Small Engines (Lawn Mowers, etc.)/late 70's-early 80's 8hp Briggs mod.190412


guy said it just died one day. can't get it to run. fires when fully choked and gas comes out of the carb. new kit,new coil,new points,good spark,seems to be not enuf gas too the cylander. sprayed starting fluid on both sides of the crank with nothing. cleaned valve seats good with carb cleaner and soft brush. any ideas?

Bad float?  Compression?

A good rule of thumb for Briggs compression it to quickly rotate the flywheel backwards and see if the flywheel bounces or snaps back to the correct direction during the rotation.

What are the vavle gaps?  Is the flywheel key sheared?  What is the point gap?

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.
