pkhammer Posted June 16 Share Posted June 16 Picked this up at a flea market yesterday. Solid brass carburetor with no markings. 5 1/4" from flange to flange. Measures 1" NPT on both ends. Was is a box with a couple model T carbs but I don't think this is model T even though the overall size is similar. Link to comment Share on other sites More sharing options...
dustycrusty Posted June 16 Share Posted June 16 All brass, a "tickler" instead of a choke and a hand throttle denotes something you would be standing over or sitting next to= a stationary farm or industrial engine or maybe an inboard marine engine in a small "Motor Launch"? 2 1 Link to comment Share on other sites More sharing options...
mechanician Posted June 16 Share Posted June 16 Looks like a Holley marine carburetor, or perhaps a copy of one since it presumably isn't marked. They were often stamped or tagged near the tickler. The tickler is found on very early carburetors of all uses, including automotive, the throttle handle on the other hand...ahoy. 2 Link to comment Share on other sites More sharing options...
Layden B Posted June 16 Share Posted June 16 Threaded air intake is also a marine feature. The intake would have had a flame arrester Intended to keep a backfire from lighting off a bilge fire. You might think that it would be best to pipe in outside air but the engine also provided ventilation much needed in the confined space. 3 Link to comment Share on other sites More sharing options...

dustycrusty Posted June 17 Share Posted June 17 21 hours ago, Layden B said: "Threaded air intake is also a marine feature." Thats true, but not exclusively. Land-based Novo stationary engines also used a (somewhat) similar carburettor, screwed directly into the block. If this particular carb also screwed into a intake, head, or block, then we are looking at it backwards. That would make the "throttle" a choke lever and the fuel flow would be unregulated through the carburetor once it got past that mixing screw. That in turn means that the engine speed would have to be controlled by another means, most likely by a "Hit -n- Miss", make & break ignition system or a mechanically disabled exhaust valve that is held open until the engine speed drops below a set RPM. Both of these methods of governance are dependent on flyweights and centrifugal force rather than limiting fuel intake via a throttle plate or a butterfly valve and were more suited to stationary applications. Perhaps a query over on Smokstak would yield a definitive answer? 2 Link to comment Share on other sites More sharing options...
Layden B Posted June 17 Share Posted June 17 dustycrusty Many early carbs for all applications had pipe threads to mount to the engine as in your picture of a stationary. My comment was about the threaded air intake where the air enters the carb. Note that the carb we are discussing has threaded connection on BOTH ends! 2 Link to comment Share on other sites More sharing options...
