Cleaning carburetor, what to use

dacaseguy · May 14, 2019

I usually soak carbs in carb cleaner and lightly sandblast them. What do you guys use to clean carbs besides sandblasting them.

Cast iron carbs can be soaked in vinegar for a week or so to lose the rust. Wherever possible I flat-sand mating surfaces, just glue sandpaper or emery cloth (100-150 grit) to a glass tabletop or marble slab and slide across, blow the dust off every few strokes. If you must sandblast, first make sure ALL the jets are out of the body and cover so you don't resize them or clog them, and get ALL the grit out before reassembly.

I sock them in carb cleaner . Then spray them out with carb cleaner spray and blow them out with air and then poke out all the passageways with a torch tip cleaner tool. Ones that are real bad I use a Dremal tool and a wire brush or grinding stone

disassemble and soak in gunk.

never even heard of sandblasting a carb. will do more damage than good. a small bead blaster might be ok. sand don't do a thing when you need to remove varnish and carbon from passages. soak for a couple hrs. rinse with cool water, then blow passages out with air. been doing this for over forty years.

In the old days we use to take out everything that was removable and soak in apple cider vinegar. Use torch tip cleaners and pipe cleaners. On stubborn lean runners that needed the choke, toke the main jet out, put it in the cigar box on a shelf with the other leftover carb parts.

I was shocked when mEl posted he left the main jet out too. I can't believe he is as old as I am, knowing mEl he is just a fast learner.

I have an old electric wall oven sitting on a furniture dolly in my shop, If dealing with a cast iron carb with NASTY stinky deposits I tear it down and remove the float and any other delicate parts and wheel the oven outside, plug it into the long 240 Volt cord for my welder, and toss the carb parts in it at the highest temp (475) for a couple of hours.

After that and allowing it to cool, most deposits have turned to powder and can be blown away with a compressed air blowgun.

Carb cleaner and air like most have replied. One time I had a CC carb that was really bad. When I took the top and bottom halves apart everything inside was one solid chunk of rust. I chipped enough rust out to remove the brass parts with the help of heat. I soaked it in muratic acid overnight. Looked like new the next morning. Stench was BAD. Do not do it inside!! Tractor runs great.

I bought a gallon of some purple parts cleaner from Ace. I poured half of it into an empty, clean one gallon paint can and soaked the completely dissembled carb for a week. That parts cleaner is harsh on skin, so I wore gloves after washing the burning feeling off. I did brush a couple of areas with a stainless steel brush, just to ensure the parts cleaner would get all of the paint off. After pulling the carb out, I sprayed it down with carb cleaner because the parts cleaner left a film/residue. I did brake clean the exterior surface of my carb by spraying a clean rag and wiping it down. I hit it with compressed air and let it dry. I used electrical tape to mask off all holes and mating surfaces. I painted it with Case tractor paint in a rattle can. I let the paint cure for nearly four days before handling. Thus far, it s holding up great. Much better result than my last go at this.
