How To Soak Motorcycle Carb For Cleaning
Many years ago I purchased a carburetor cleaning arrangement from Napa. Was a gallon bucket with a steel handbasket to soak carb parts in for rebuilding. The stuff had a distinct smell common to auto garages and machine shops when I was a child, nosotros'll say 40 years ago, it was a mutual thing. I take come to detect that this soaking solvent that was used has been stopped due to enviormental issues. Would soften and desolve #2 permatex and would clean parts unbelieveably if soaked overnight.
Whats everyone using to soak out carb bodies before rebuilding today? I did an internet search and the solvents available with the soak blazon organisation seem to be not effective compared to the older systems per user comments.
Just went through hell with a motorcycle carb that plugged up from setting for 4 years. Took 3 disassembles with several cans of droplets type carb spray cleaner, compressed air and a piece of MIG wire to unplug it and get it running...Whats the easier way to go every bit in soak information technology and assemble it....
On all my race carbs I apply lacquer thinner, and or acetone when they demand a soak.. Zep sells a 5 gallon soak organisation that's the same as you call back. Though its not what it use to be, its yet the all-time that I accept constitute..

I too use the acetone with some gas mixed in to make information technology a petty more stable. The gas volition slow the evaporation downwardly a little.

i use a mix of stuff in a 1 gallon pigment cann . its a mix of lacquer thinner and carb spray it eats paint off and reall pulls the old gas out of the ports .just driblet in and allow information technology sit down
Now this is a good thread. Nifty info for someone who wants to learn the "old" guys tricks. Thank you!
I got mine from Advanced Auto. I forget the brand now simply its what you recalled. 1 gallon can with the metallic basket within. It works very well. I will get the name for you. I think its made by GUNK?:shrug:
Dichloromethane if you can find it.
Very unhealthy stuff.....
Xylene and fourth dimension are generaly effective for dipping
I bought gunk dip from the local A/P this stuff is a joke. its like wd40 non carb cleaner I had a carb in it for 3 weeks notwithstanding no amend than it was.
Try AutoZone they carry Berryman in the stores hither in North Westward Ohio. I selection this ane upward a couple of months ago. 19.99 each.

That old school cleaner was banned several years ago. Information technology truely was adept stuff, but very toxic. Im glad its gone. The new, safer stuff sucks, some is even water based. It takes a few days to accomplish what the old stuff did in a few hours. Nosotros have the five gallon pail from napa, its ok stuff.
Does anyone boil carbs anymore? Sounds crazy but before we stopped rebuilding carbs at the shop we saved quite a few by boiling them, especially when the piddling plunger on the tecumseh carbs wouldnt rattle, freed em right up.
I employ a combination of Minerial Spirits and Paint Thinner in a HF Ultrasonic Cleaner to practice my carbs. So far its worked real proficient.
After several days of soaking in the new carb cleaners and no results, we tried vinagar. Information technology freed upward the check brawl in a briggs fuel pick-up, should work for the tecumseh checkball too.
I bought one from Napa ( I get a discount in that location ) and it works good.
fourth dimension for another story. I was checking for a no estrus call on a Lennox gas furnace, and institute existent bad burners and the heat exchanger was full of gunk. I constitute sitting correct below the furnace a slightly open five gallon can of professional carb cleaner that had sent all the fumes from that fluid into the furnace fire chamber. The tin was almost empty the man of the house was a Ford Mechanic and said he idea it was airtight upwardly tight. It did 15 years of ageing to that furnace.

I never tried that.
Sounds like a very smart trick.
Going to throw out a thought now.
Perhaps a boil with a little washing soda to push the PH upwardly and help dislodge the varnish.
Since talking well-nigh boiling things.
I remember Gramps boiling former batteries to clean the plates in a big wash tub.
Then we would refill them with acrid and attempt and clasp a little more life out of them.
Point to my ramble is nosotros often forget how effective a little heat and water can exist to clena things.
I take had swell results using vinegar, but y'all need to degrease the part offset. I utilise laundry detergent and h2o to degrease, then ten-15 minutes in vinegar. Y'all have to then rinse and castor the parts with water to be certain to remove all traces of the vinegar or there will be spots of corrosion later. White vinegar is 5% acetic acid and is near $2.00 at the grocery store. The power of vinegar to remove varnish from old gas is impressive. The vinegar gets dingy later a few carb cleanings and then it tin can be used to remove rust on parts. I have soaked chains overnight that were rusted solid and they are very useable afterwards.

I have used vinegar on corroded carbs to clean them up , I heard that humid in vinegar works also. And yes it has to be cleaned off well because vinegar is a mild acid.
A like to have a five gal bucket of NAPA # Mac 6505 around, its just a full general parts cleaner read the msds some potant stuff.
I have been using "Engine Tune-up" spray for years. I learned near this stuff while working on outboards. OMC and Yamaha sell it. You can likewise get the same stuff from whatsoever general Motors dealer. The may call it "Acme Engine Cleaner" or something similar.
The solvent is designed to exist sprayed into a running engine to loosen carbon deposits and costless sticking piston rings and valves. Believe me, this stuff works! Half the functioning problems on onetime outboards is from sticking rings because of the common cold h2o cooling effect and two stroke oils.
Getting back to cleaning carbs, This stuff absolutely eats gum and varnish left from old fuel. Just hose everything down with this and wait a while before rinsing with gumout spray or contact cleaner.
So pick upward some mag wheel cleaner (the carving kind that is the strongest) and clean everything again, just utilise hot water to rinse off parts, and don't go out things soaking for more that a few minutes at a time. Repeat the wheel cleaner process as needed. accident out all the passages and jets.
Y'all volition now take a clean and shiny carburetor!

That "New" Chem dip is not the aforementioned equally the old stuff; the old Chem dip would have melted that plastic basket in a New York 2nd.
IF you go to United mexican states... yep y'all can get some of the old stuff, the real McCoy, will melt your socks off and besides melt the can information technology comes in (Also says Berryman on the can)!
As said Dichloromethane is practiced and nasty only hard to find and non available over the counter due to issues, but in United mexican states..
I used to repair printers years ago and we used a mixture of Benzene, acetone, 3608 Lacquer thinner and a 90% solution of Alcohol to make clean our printers with and found information technology worked well on carbs as well, we all had our ain idea of how we mixed it simply the Benzene, acetone and Lacquer thinner alone worked well 1/three each. Might add some gas or diesel fuel to boring down the evaporation though and keep it sealed in an airtight container all the time. Store it in the backyard!
Do non store this brew inside as it can spontaneous ignite on its own, rags and towels Take to be tending of in a sealed container as they WILL grab fire if left in the trash.
So not burn them in the BBQ as it makes the food gustatory modality funny (also toxic).
Just for the record hither, nearly engine cleaners that are aerosol are picayune more than then dishwashing liquid and diesel fuel mixed (and a foaming agent).
