    Guy brings over a holley 800 4780 that was nasty, absolutely caked with white junk and dried gas deposits. He just wanted it rebuilt, nothing fancy. I gave him my usual price of $50 plus the cost of the kit. He freaked and said other guys didn't want to touch it since it was so nasty. I laughed and told him all you have to do is take it apart and boil it in lemon juice.
    He didn't believe it so I told him to just come pick it up tomorrow and it'll be good as new.
    Carb came out and looked like new, I installed it and hardly had to tune it. Worked great. He tried to give me $300 and I told him keep your money and send me some referrals.
    Anyway, if you build your own carbs and stress over ugly ones, don't spend a bunch of money on carb cleaners and buckets of cleaners to dip them. Boil them for 30 minutes in 1/2 lemon juice and 1/2 water. Spray orafices with carb cleaner then blow it dry. It'll be good as new.

    You guys may already know all that, but it does work.

    I don't have a picture, it's on the guy's car. The reason I posted this is because it's a great, inexpensive method of cleaning carbs. Next one I do, I'll post before and after shots.

    Yeah that works too.
    Boiling with lemon juice creates an acid that cleans and simply eats away contaminants yet won't harm the carb finish.

    Where do you get enough lemon juice to drop a whole carb into? I dig the idea, but sounds like two qts of lemon juice is needed.

    Just found that wally mart has it in jugs. google answers everything. I keep an electric hot plate in the garage for this kind of thing. I will try it on some nasty motorcycle petcocks that I have. Carb cleaner wont budge the junk that is plugging these things.

    I just pick up some natural lemon juice from the grocery store, pour it in a pot and add enough water to cover the contents, like the main body, metering blocks, bowls etc.

    It really works. I usually use a lot more lemon juice than other guys but, in this case, too much won't hurt anything.
