1st plug was removed and looked ok, cleaned and checked gap all good, tr
ied to remove no 3# cylinder plug and would not break loose and snapped it off flush i put heil coil in and check all marks and everything is all good but its not starting retarted and advanced dist it popped like it was gonna start but battery went dead and my customer is very persistaint and asks to many questions and had someone look at it wich offended me and they removed some parts and replaced them like i wouldnt notice the cap and rotor are bad , but it started before the plug broke with cap and rotor being bad what could be the issue
