Hey I need some wisdom,I was driving my 69'800 doing about 3or4mph in a field and it just died like I turned the key off,no sputter,cough,or backfire.I thought it was fuel but the pump is working perfect and I can see it spraying in the carb.I checked the spark in all cylinders and it looks good, nice and blue.I have had pertronix in it for a year with no problems,it has a new cap and rotor.I put a new key ignition in it,I can here and see the cylinoid open and close.I am running all original as far as I know a v8 304,holly carb,and vaccum advance dist.I had a friend crank the motor and I put a timming light on it and it was at 0 like it was supposed to be.so I have fuel and spark,but no idea what to try next.can anyone shed some light on this problem?
