i replaced the coil this mornin with a coil i had laying around and it storted up but i found on the coil that it was burnt with a small pin hole in it and if you move the coil around it would start up will this make it start cutting out when it gets hot and does the coil have to be grounded when you try to start it it wont start again right now but going after a plug wire set today and bolt this other coil down thanks for your help
