gizz wont start when it cold with starter but will somtimes will if I use the pull cord. and it like I dont have spark. it has gas anybody have this hapen to you or know what to look for its vary dusty up hear maybe dust got in somthing please help

 

Just a guess, but is your battery fully charged? I have an older model Yamaha that I don't use often, but if I don' t keep it fully charged, it will turn over but just will not start. I don't use it often enough to be a problem, so I just put a charger on before I am going to ride it and it starts right up. Old machines have a tendency to get that way as I had an old gas powered tractor that does the same thing, so I gave it to my brother who likes to "tinker".

Of course it might be those new tires you put on it...

 

I put a new battary in but it dont help . and before I could pull start it and now it wont start at all
