carb rust Getting ready to strip my zenith and ultrasonic clean it. Is there a coating to use on the inside to prevent future rust problems. Seems to be a lot of rust removal and converters, but not sure about using inside of a carb. Also be compatible with all the brass jets and fuel.

Re: carb rust I flush with carb cleaner, maybe follow with wd40.
I now include a static test for cracks in the castings. |
Re: carb rust Aircraft Spruce have coating for the insides of gas tanks that may work inside a carburetor.

Re: carb rust Glyptol would be my choice.
Red, somewhat heavy coating impervious to oil, water, gasoline. Applied as a spray (thinner and more precise coating) or with a brush (heavier.) You'll want to mask well those areas you don't want to gamble to "plug." Used a lot on cast machine cases to prevent ingrained foundry sand from coming loose and getting into the moving parts. A bit expensive. About $55 for either 12oz spray can or 32oz brush on. Quality though... Joe K |
Re: carb rust Got the carb halves cooking in the sonic cleaner, going to check out some Butyrate Dope, just want to coat the bowl area where moisture seems to collect the most. Looks like the best bang for the buck. They are pretty proud of these fuel proof coatings $$$. Thanx for the quick response.

Re: carb rust Years ago I machined gun parts for Wilson Combat and at the time they done platting on new and old parts and older guns called metalaloy. Not for sure about the spelling. It was a stainless finish that would not come off and you could plate a gun and all of the parts including the screws and it didn't affect the reassembly at all. It was real pliable if the gun part got distorted it stayed on. Metalloy finish was harder and better on a gun than a solid stainless steel gun that was softer steel. If a zenith carb was Metalloy finished it would never wear out or rust any place on it or in it. I don't know where this could be done at anymore but I'm sure someone does it .

Re: carb rust I think the original Metalloy company is out of business. There are other companies that do other types of plating on gun parts. One type of plating may work for a carburetor. A gold plated carburetor would be interesting.

Re: carb rust Been getting small amount of rust in the bowl. Thought maybe I could eliminate a problem with a simple coating. Maybe WD-40 would be the ticket, drain the bowl and give it a squirt or two in the winter. Also add a bit of fuel dryer in the fall.
Got a pencil filter in the tank and haven't seen any rust particles in the filter bowl on the firewall. |
Re: carb rust Rust could be coming from gas tank, although gas is filtered.try a magnet in the sediment bowl if it is glass.
|
Re: carb rust I agree with some here - don't coat it with anything. How many decades were they run with NO coating without problems.

Re: carb rust I just had my Zenith carburetor apart, it’s been 5 years since I’ve had it off, the bowl metal is still shiny, it had some ( very little amount 1/4 of a thumble ) reddish brown rust dust floating on the bottom. Most of the time I put 4oz of MMO in a full tank of ethanol free gasoline unless I’am away from home needing fuel.

Re: carb rust I agree with others don't put anything in there. You're just asking for trouble if it comes loose. The light amount of surface rust that could come from the bowl is going to be very fine and unless something disturbs it it's just going to grow and be stuck there. It's not going to continuously shed particles that will be plugging jets. Other than the lousy ethanol, which is hydroscopic, there are rust inhibitors in most fuels, gasoline is an oil derivative, so it is an anticorrosion in itself. If you're putting something on the shelf for long-term, you can wipe with your finger some 3in1 oil around the bottom of the bowl if you're concerned. ��
