Forgive me because I have seen this on here before, but my search doesn’t find it. What cleaner is used to soak a carb in that really cleans them up? My WD is in need of a good cleaning inside. Vinegar? ------------- 1968 B-208, 1976 720 (2 of them)Danco brush hog, single bottom plow,52" snow thrower, belly mower,rear tine tiller, rear blade, front blade, 57"sickle bar,1983 917 hydro, 1968 7hp sno-bee, 1968 190XTD |

| Buy Gum Out carb cleaner. You can buy it in a spray can at Wal Mart. Does a great job of cleaning. Spray the entire interior surface and let it soak for about 10 minutes. Rinse out with another small amount of spray and brush and wipe clean. Should look like new when finished. You might be able to purchase the spray in a pint or quart container so you can pour some in the bowl and brush with a round stiff bristle brush to clean. |

I know the thread you're looking for. I had suggested Berryman Chem-dip, comes in a steel paint can with a dip basket inside. Soak for a couple hours brush lightly and rinse with water, takes off paint and all though so you have to prime it fast or it will rust. I like the soaking cleaners better than spray, even better you can soak then spray afterward. ------------- 1951 WD #78283, 1918 Case 28x50 Thresher #76738, Case Centennial B 2x16 Plow |

Bill's suggestion is spot on. I bought a can of Chem-Dip a couple years ago, and it works wonders. An older veteran told me in the army they used to boil carburetors in water for a few hours. I tried it and that worked with great results. Only caution...do it outside with plenty of ventilation and use bottled water if you tap water is hard...I didn't think about that and it made the pieces all chalky. Boiled again in soft water and that cleaned it up better. I've also heard you can add lemon juice or vinegar to the water and that'll help speed things up a bit.

I've only ever used the spray carb cleaner (Gum Out has served me well) but I've had to take the same carb apart 2 or 3 times to get it properly cleaned and set with that method. Never tried the dip, but I hear good things. Last time I had issues, instead of spraying it clean, I used compressed air and it blew all the crud out of my main jet that was giving me fits. Tractor has been running good for about 4 years since then. |

I think that’s the thread. Not sure why I could not find it. Thank you very much. I had heard vinegar but not lemon juice. I have some of the chem-clean also. Thanks everyone for your tips. I will let you know how I get along. ------------- 1968 B-208, 1976 720 (2 of them)Danco brush hog, single bottom plow,52" snow thrower, belly mower,rear tine tiller, rear blade, front blade, 57"sickle bar,1983 917 hydro, 1968 7hp sno-bee, 1968 190XTD |

Dick L has posted years back about boiling them in water and (I THINK) dawn dish soap. I'll go see if I can find that post... ------------- "Allis-Express" 19?? WC / 1941 C / 1952 CA / 1956 WD45 / 1957 WD45 / 1958 D-17 |

I use Purple Power in my sonic cleaner. Let it buzz for a few minutes, pull it out and rinse/scrub a bit and they usually are very clean. I remove everything I can before doing it. ------------- Charlie '48 B, '51 CA, '56 WD45 '61 D17, '63 D12, '65 D10 , '68 One-Ninety XTD |

| I left a carburetor in that chem-dip for 4 months once. I didn't mean too, I just got caught up in other things and didn't get back to it. I didn't think it would cause any harm though. It didn't seem to effect the steel and brass pieces, but you could tell it eat away at the venturi. I used the carb anyway and the tractor ran fine, but I never could get it to stop leaking. I'm not sure if that's the reason or not, maybe it eat out some of the passages to big. I'm going to try the carb again at some point. I do believe the chem-dip is your best bet, then some spray cleaner afterwards. Just don't leave it to long. I think that would get one as clean as I could get it anyway, maybe professionals can do better. |

| When I used to work in a garage back in the 70s we had a carb cleaner it was a heated ultrasonic machine with chem dip in it. 1/2 hour and the carb was spotless. I used chem dip army house with nearly as good results just took a lot longer. Drop it in at night and it was ready the next morning. You can do several carbs before it loses its effictiveness. |

Almost two years ago my 170 tractor motor started cutting out as soon I opened the throttle above idle speed. I had good spark from the ignition system so my attention turned to the carb. It acted just like my old Harley when the high speed jet plugged up. I was preparing to remove the carb but decided to try a couple of rounds of cleaner, GumOut and SeaFoam. I had a pretty strong mix in the gas tank, operated the tractor for about an hour (at low engine speed of course) then parked the tractor in the shed for about a week. As I backed it out I noticed a little improvement and after about 30 minutes the motor returned to normal operation. I was certainly happy about the outcome. I keep SeaFoam on hand to treat the gas once in a while.

I have had very good results with the Berryman Carb Dip. If you overhaul a John Deere Johnny popper carburetor, there are brass plugs which MUST be removed. Carb dip and sprays will NOT get them clean. These hidden passages require various size bits to clean them. NEVER use a power drill on a drill bit when cleaning out a carb passage. It is not good to oversize passages. SeaFoam is good stuff and will dissolve gunk and carbon. If storing and engine, put some Sta-bil in the fuel. Follow directions on label. |

Seafoam is my go to product on a running machine. It is an unbelievable product and cleans engine parts very well. However, in this case, I am cleaning a non running WD carb that is really gummed up. Once its cleaned, Seafoam will be a normal product to keep it that way. I am soaking it in B-12. So far its really cutting the grim, by tomorrow it hopefully will be clean. ------------- 1968 B-208, 1976 720 (2 of them)Danco brush hog, single bottom plow,52" snow thrower, belly mower,rear tine tiller, rear blade, front blade, 57"sickle bar,1983 917 hydro, 1968 7hp sno-bee, 1968 190XTD |

Chem-dip tank for two nights, then Vinegar and water in an ultrasonic hot-tank... for an hour. Then rinse with fresh water. Probe each passageway (my favorite is a .009" guitar string (high E, stainless... D'Addario, well used, cut into 6" segments, with one end lightly hammered, the other left smooth) then blow out with compressed air. ------------- Ten Amendments, Ten Commandments, and one Golden Rule solve most every problem. Citrus hand-cleaner with Pumice does the rest. |

Very funny!!! I remember when the band released that great old song. Heck, The Rolling Stones convinced me to play Rock music on my electric guitar. "Satisfaction " was a game changer for me. Man that was a long time ago.......
