Small Engines (Lawn Mowers, etc.)/snowblower running rich


hello,I have an older craftsman blower model C950-52677-8 I believe
it is a tecumseh 8hp,everything was running fine then midway through
clearing the wet snow on my driveway it started missing.I thought there must be a problem with the plug or wire,there is a black soot on the plug.I have since replaced the plug and fuel with no effect.
I was thinking of replacing the carb,is there anything else that would give it the same symptoms?

Black soot indicated a rich running condition as you mentioned.

Have you ever cleaned the carb?

Did you look on You Tube for carb cleaning videos???there are lots of videos on You Tube and clean the carb is not that difficult of a job but an air compressor really helps.

Do you have a basic tool kit?

DO NOT mess with the governor and let me know if you want to try cleaning the carb BEFORE you remove it.

You can try removing, draining and cleaning the carb bowl nut on the bottom of the carb...this is the high speed jet and is easy to clean as long as you can access the nut.

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.
