all i can say is run it till it won,t start again and than check for spark and check for fuel...............pull the line at the carb and crank over to see if its pumping and if so take the plug out and lay against the engine and crank over to see if you have spark.......post findings, you,ll have to take a few tools with you a screwdriver and a socket and racthett for plug unless you have a spark tester............................
