starting woes

so i got a pertronix for my 53 super wasp. put it in buttoned it all up and cranked and cranked until it started for the first time last night. my friends hand slipped and choked it out and it died. i turned it off and there was a clunk sound. now the daytime i cant get it to start. i have spark at the spark plug wires to the block but no go. plugs keep fouling for some reason. help?
