Float must be stuck

Tractorcedric · Apr 15, 2020

This was on a another guys tractor, I just could not resist checking out the carb. How much time does it take for one to get this bad? It took a lot of scraping and brushing, but I think it will work again. Float was still good. It took a long time just to get the needle out that went to the bottom of the bowl.

Purchase the nastiest full immersion Liquid you can find. It will take at least a half gallon size. follow the directions. No scraping. Jim

If it is cast iron, boil it in lye water. Change it until it stays clear. Use torch tips each time & blow it out good too.

I have a few mini steam engines I kept in a plastic tote.
Somewhere down the line,, water got in the tote and rusted them pretty bad.
When the smoke clears and the dust settles, I'm gonna go to HF and get
their small bench top sand blast cabinet. There are several choices of
blasting media, sand, rough sand, glass beads, crushed walnut shells.
One of those should work with out causing too much damage.
A blast booth with glass bead would work real well on that Carb.

I agree it would clean it if it was going to be a wall mount trophy, but that has always packed nearly permanent sand/grit into tiny passages. Not a flame, it is the result of trying to fix what somebody else sand blasted. Jim

Electrolysis works good to get rid of rust. There was a gentleman from Colorado (?) a few years ago that had a series of threads on how to do it. You used a battery charger, a plastic tub, a liquid that will conduct electricity & a sheet of lite metal to remove rust. I've got the process written down somewhere & have used it. It works great. Does anyone else remember it?

soak in muriactic acid for a couple of hours, neutralize in water, blow dry. it will look like new.

No matter what you do, that carburetor will leave a bit of doubt in your mind. At the first sign of trouble, it could be the carb, I thought I got it perfectly clean, maybe not. Maybe those doubting thoughts never enter anyone else's mind, but they always reside in mine after one of my repairs. gobble

Wish I had posted this earlier! I just did a lot of scraping and sanding. If it doesn't work I will give it a soaking. Thanks for all of the helpful info. That is why this is my favorite place to surf!!

Soak it a long time in strong, hot stuff, rinse, then soak it again in strong stuff. Remove any brass fittings and then blast it after dry with a medium abrasive. You have to get down to the base metal and leave no loose debris. It will probably work OK if everything is clean.

I understand. Not every thing works for everybody.
And two people working on the same problem can have
totally different troubles/solutions.

When they get rusted that bad, I look for a better one.

the marvel schebler . the thing is carb cleaner don't do much to rust. probably have to hot tank it at the local rad shop. but never know it might be loose stuff.

I have rebuilt several that were that bad. Immerse in boiling water with some detergent added. Let it boil for maybe an hour. Dry it with compressed air, and then go to the bead blasting cabinet. More cleaning will be needed, but that carburetor can be made to function AND look as good as new.
