Hi I have a Troy bilt lawn mower that was working amazing before one week No problems I left it to sit after cutting my grass as always I came back the following week for my weekly routine of cuttin the grass but this time there was no spark so I tried changing the plug and still no spark then I removed the egnition coil and saw there was a lot of grass on the ground cable so I cleaned that off now when I pull the rope it sometimes makes a loud poping noise I think it’s a back fire or something please help

Are the coil legs 1 business card away from the flywheel magnets?
Is the kill wire insulation cracked/torn and you are killing spark? Pull wire off and look for spark.
Other: sheared the flywheel key.

Thanks for your reply I appreciate it I actual eye balled the coil legs I can fit a recipe in between so I will definitely be readjusting that I think the kill wire is good but I don’t know what’s you mean by am I killing the spark and I don’t think the fly wheel key is sheared thanks for your reply I’ll let you know tommorow after I adjust the coil legs

Kill wire - if insulation is rubbed off, it could be making contact with metal (ground) and killing the spark. So, pull kill wire connector off the coil and then look for spark.

So you want me to remove the kill wire and check for spark?

Yes, pull wire off. Pull plug and ground side on metal engine part. Look for spark.
