Does anyone know what model carburetor this is? It is a Lauson brand that was bought out by Tecumseh. I bought this snowblower used and the seller told me, he thought the snowblower was a Jacobsen. It's a single stage (smaller) snowblower with 4 curved rubber paddles and the entire body is orange plastic.
The snowblower started coughing and finally died the other day and believe it's time for a carb rebuild and can't find a kit anywhere. Here is a picture. The numbers stamped on the side of the carb are; 544 8e31 (The 544 could also be 5zz, but pretty sure, it is 544) On the inside back of the carb, (where it attaches to the manifold) are the numbers; 1091-162.
It looks like A lauson carburetor. And you should be able to get a kit for it at c&c Distributor.www.ccdist.com OR1-574-233-6667 I have one. I am working on now for someone, that looks just like the one you have shown in your picture.
It's from a sears craftsman snowthrower. A lauson carburator
I rebuild several of the 85-98cc Tecumseh motors for the racing community. I have found the biggest difference is the throttle plate hole location and the jetting so any of the tilson-lauson carbs will work if your up to cutting off the throttle plate and silver soldering it to a different one I have had to do this a lot.it sounds to me you have a 1500 or 1600 series Tecumseh and your right there about 3.5-5 hp depending on the porting.
Also I don't know if it will help because of carb location but I have also put several 5hp Briggs carbs on them but they are float style and have to not exceed a 15 degree slant or they will flood out your engine case. I hope some of my rambling may have helped and I am sorry for my English is not so great. Have a wonderful day.
