  • Zenith carb cleaner

    I have one of my Zenith carbs in mineral spirits as of today. I bought a box of TSP and plan to boil it tomorrow for a few hours and then put it in the freezer for a spell. I will check out if brass comes out freely. I will clean ports out with a paper clip or wire suitable for that chore. My question is, is bead blasting that necessary ? I have a friend that could do it for me, but I need my extra arm and leg right now. pAAt

    I use Black Beauty from Menards to clean them up and remove the rust.

      Tom, I've been buying a lot of chemicals lately and there not cheap ! Black Beauty is on my list now, but, should I store all this stuff in a separate shelter away from my welder and cutting torch ? I'm thinking ahead for the big boom thing

    Like Tom i blast them in my cabinent then clean everything out with carb cleaner using a straw and compressed air. I don't think there is a single way to go about it as we all try and achieve the same end result

      Pat, Black Beauty is just ground up coal clinkers, so store it where it won't get wet, and mice won't chew through the bag. Inside a large plastic tub is ideal. Woodbury has a mountain of coal clinkers, and that's where the factory is. You can save about 50% if you buy them by the pallet. I should have done that years ago, but I'm not using too much right now.

        Normally I bake them at 450° for an hour, wrap them in a towel and put them in the freezer for 3 hours or more. This normally loosens up the crud and makes removing the jets much easier. Then soak in mineral spirits for a couple of days, then beadblast. As mentioned above get out all of the blasting media. Rod

          Rowdy, can I bead blast with my small sand blaster ? I have friend with a cabinet, but want to try this on my own. Thanks, Pat

          That depends alot with the nozzle and if your compressor will keep up. Do not use sand....... Please. Use glass beads or Black Beauty as Tom mentioned. One advantage of a cabinet is it recycles the media until it is dust, then vacumes it away. I regret selling mine. Will be buying a new one and a bigger compressor in the near future. You just can not do a good restoration without unless you pay someone else for use of theirs. Rod

        Submerging it in evaporust is another viable safe option.
        This will get into the passages also

          What I use for cleaning Zenith carb bodies is to immerse them in a container filled with 1 part molasses and 8 parts water , very inexpensive and 100% effective . Let soak for a couple of days and you will be amazed at the results . Remove and rinse with water , environmentally safe. To prevent flash rust coat with a Phosforic acid based product or paint after drying .I use this method for all my heavily rusted small parts.

          I follow the electrolytic process on to remove the rust and old paint. Works well!

            I found a 24 hour soak in Carb Cleaner in the gallon bucket, cleaned it well and got rid of 100% of the paint. Then I dried it and put it in Evaporust for 24 hours. Although I was able to get all the jets out before I did this. It was perfect ready for paint and reassembly with new jets.

              Parts cleaning...ultrasonic
              by Bikerider58
              In various threads folks have mentioned using an ultrasonic cleaner and evapo-rust has a demonstration on their site, so I just ordered a 3.0 liter volume unit with heater.

              Evapo-rust or rust 911 for iron rusty bits seems clear.

              What the best of ways to store a Zenith carb? Acquiring a second carb, it was rebuilt a few months back and the guy came in possession of a Marvel. Needs to sell the Zenith to help pay for the Marvel. I'm buying it.

              Carb Venturi Removal
              by WayneT
              I recently purchased a Zenith 1 carb advertised as overhauled. It ran terribly on my A so I took it apart and find that the venturi is frozen in place. "Les" says apply heat which I did to the carb body and with vise grips on the venturi it does not budge! ( I have a new venturi on order) I have NEVER seen a venturi that I could not remove without heat so this is a first for me.

              Which Carburetor to use?
              by benbuilder
              I am trying to get a project car running. I have it wired properly-with this forums help. I have oil in the tops of the pistons, i have turned the engine by hand. When i put gas in the temporary tank, It all leaked out of the carburetor.

              The carb on the car is a Marvel Schebler. Included in the sale was a Tillotson and a zenith. The zenith is missing a few pieces so no to that. ...

              Zenith Carburator modifiction
              by gdaquilina
              The Zenith Carb I just rebuilt had been modified by a previous owner who put a cover over the back area of the carb which included the vent. I'm thinking that this was to somehow control the temperature of the carb air balance system.
              Has anyone seen this before? Comments on the reason?? The vent air comes from the bottom of the carb now instead of from the top. ...

              Carburetor Suggestions Needed
              by Rumbleseater
              My newly acquired '29 Coupe is currently running the carb pictured. Problem is, it slowly seeps gas out of the intake. Gas shut-off valve inside is closed, and the GAV turned all the way shut (lightly). The car has to run with the GAV one turn open all the time, cold & hot. The car came with what appears to be a completely rebuilt Zenith carb. Inside is clean and all passages are open. Checked...

              Where to buy a Zenith B carb
              by Thosd
              I have not been able to source a Zenith B carb for my A. All I seem to find are rusted, pitted bowls on E bay. How does one obtain a complete B carb? I'm not adverse to rebuilding a salvageable carb.

              Model B carb. rebuild
              by Mickey
              Can anyone (would anyone) build me a good working B carb. from what you see here? I would ,of course, pay for any additional materials. The first three shots are the same table, different view. The fourth shot is three additional cores. I've checked most of the best vendors and other sources. None. Renner no longer rebuilds carbs....

              Will Seafoam clean a carb, or more accurately keep it clean, after the car has been sitting for awhile? I don't drive my widebed very often, and the Weber carb often has plugged accelerator pump action. It is a chore for me to remove the carb and clean the passageways. TIA, Jim B
