Sorry about that --  it was pretty stupid of me not to have provided that info.  Craftsman 917.377593.  6.75 hi-torque hp  Eager-1.  Not sure where to get engine code number and model number.


You have a Tecumseh engine.  Are you sure you have spark?  You can test by removing the spark plug and then connecting the spark plug to the spark plug wire.  Ground the tip of the spark plug to a metal engine part and pull the should see a spark jump the spark plug gap.

FYSA, here is a common carb part we sell for your engine, Tecumseh 730637A.

Let me know if you have spark before ordering or replacing any other parts.

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.
