|I bought the my Humdinger "mudpump" unit as a sort of last minute purchase at the Waukee swap meet in 1987.
It is powered by a 1923 1 1/2 hp Fairbanks Morse throttle governed engine. Made by Ralph B. Carter Company of N.Y.,
N.Y., it was all original, including the starter crank, and spanner for the hoses!
I took it home, sprayed the magneto down good with WD40 so the armature would move and proceeded to loosen up other parts as needed. Boy, was this thing greasy and sticky! The magneto was so loaded with grease and gum, you could turn the armature back as if to trip it, and it would stay put. In fact, the only reason this engine wasn't stuck is that water couldn't have possibly gotten to most parts for the grease and cement dust on it. Within 30 minutes of unloading, and nearly a can of WD40 later, I had it running. It was missing only the covers for the intake and outlet valves on the pump, which I easily made from flat steel using a torch, grinder, and drill press. I ran it at shows for several years with no means of displaying how the pump worked - running it just to watch the pump go up and down. Finally, I got some 3" fittings and suction hose (let me tell you, those were NOT cheap!) and using an old oil barrel with top cut out, soon had it pumping water. The original diaphragm was weathered, but still functioned. In 1996 at the summer show at Waukee, it finally happened, that old diaphragm developed a leak big enough to shoot a bit of water skyward on each stroke. After a long search, and $125 later, I had a brand new diaphragm. About that time, Barbara asks why I haven't "cleaned it up" and restored it as I've done several others. She also hated that old steel oil barrel, which was starting to look rusty. I didn't have a good excuse, and opinion was running about 50-50 as to if I should restore it, or show it as is. She made the decision for me, saying that I "wasn't taking it with me again until it was all cleaned up and properly restored as it looked like heck".
The rest is told in the picture story below. I had to scrape years of hardened grease, compounded by the fact that it was mixed with cement dust and gravel, just to get to the bolts and nuts! After hours of scraping, pressure washing, several cans of oven cleaner (it works well), soaking in solvent, most parts spending a couple of hours in my electrolysis bucket, and finally, sandblasting the larger parts, it was ready...........................
