Question
Hi, this mower gets used once or twice a year. 8-9mths since last used.
Fuel looks OK possible old. Spark present at plug.
turns over but seems to kick back after each cycle.
Mechanic last year said the cams need regular adjustment.

Would like to know how to check these & adjust if required.

sorry don't presently have model No. handy.

regards
Phil

Answer
I need the engine model information to see if you engine needs regular cam adjustments.  

Remove the spark plug and see if the kick back stops.  Look to see if any fluid squirts out the spark plug hole.

Fuel, small quantities like mower gas containers in the US, starts to go bad in about 30 days.  After 8-9 months I have had fuel that would not burn even when lighting with a butane lighter.

Is the oil level correct?  Does the oil smell like fuel?

Experience

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.
