I purchased a 2 1/2 hp Detroit Engine Works marine engine. Being new at the hobby, I did not realize until I got the engine home that the Griffin carb had been literally 'stuck' on the engine and did not belong there. What brands of engines did use the Griffin carb? What brand, type, and size of carb or mixing valve did Detroit Engine Works use on these engines? |

searcher, The Old Maine Engs that were made in late 1890's and early 1900's used mixing valves, This is from a 1913 Detroit hand book. As carburetors came into usage some co's offered both, this is same Detroit 1913 hand book, and says That this float feed carburetor is furnished with our engines! Could you post a Photo of your Griffin or e-mail to me and I'll post it here, I don't have info on these carbs. [email protected] |

I have a Griffin Model G which came with the 1908 Ford Model S car I am restoring. Can anybody give me advice on setting up the carb? Are any instructions available? Thanks. John Biggs |

Any of these carbs where the throttle lever overhangs the flange where the carb is bolted to the manifold is probably an accessory for a Model T. There were at least a dozen of these manufacturers who touted them as being more efficient or offering better performance over the Holley NH or Kingston L4. Both of these were single jet carbs with the L4 having a flap to vary the venturi area versus rpm. Some of the designs of these accessory carbs are quite clever, but they were probably no better than the stock carb. I have even seen some Schebler or Wheeler-Scheblers with separate idle and high speed circuits as well as provision to dump in more fuel under hard acceleration (a la throttle pump). Your Griffin is probably one of these with lo/hi speed circuits. Pretty straightforward, just make sure the float assembly is operational, all the passages are clear, open both needles ~1/2-3/4 turn and try it out. Once you get the engine running, you can play with the lo jet at idle and then the hi as you rev the engine. Basically it is similar in design to an 70's Briggs+Stratton lawnmower engine with lo-hi jets. Hope this helps. |
