25/4/11 Fouled Fuel Tanks Q. I am restoring a 1930 Fordson that stood for six years with gasoline in the tank. What does it take to remove the varnish from the tank and carburetor? Eugene Hickmann, 11915 Meeme Road, Newton, WI 53063.

A. We believe there are several things you can use, but all are hazardous materials and should be used with the greatest of care-preferably outdoors, and certainly away from any fire, naked light bulbs, or anything that might even create static electricity! Our personal preference is to use acetone. It can usually be purchased at fleet stores and paint stores. This stuff bites into almost anything but is extremely flammable and more than a little toxic. Then too, there are numerous carburetor cleaners, or you may prefer to take the tank and carburetor to an automotive machine shop and let them do a professional cleaning job. One thing is certain-any remaining varnish and other crud in the tank and carburetor will be a never ending source of trouble!

25/4/12 Witte Diesel Q. See the photo of my Witte Diesel, 12 hp, s/nD21010. Can you tell me the year of this engine, and whether any manuals might be available? What is the proper color? I have tried starting the engine but the compression is low and it will not start. Any information will be appreciated.
