Palmer Moore claims to be the first mfg of open base two cycles. As far as I know, they are the only maker of open base two cycles. How would you get the mixture into the cylinders? They must have had a separate chamber to pressurize the mixture, that must account for the weird cylinder shape. |

These designs look like a precursor to the Caron engine which is a 2 cycle engine with a oil sump lubrication system for the main and connection rod bearings. In this way atleast, the oil and grease wasn't flung around the inside of the boat. even with the closed crank cases, though eventually oil and grease tend to coat the bilge of every boat ( with an older marine engine) I've ever seen.
Have you ever tried to step on a mix of bilge water and grease ( and not slip arse over teakettle?)

I have a 2HP--2cylinder Buffalo Gasolenemotor Co.---1899 engine & I need to know what the tappitt clearance is as well as the tension of the spring in the Lukenheimer mixing tube(carb)
Any other technical info on this engine would be greatly appreciated. This engine powers my 1894 motor-sailor! |

I don't have any technical info on this engine, can only offer a guess. I would set them at .015 to .020", I would be worried more about them being too tight than too loose. The Lunkenheimer on a four cycle only needs to stop fuel flow if the system is gravity fed, if the tank is lower than the mixer then the valve acts as a venturi. On a three port two cycle the valve has to close between strokes to act as a check, spring tension would be more critical. The valve should be easy to open by hand and snap shut when let go, you'll have to experiment with different springs if you think you have a problem, I don't think you'll see a big change. This sounds like a nice setup, would like to see pictures if possible. Do you have the serial # of your motor, I think Bob L. has #110, but he doesn't know the date on it. Is yours sparkplug or ignitor fired? |
