This page is an e-mail I rec'd from a fellow Associated engine owner that has a water cooled Iowa Oversize Chore Boy with the fuel tank in the base, just like my air-cooled Chore Boy.  I thought the discussion was filled with good info so I decided to make key-words into clickable links and share the information so that if there are other "fuel tank in the base" engine owners out there, (And I have a feeling that there are more than we realise) maybe this forum will help you to restore your engine back to original.  Hope this proves helpful.  I have put both messages together so as to not confuse the reader.

Dick: Hi Keith--Very interesting story, and it raises a few more questions: About your Chore Boy with the tank in the base: 1 What is the  serial number?

Keith: 1. the serial number is 33855 which makes the year of manufacture approximately 1917, but with a straight trip. This info may lead to either the theory that chore boy engines are found with the goose neck style trips starting later than late 1916 because of an existing stock of straight trips at the factory, or my serial number guide needs adjusted just a bit to move this engine back to late 1916 instead of the April/May 1917 that I currently decipher the serial number to be.

Dick: 2. Is it mounted on skids or on a cart?

Keith: 2. I found this engine mounted on non-original skids. Weather on a cart or not, this engine from the Associated factory should have been mounted on a 2" x 12" x 48" slab.

Dick: 3. Is the notch you mentioned in the bottom, perhaps to accommodate a fuel line? Cut with a grinder?

Keith: 3. The notch or notches are 1. in the same location as yours in the crank guard and 2 in the sub-base rim with the additional hole for a bracket to stabilize the filler tube. It looks as though the notch in the crank guard is factory cut and the notch in the sub-base is cast that way, not cut with a grinder.

Dick: 4. Can you send any pictures of it, especially showing fuel line routing? Since my serial number comes after the start of Iowa Over Size (which I assume all had tank in base) I wonder if this wasn't somebody"s idea to use up all the old castings that didn't have the required holes for fuel entry and exit in them?  My casting had four holes drilled in the bottom for screws to mount the tank.  There is an additional hole drilled in the top face for a small bracket, slipped over the filler pipe to be attached to stabilize the filler pipe. There is in relief cut in the bottom to allow a fuel line.

Keith: There is no notch in the bottom of the base for the fuel line to come out to the mixer, but a notch may have been made in the wood to accommodate. There are also the 4 small holes in the base for the 2 brackets to secure the tank in the base. Interestingly enough, my 2 1/4HP Hired Hand also has these 4 holes in the base for the fuel tank mounting and a notch in the crank guard but no notch in the sub-base for the filler tube, though there is a hole drilled that must be for the bracket to stabilize the filler tube, like yours is set up. The Chore Boy & Hired Man/Hand share the same sub-base, just a different bore size and different weight flywheels. My Hired Hand originally powered a Niagara Orchard sprayer so I guess the fuel tank in the base was probably because of the lack of space on the sprayer rig.

Dick: Can you tell from the picture if my cart looks to be an Associated cart? It looks like one, but the numbers cast on the grab handles (T099) match Bud Wilson's nice original Rock Island cart and engine.

Keith: The slab your engine is on looks to be correct, though the cart does not look to be. Associated wheels had round spokes, not cast into the wheel (see pics of a 3HP on original cart)

Dick: In the light of what you have told me I plan to go back to my original tank, and will probably cut 2 new 44 or 48" skids for the cart so the fuel line can get thru. Best regards, Dick

Keith: My air cooled Chore boy is in the process of being re-built, so I do not have a good pic of it with the correct fuel line routing. But I am glad to get all this straight before hand so it will be put back the way it is supposed to be. It is also good to talk to some one with another engine with the fuel tank in the base. I have hundreds of pics of Associated engines, but none with a fuel tank in the base like mine! When I got this engine it was totally covered with grease and grit, upon removal of this stuff, I have found 85% of the original paint intact including the silver paint on the cylinder, which is amazing that it never got burnt off. I am missing the mixer and I need new rings, but I hope to get it all back together this winter for next year's show season.
