Picked up this little engine today at Mystic, NICE SHOW!!!! Did not see any markings on it and it is only 13.5" tall. Would this have been a school or shop built engine? or if you recognize it as from a particular manufacturer please let me know. It has good compression, so I assume it will be reasonably easy to get running....by the dust and grime on it....it has not been run in quite some time, I just oiled it up to help it along. ALSO can these type engines be run with modern day oils......say like the oil made for my STIHL chain saw?? Thanks "E" |

It's an early engine based on where the engine mount is located. Later engines had the mount at the centre line of the crankshaft. That allowed the engine to sit lower in the boat hull.
I reckon it would be in the 2 HP range.
As for oil - better to use a non-detergent SAE 40 motor oil. I use a 25:1 to 30:1 mix in my engines.
It might smoke a bit but the lubrication is needed.
Make sure the grease cups are clean and - USE them. The grease provides the seal for the crankcase. There are no crankcase oil seals on these early engines.
You'll need a buzz coil for the ignition. The one JB put together using an automotive relay is good (and cheap) and works off a 12 V battery. I can send you a diagram , if you'd like.
Some more pictures of the other side might help to ID it.

Miro, Thanks for your input. When I saw it I liked the base.....It was more like the farm engines I have collected and was not on the centerline of the crankcase. I assumed this meant it was an earlier engine, that and the fact that the castings are a bit on the crude side, and not cleanly machined everywhere. Has good compression, so I don't think it will take much to get it running. The former owner mentioned to me that he thought the piston may be in wrong (backwards) as when looking down at it...the "damn" is positioned more towards the exhaust port side than the intake side. I will have to try to start it to see if it wants to go or if there will be issues with that. In its currant position...the side on the intake port is somewhat "ramped up" or scouped to make the incoming fuel/air charge travel upward easier which would make sense to me...and the exhaust side is flat at a 90degree angle to the port. I will try to post more pics. The Carb is probably not made by the same builder...seams it has a nicer finish and is much finer quality...at least it seams it. AND it has a P T reducer installed to connect it to the crankcase |

This is a video of the engine. It was easier than posting pics Thanks "E"

Nice find! I also went to the Mystic show for the fist time yesterday, was great to see all the old engines and talk with the owners. I'm on the hunt for my first engine. I was hoping to buy something yesterday but I didn't see anything for sale.
Unsure if the pistol is backwards or not, i'm sure some of the more experienced here can confirm that. I do know that in the Upright maytags I collect the piston has a similar arch at the top and it does matter what way it points, so if you see things aren't running right that might be the first thing to consider reversing.
Be sure to share a video once you get it running. |

It looks like your piston is installed backwards .
The idea is that the incoming gas hits the wall of the dam which is near the inlet port and goes upwards.
Your engine might fire once or twice but it probably won't run well until you get the piston turned around.
You'll also find that the mixing valve ( instead of a carb) is quite sensitive to how far above it, is the gas tank. |

Hello, I started it today, just for a short run to see if it would ...in fact...run. It did , but not great, May change the piston around and put a check valve in the fuel line...then..I should be able to put the fuel tank below the carb..........at least that's how it works on my other engines. |

Oops, Forgot...THANK YOU for your input.....I think it might very well run better with the piston turned around. What is your opinion on weather it was a production engine, or maybe a shop built or blacksmith built one off design? Thanks again !! |

Hello Enginesilo, Mystic is a nice show, however really nothing for sale other than in the swap building....was slim pickins in there I thought...other than this engine. I was told by another collector it had been for sale for a couple of years. You can probably buy a running marine engine for what I paid for it...and it is gonna need some work, but, I just REALLY liked it. In looking at it more...I doubt it is an engine that was produced by a manufacturer, its probably more likely a school project or blacksmith engine. May never know for sure, but the design indicates an earlier school of thought in the mounting base anyway. |

Thanks Scott, still have to pull it apart and reverse piston...and set up a cooling tank and fuel tank BUT....... should get it to run along pretty well. Should be at Mystic next year..... |
