Question about Briggs & Stratton Lawn-Boy Insight Series 21-Inch 190cc 650 Series Gas Powered Engine Variable Speed Self-Propelled Lawn Mower
Ran over somthing with lawn mower now it wont start, check flywheel key its ok
You're right to check the flywheel key - are you certain it's ok? Also our instinct is to tip the machine over to clear the obstruction, which can send oil to places it shouldn't be! Does the machine have compression? It's possible to break the con-rod if you hit something really solid. You can check the piston's still moving by taking out the spark plug and inserting something like a cable tie in the plug hole. As you turn the engine over you should be able to detect the piston moving up and down. The jolt could also have dislodged coke in the engine that could foul the spark plug. Try fitting a new one. Come back to me if none of these solutions work..
