hello hun
time it like they said leave belt off do not put your finger in the hole . use a thin screw driver you will breake your finger . plus u want to use no1 plug this swill be top dead center then face the dis rotor toward no. plug put the plug back in and then start it turn the dis on till smooths out . good luck to u hun do not put your finger in hole . also u have a pretty name and let me know how you make out pete
