85 phazer running on one cylinder

ive had this phazer for about a year now and i have sucessfully redone the entire fuel system last year, this year i re cleaned the carbs twice and changed the plugs. i took it out and it ran great beside the bog on launch. Today i went to start it up and it seemed to be running on one cylinder. i took the plug out and placed it on ground and there was no spark. but it was went. i changed it and it continued to run on one cylinder. i took it for a run around the house and when i went to check it it was colored black. so it must be firing i assume but why not all the time? i swapped the plug wires around the there was still nothing on that plug. can anyone think of what would cause this?

An inline detector will tell you if there is spark all the time.
Also, you might want to check compression.
