What engine model number? Briggs single cylinder? How long before it will restart/ If you check for spark by removeing spark plug wire and attaching a spare spark plug, and ground it, do you have spark?

Expert:  Curtis B. replied 4 months ago.

Briggs 310000 series is a single cylinder engine. If it does have spark when it quits, then we have to assume it is a fuel problem. with it having to cool off, the only part that us fuel related, is the fuel solenoid in the base of the carburetor. Solenoid has to have 12 volts to stay open, and should have an audible click when key is turned on and off. Learn what the click sounds like when engine is cold, by turning key on nd off. Then when engine quits, turn key on and off, and listen for the click. No click, no fuel!
