I have a 3HP Lathrop, serial #16216, that I use every summer in my wooden boat, built in 1922, here in Twillingate, Newfoundland. The engine works flawlessly, but I wish to replace the original carberator with a newer schebler, but when I change it, the engine does not start. Do I need to install an airbox with the carb? Also does anyone know the manufacture date of the engine? I know it was built before 1922, as it was installed when the boat was built.  |

I have been gathering information to be able to Date the year of Mfgr of Lathrop engines, in this case having an original engine with serial number in a boat with a known mfg date is very helpful to my input data. Your serial number falls right into the sequence of numbers of Lathrop engines made between 1920-22 as you already knew, but so far thats as close as I can get it !
Very special Boat and motor, Thanks for the photos ! |

After looking at your photo again it looks like there is an older styled Gas mixer on your Lathrop, if you put on a float carburetor It will need to have an intake check valve installed between the carb and the intake port. This photo shows an original Lathrop valve !

Thanks for your info, Richard. The photo answered my question regarding the airbox. Sorry so long to respond. |
