    If just your floats are sticking, you only need to clean them. I use a Q-tip with a bit of 0000 steel wool wrapped around the end. (take the cotton off first) Then twirl it a few times with you fingers and remove. Then use the other end with either Brasso or toothpaste to polish the seat in the same manner. Make sure the spring button on the end of the needle will compress and release, and put it back together.

    Whatever you do only use Vinegar cold.Never boil the carbs in it as it's an acid.

    "Never only ever" is a complex double negitive meaning "always" ... therefore, it reads

    I understand that vinegar is an acid.

    I also understand that aluminum is not inert, which means it is susceptible to acids and such.

    What I do not understand is why boiling it makes it any worse than just soaking it.

    I have seen on other forums they advise that you should boil it in vinegar.

    I am not saying anyone is right or wrong I am saying I am not a metallurgist and do not understand the reason it is different.



    Can anyone help out?



    So can I soak it in vinegar overnight with a home made agitator like TeacherTim used? Basically a random orbital sander mounted (on the tank holding the carbs)in some way so it does not fall in and short out.

    Is over night too long? Can I heat it but not boil it?



    I am not convinced my carbs are right or my ignition is right quite yet. Somebody is unhappy but I am not sure who so I want to strip the carbs again and this time soak them in vinegar.

    Raising the temperature accelerates the reaction of the vinegar to the calcium build up. I have boiled some at a 50/50 mix and had no problems. I probably let them boil for 15 minutes and then flushed with cold water.



    I routinely clean our faucet aerators from the hard water build up by putting a half cup of vinegar in the micro and bringing it to a boil, then drop in the aerator. Otherwise it takes forever to clean them. Or use CLR. It is a acid, not sure which one, probably HCL.

    I soaked a set for about a week in vinegar once,,don't soak the accelerator pump if you have one though. See this thread I started at the old forum.



    Rinse the carbs with water as soon as you bring them out of the vinegar.



    As for boiling I don't know,,there was a guy that slow boiled a set once and if I remember correctly they boiled dry and were left that way overnight or something,,they were not pretty when he got back to them.

    Well, its all based on physics.



    The acid (vinigar is very weak acetic acid) will react with compounds (calcium residue which is a carbonate) and break them down to form water and a soulble product (thus seeming to desolve it). The acid will ALSO react with many metals to form an oxide and sometimes a salt of the metal. So, whats temp got to do with it ... simple.... virtually ALL chemical reactions will proceed at a speed based on temperature. Boiling the vinagar will do two things for you



    1 - increase the reaction time thus making metal errosion move faster

    2 - remove water from the solution, thus increasing the acid concentration which speeds the reaction more.



    One small note about vinigar and boiling. Vinagar is WEAK acetic acid (about 4%) and tastey when put on fries. it is also the main ingredient of "wart remover" (about 30%). Pure acetic acid (98%) will blister your skin in about 5 seconds of contact. So while its mild household stuff, remember ALL acids can really wreck bike bits if not understood and used properly.



    (Also, your carbs are made from "aluminum alloy" NOT pure aluminum, and therefore some "parts" of the alloy will errode fasted based on their properties. Boiling can make nice microscopic pitting which can really degrade passageways and provide "biting surfaces" for fuel gum to latch on)
