Hello everyone. I just picked up my first St Lawrance 3-4 hp single cylinder marine motor. It�s missing the carb. From what I have read there are different NPT thread size for carb to manifold. Did they all use the same schebler D carb?  |

My 3 hp circa 1925 has a Schebler Model D. Standard pipe thread between the carb and the crankcase.
Cheers! |

I think the head on your engine is on backwards.
The priming cup should be at the front, 180 degrees from where it is now.
It matters how the head is put on - there are water passages that make the difference

Most St. L engines have a 1 inch intake thread.
Does your Atlantic engine have igniter or spark plug. Bruce |
