Small Engines (Lawn Mowers, etc.)/lawnmower won t start


So my grandson decided to remove and throw away the choke springs on my briggs mower. After alot of searching i found the correct picture and rrplaced springs in the correct places and it wont start. I have fuel i have spark. This unit is a automatic fixed design and it seems that if it had a manyal choke style i woildnt have any issues. What if any adjustments do i need for the choke and or linkage to get her started so i can get back to mowjng?

There are no adjustment on the auto-choke models.

If you have a plastic cover on top of the engine that covers the auto-choke/carb remove the cover.  DO NOT remove the metal starter need in order to pull the starter cord.

Can you move the auto-choke arm back and fourth by hand?

One trick to see if the engine is being over-choked is to move the auto-choke open by hand and insert a drinking straw a screwdriver in the carb to hold the choke open while you pull the string and see if the engine starts.

Let me know if it starts when holding the auto-choke open.

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.
