QUESTION: I have a Craftsman 3.5 hp edger model # 536796516 code 7278.  i was given the unit not running with the help of starting fluid and a good carb cleaning it will run for a few seconds then die.  I want to replace the carb, I know it is a tecumseh but cannot find what model engine or carb, i contacted sears but they will not divulge that info and will only sell a sear replacement part for $80. On Amazon I found a carb with good reviews but want to make sure it is for direct replacement of the current carb but again do not know a model number..

Can you provide any assistance please?

ANSWER: Did you use a flashlight and look on the engine starter housing for stamped engine model or a stick with the model number?

The engine model number should be a 143.xxxxx.

Let me know what the engine model number is.

You have a Tecumseh H30-35374S engine.

The carburetor part number is Tecumseh 632615.

Your carb maybe be a diaphragm style but the replacement float style will work on your engine.  I prefer the float style over the diaphragm style.

You may have to replace the air filter housing but that is an easy to do job and the parts are cheap.

The parts lists shows the engine may have been a snow blower engine but it should work fine with the float style carb and an air filter.

You may have to order Tecumseh 35797 along with the screws, o-ring, cover and air filter.The Ebay URL shows a picture to the air filter collar.  These are very popular and should be able to find all used parts at you local mower repair shop for less than $20.00.

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
