This model was machined and built from a casting kit. Many hours of machine work and assembly goes into producing a quality scale model like this. A lathe, milling machine and experienced operator were needed to finish the castings and to fabricate the additional parts required. Having to pay someone for all of the machine work and fabrication involved would cost quite a bit! A word about the photos… On my computer screen the color of the engine looks a bit brighter red than it actually is. That photo shows the actual color a bit better. The scale of this engine…. My 1/2 scale Olds has flywheels that are just under 8 inches. A couple of the 1/4 scale engines I have, have flywheels that measure in the 4 1/2 inch range and they weigh in at less than half of the 29 pounds that this one weighs. The information I found on the casting kit that this one was machined from did not list the scale of the kit. I did find a few casting kits of other makes of engines that were made in both 1/4 and 1/2 scale like the Olds. Of course that completely depends on the size of the real thing. I might not be correct as I do not have a full scale one in front of me to measure so I felt it best to point this out as I don’t want to list the wrong information in my ad. The size and weight information is in this ad. I show a Coke can in some of the photos for a size reference. I will leave it up to you as to what scale you think it is. Not including the wooden display stand this engine measures 10 3/4 inches tall (to the top of the exhaust stack). From the back of the flywheel to the tip of the exhaust rocker arm it’s 14 inches long. And from the outside edges of the flywheels it’s 7 inches wide. The wooden box it is mounted to measures 14 x 7 x 3 inches. Total height to the top of the exhaust stack including the 3 inch base is 13 ¾ inches. It weighs in at slightly under 30 lbs. Specifications on the kit this was machines from; Flywheels – 7.625 inch Bore – 1.5 inch Stroke – 2.530 inch. Ignition is provided by a antique buzz coil that is mounted under the display/running box. (shown in a photo above) There are two connections mounted on the box for electrical hook up to the buzz coil. (you only need to use one of them) One is a RCA jack (I believe that is set up for the center to be negative) and the other is two brass bolt studs for clipping on alligator clips. I used a 12 volt jell-cell battery (not included) to power the coil. This engine started up for me on the 3. Try after sitting for many years. As you can see in the video, it runs great! Here is a web link that will take you to the video of this engine running. “1/2 scale model Perkins Hit and Miss Engine” My YouTube user name is JoeKind1958. Not my real name. The fuel I use is Coleman lantern fuel with some model engine Castor oil mixed in at around 40:1. Two cycle mix will work as well. It will run on run on regular pump gas but I would not recommend it due to the methanol and corrosive additives that are now added to our once good gasoline. There is a oil cup for cylinder lubrication. 10-30wt oil works fine for that and lubricating any other moving parts. There are 3 grease cups. Turn in these cups before each time you run this engine. Turn in the cups till you see some grease coming out of the moving joint. They don’t need to be turned in all the way till they are tight. When they do get tight when turned in, then it’s time to add more bearing grease to the cups. On the fuel mixture setting. I ran it at about only ¼ turn out. When turning the fuel mixture screw in all the way to make a adjustment, just turn it in till the needle touches it’s seat. Don’t make it tight as this will damage the needle or seat. NOTE: This is a running reproduction of a antique engine. It is a adult collectable item and is intended to be used by a experienced adult. Just like the original engine, it has no safety guards in place. The bottom of the connecting rod does stick out past the back of the block when it is turned over by hand or it’s running. Loose clothing, long hair or fingers could become cough in the bottom of the connecting rod/crankshaft or any moving part when this engine is running. Simply use common sense and keep your fingers especially small fingers! Away from all moving parts! I make no guarantee on how this will run for you. You should have some mechanical experience with small engines to get this to run properly. ALL SALES ARE FINAL! As you can see there is a lot of room for protective packing material and another box if I decide to double box it. I will not be packing this up till the sale is final and it has been paid for. This is a running, gasoline powered scale model engine that comes with no instructions or guarantees what so ever!! Do not stick your finger or other body parts in a rotating mechanical assembly!! The new owner assumes all responsibilities and liabilities to himself/herself and others with this engine. This is an “adult collectible” item not to be operated or played with by children. I make no clams to it being safe as it is a antique scale model reproduction produced back in the day when no safety guards, air bags, safety warning labels, ect.. Were attached to dangerous products. I make no claims that it will even run as some might not have the mechanical ability to figure it out. Could you even imagine the 1,000 page, government regulated, congress approved (if they could agree on it) safety book that would have to be included with a Hit & Miss motor? If this were to have a modern consumer warning attached to it, it would probably advise you to wear fireproof clothing, protective boots and gloves, wear eye protection (although eye protection is a good idea) , a helmet and some sort of respirator. Wrap yourself in organic bubble wrap, mark the running site with cones and protective tape that is specified on page 885. God this country is driving me nuts!!
