    was working just fine yesterday then all of a sudden it started sputtering and then died. now it wont start at all. i cleaned the carb and still nothing. i've pulled the starter rope 20 times and it doesnt even act like it will start. what could possibly be wrong.

    the serial is 3503511571
    the model # is cv15t

    Are you getting spark from the plug ?

    If you are holding the body of the plug to a ground point on the engine while pulling the rope you should see a nice blue spark jumping across the gap.

    You didn't mention what type unit this engine is on but there should be a white wire from the engine to the unit harness. Dis-connect this white wire (kill switch wire) and check for spark again. If you now have spark there is a problem with one of the safety switches.

    If you still have no spark with this white wire dis-connected the ignition coil (Module) has taken a dump and needs replacing.

    Is that the only wires you see ? Is this unit electric start ?

    i see what youre talking about coming out of the engie. its then goes into a plug with 2 wires. how can i disconnect the white wire without messing up the plug?

    Just un-plug the whole connector then check spark again.

    You can check each safety switch by un-plugging them and using a multimeter set on ohms. Test lead on each leg on the switch, They should read open then closed when you activate them.
