Does anybody have or know of a photo of this Sintz marine engine that includes the carburetor? I'm working on a comprehensive CAD model of this engine, but the engine I'm working from does not include the carb. Any help would be much appreciated.

Is The Engine in photos above your engine ?
This one and one in my collection are the only two that I know of, there may be more but their is no identification tags or castings so others may be unknowns !
Claude Sintz the oldest son of Clark Sintz came home from serving in the Spanish American war and started back into the marine engine business with this engine, it was designed early 1902-04
and Sintz mfgd and advertised them in 1905 and 1906, Trade name was "LEADER" oddly enough in 1907 his company was renamed Sintz-Wallin and they advertised a most magnificent opposed twin that also carried the trade name "LEADER".
This 1905 ad shows what your looking for although it isn't a carburetor, it is a fuel mixing valve ( no float bowl) after researching this for several yrs I believe that the valve was
designed and made by Claude Sintz, it is a unique design with a spring operated poppet valve for two port engines ! I am assuming by the design and size of the single mount flange on the manifold that the same valve was used as the ad shows only a larger one so that a single valve could feed two cylinders !
After looking closely at the engine photos above the cooling water pipes are cobbled up and not original routing, your (very cool depiction) shows the water inlet for the front cylinder just below the exhaust outlet ? Exhaust piping also cobbled up and not original design ?
These are photos of 1905-06 Leader, exhaust is original set up, the water pipes are cobbled as well but at least go in the proper places ??
Would like to know more about you project ?

In short, I work for a antique engine collector (among other things) near Louisville Ky. My boss would like 3D models of his favorite engines for documentation purposes and to possibly donate to a museum. We have also discussed creating a website to demonstrate how the old engines work and to show exploded images.
we realize that the engine we've obtained has a lot of aftermarket parts on it. Someone fixed a pulley to the crankshaft opposite the flywheel so I'm guessing that this was re-purposed. I'd love to get either a drawing or picture of one of these mixing valves if possible. Do you know where I might be able to find one? |

I have a single of this engine without the original mixer that runs well. Tagged as a Sintz-Wallin. 1 1/2 hp I believe. Jeff |

Jeff,Ernie
I appreciate these photos and the
one of the tag which I had never seen before!
Sintz-Wallin was successors to Claude Sintz Manufacturing Co. that originaly mfgrd these
headless two strokes, this eng tag confirms that
these engine were continued to be sold by the newly formed co., the Sintz-Wallin ads only show their
opposed twin engine that was used by U.S.Navy and so far I haven't found a catalog ?
Sintz-Wallin existed from 1907 to 1914
1907
Good Stuff Thanks again
