Ok, replaced pickup coil today. took it out for a spin and afer about 15 minutes of driving it died. I was stopped on the street talking to a neighbor who restores cars telling him what i had just done when it was like someone turned off the key. We popped the hood looked around there was fuel in the filter. I restarted and it idled for a while and died again. As soon as it did I took the gas gap, which is new also, off and there was no sound from it. I restared it drove around for a while came back to the neighbors pulled up and it died again. Now i'm starting to think it might be a bad coil. The langdon kit comes with the square coil but i got the optioal round coil. Should i have gotten the square coil in the first place. Those of you running the langdon setup what coil did you go with.
