Old crusty carburetors: what should I soak them in?!?

    I've got some oooooold holley carbs I got for free, one is from a '58 Edsel(thanks for helping me decode it!) 750 vacuum secondary that would actually be nice to use if I can rebuild it. Other is a 600 vacuum secondary.

    What should I soak these in? Is there any trick to removing these screws? The last time I rebuilt a carb eons ago I broke a float post trying to chisel the needle seat out of it and never got it totally broken down because I couldn't get all the bolts out.

    So! Is there a solution besides carb cleaner I can use to soak it in(molasses or something?) to clean it up after it's disassembled, and any suggestion on removing tough bolts? I think last time I also used an impact driver, which I don't recommend.

    Thanks in advance!

    They sell a bucket 3 gal size I think it call carb medic. Has a basket in it for straining parts. I got at my local parts store. The new stuff is not as potent has the stuff 20 years back. but its ok. I have used diesel fuel also. Then I hit them with the soda blaster.

    Give me your address and I'll send you a Holley booklet for free. It tells you how to rebuild them.You will need to buy a rebuild kit- As you must use New gaskets. It will leak if you don't.
    To remove the float bowl screws( four of them,each side,eight all together)) Attach a pair of vice grips to a flat blade screw driver handle and turn it like you mean it! Push in and round. It will give you the added leverage to get the screws out.
    Now, for your carb cleaner- Use carb cleaner from Walmart. Comes in a blue can with a red nozzle sprayer. Spray vigourously.
    When you re-install the cross-over pipe,be sure to put new o-rings. use a petroleum jelly to make sure they slide all the way back to the stop flange...
    I can send you the carb booklet anytime you send me your address.

    use the atf homemade penetrating oil to get it apart, then boil the parts in a pot of water and Tide on the stove, works like a charm...

    HA HA, My experience with Holley carbs says about 20 feet of river water.:D I've heard the ATF from several old timers though.

    I'd use some Kroil or other good penetrating oil to get things loose. Soak them with carb cleaner and then get out the hot water & soap.

    The ATF and mineral spirits both penetrates for dis-assembly and cleans.

    DO NOT use molassas or Vinegar (ask me how I know) unless you want the carb ro crumble in your hands.

    An ultrasonic cleaner with clear water will work better than any of the methods proposed so far. Adding a good biodegradable dish water detergent (I use Dawn) will improve the cleaning. Dunk the entire unit. The ultrasonic really helps to loosen stuck screws as well.

    And, there are some better detergents than Dawn for really crusty units, but none work as well without the ultrasonic as the ultrasonic and plain tap water.

  16. There are 2 types of Berrymans carb cleaner (in the gallon size) that are available. One, (B-12) for the States that have banned the REAL old time carb cleaners, and the other (B-9) which is still available in a few, Texas being one of them...which is where I get mine Shipped from. You might as well soak your carbs in water, as to use the B-12...it's useless. However, the B-9 is the real deal. 12 hours in it, and the carb comes out brand new clean. It will NOT remove corrosion, but it will remove EVERYthing but...

    man I'm tottally guilty of not searching the forum

    I was thinking specifically about the latest threads concerning molasses and vinegar and whatnot, thinking maybe one of them may or may not be good

    I tell you what, that ultrasonic stuff looks great. If the horrible freight can get me one at least soon, I'll give it a try. I read you don't have to be able to submerge the entire part, you can do it a bit at a time, so just in case the body of the carb won't fit in there

    looks to be around $70 or 80 for the size that appears useable.

    Heck I'll use it to clean other stuff like alternator cases and whatnot if it works like it appears, and chemicals are so expensive and weak anyway.

    I'll look for varsol at the hardware store, I used that in the oill field back in the day and it cleaned crud off tools like nothing. I'd be surprised they sell it, but who knows

    Thanks for the pine sol thread, I'm going to check it out in a minute :)

    Boil it in water. All the way in, everything! I have used it for every carb that was in the shop, car or motorcycle.

    Just a few days ago , I ve clean one using soda blasting like on the aircooled Vw website .
    I works great .
    The iron base had rust , and the soda doesn t remove it .
    So I used sugar ...
    I don t like the idea of sand in a carb :)
    Of course , it still need to be dipped to clean the internal .

    Expensive tools :

    B-12 has never worked for me, on motorcycle or car carbs. I use either Gumout or CRC's cleaner. I had a 5 gallon pail of Industrial carb dip, but stanky ass diesel has always worked. I use aluminum oxide on the less complex carbs as far as cleaning via media. I have small tools used to clean all passages of media.

    X2 on the soda blasting. Cleans it up like new and does not hurt the aluminum. I used a small gun like the pic above on a Edelbrock and it came out looking new.

    Well I disassembled that sucker and I've been using the ultrasonic cleaner..so far nothing too amazing, but I haven't given it enough time I don't think. I'll try again tomorrow when I won't bother anybody with noise :)

    I wonder if one of those rock/parts polishers would work. Attach a container with cleaner and carburetor to the lid, or down inside, and turn it on. Those things get to vibrating pretty well. Might try it for the fun of it.

    OK so I fooled with the ultrasonic deal today. Tried different soap, different amounts of parts in there, spacing them differently. For the noise, cost, hassle, small size, that I have to keep turning it back on every 8 minutes, I wasn't impressed.

    I bought a 6 gallon crockpot for $25 from wal mart. I have everything but the float bowls in there, they're already pretty clean plus I couldn't fit them so here goes nothign.

    Good will wanted $22 for an ancient used one so I was like forget it, I'll get it from wally world. A used crockpot should be like 6 bucks. Jeez.

    I've seen guys bungee cording an electric orbital sander to the side of a bucket to agitate. It's not ultrasonic, because that's a certain megahertz or something like that, and unfortunately I didn't see a follow up post.

    I was informed by mom there's a difference between a pressure cooker and a crock pot. Well, here goes nothin!! heh I'll keep you posted!

    edit: Not that anyone asked, but I gotta say this holley has been much easier to disasssemble etc than the q jets I rebuilt 20 years ago . It seems real simple to understand and now I get it wwhy they say its' for tinkerers, there's a *lot* of things to fool with.

    I don't have a clue how to tune it, but I have some books, what could go wrong?!? ;-)
     
  30. Yuh know, for about $30 you could have a gallon of the real thing carb cleaner delivered to your door...
