very dirty carb
I know this may be in the wrong place as it is not a Ford product, but it is more of a general carb question anyway. I opened up the carb on my boat yesterday to find that the float bowl was filled with a white powdery substance (looked alot like the corrosion on a battery terminal). The motor was left uncovered for several months in the rain. The carb in its current condition is very unusable....could anyone tell me what this stuff is or how to clean it? Also, if anyone could point me in the direction of a good boating forum that would be much appreciated as I'm sure that this will not be my only problem.
Thanks

I don't know of any good boating forums, but the white stuff I think is corrosion from white metal which is the carb unit and water, which makes the white stuff. I have never found a chemical out there that does a good job in removing the white stuff either, the last carb that I did, I did have some white crap if I recall, but I also have an ultrasonic cleaning tank, put the carb in it with water in the tank and turned it on, Water does a nice job, can be a good cleaner, but it does not remove all of the white coloring. I don't know that I would worry to much about the corrosion that it has created as long as you can get the inside clean enough and there is no floaters left inside to clog up jets and air pipes. Try gasoline as a cleaner with a flux brush or a good stiff brush or send it to me with a kit and I will strip it down and put it in my ultrasonic tank and give it a try for you, Cost will be shipping. What kind of engine is this carb on?

The carb is a rochester 2 barrel on a 140 mercruiser. I have decided to soak the whole carb in a bucket of carb cleaner or gasoline. I might also try a solution of muriatic acid. I know I can clean the stuff out of the bowl and from around the float but the small passages worry me. Before I took it apart, the stuff was so bad that the accelerator pump would not budge.

That's in there pretty good, FYI, the ultrasonic tank is like having 10 million small hammers beating the hard surface from every direction at the same time, even inside where you cannot get at, all of the small passages, but when you try to clean the passages, get a can of carb cleaner with the small nozzle and shoot into the tubes and holes, make sure it ends out somewhere else than where you shoot it in at. I'll ask my friend tomorrow about a chemical you can soak it in, he has a masters degree in chemistry, I will report. Broken wire

I asked my friend, he did not know what to tell you to use, except for that it remove Aluminium Oxide, so maybe if you do a search on the net, you may find a good product to break that white fluff down. Before using the muratic, you may want to try vinegar. Just alot more milder than Muratic to start off with. Broken wire
