St lawrence started in 1910 with # 500 and wen to 1917 with about #1850. There was a new investor in 1917 and they jumped right ahead to the #5000 series in 1918. St Lawrence was involved in servicing shell production machines until 1919. Sales were slow after the war so your engine is probably 1921 or 1922 assuming 150 engines a year production. |

Thanks to Foxman & jb castagnos , Does not sound as though the st. lawrence was very popular. Is there any intrest in the brand? I would think it may have used a popit valve carb any one know? |

The St. Lawerence is a 3 port, any carb will work on it. My engine runs great from very slow idle to wide open, they were known as a dependable engine. |

FYI
Popular is relative. Ferro lasted about 10 years and produced probably 30,000 engines. Palmer lasted umpteen years and produced tens of thousands of engines. St. Lawrence built their first engine in 1905 and their last in 1965 or so so they lasted 60 years and prodcued about 3200 engines. Their basic single cylinder model (which you have) was produced mostly unchanged for those 60 years. I would guess that almost 1/3 to one half of the St. Lawrence engines built survive to this day, many in running condition. All engines were hand built in the St Lawrence machine shop on a 16 x 4 foor work bench. Lozier had a huge plant in 1905 and the pictures show hundreds of engines being worked on at any given time. Lots o' luck finding even one today. St Lawrence sales after 1919 were always slow but always steady. |

It was interesting to come across these postings...I happen to have two or three St. Lawrence engines in my shed. One is very old (gear water pump) and another other (in parts) has somewhat larger cylinders. They have been there many years and I am uncertain about their condition. I was interested in restoring them once but never found the time. |

I never considered selling these engines... I was quite facinated by them as a youngster (I had use of a friend's 22' St. Lawrence skiff and even a Dispro on occassion!)
But I certainly don't want to see these engines fall into ruin waiting for me to restore them. Let me think about it. |

OK...those St. Lawrence engines are, sadly, in rough (but restorable) condition. If there is anyone interested --capable; and ready to start, it may be possible to acquire them from me at modest cost. email me at ronb @ kos . net. |
