Maintenance on the Lawn-Boy Dura-Force engine 

Great video. Thank you sir

A trick I leaned a long time ago was to use a lighter to burn off carbon on the spark plug. I never had a lighter so i just used a blow torch. Seemed to work fine and the oem sparkplug still works great

Thanks for the video, but FYI it's 0.030 inches, AKA 30 thousandths.

I have the exact same mower

Thanks, the exhaust is probably my issue, runs splashy, misfires and blows a lot of smoke when i shake the mower when it is running, my early lawnboys had the muffler under the deck,

Thanks, buddy. Good vid.

Thanks for the help.

please do video on exactly how to scrape carbon off. no maintenance on self propell?
