer thinner will clean the hair clean off your carcass! 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! :)

that carb probably works better than those 9.99 ones on ebay

They have it at Home Depot and any paint store. Used widely to dilute paint for spraying still.

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.

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/ :eusa-think:.

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.

I'm thinking that carb aluminum is corroded to the steel/ brass parts

I haven't done it but I know a few folks who use those ultrasonic cleaners with lemon juice for old crusty carbs

I do this, but with EvapoRust. 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.

:text-yeahthat:    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.

I was thinking vinegar, too.

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.

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.

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
