Here is a question... I have a pump computer that is very nasty. This thing is really bad, and needs a good cleaning but I don't want to take the dials out. Anyone had good luck cleaning these as one piece? Maybe easy off oven cleaner, carburetor cleaner and not hurt the paint on the dials?

I put the computer in a old oildrain pan and use wd-40 , then let it soak , for a few hours , spray it a couple times , put the rod in the bottom and use visegrips to turn it one you git it free just use air to git all the crap off, and i use a lot of different size brushes ,

My friend has had excellent results by spraying a ton of WD-40 on the computer then turning back and forth by hand. None of the dials were harmed as far as I know. I have one stuck computer in a M&S 80 but haven't tried it yet myself.

Good Luck

Good old WD-40. Spray it down every few hours for a day or two. Try to rotate from the bottom or reset using the handle as you go.

Do this in a well ventilated area and wear goggles!!!

To CLEAN the computer, I use Simple Green Concentrate. I have a 5 gallon plastic oil drain bucket and keep about two gallons of straight strength SG in it( you can reuse by letting contaminants settle and pouring off usable liquid) I break the computer in half by unbolting the wheel mechanism from the bottom calibrating cannister. This is a simple process since one shaft connects the two. I soak both halves separately and clean with a small nylon brush. Then I pressure wash with hot soapy water. Then you can lubricate the mech to spin freely. The solution will cut the grease and will cut the old gasoline haze formed on the wheels and the metal. Also works well for cleaning gas haze off sight glasses. I live in town and have to keep the Fire Dept. happy using only non flammable and biodegradable solvents. If the # wheels are badly oxidized, they are going to wash off no matter what you try to clean with.

And..... if the number paint is coming off anyway, I take them to my friend and he soaks the really nasty ones in his radiator cleaning tank.
