I'm surprised no one has warned the OP against trying to start/run the engine with the spark plug loose. Eventually he's going to damage the threads in the head and then he'll have bigger problems.
I have to agree with BBB. It sounds to me like he doesn't understand the proper use of the clutch and/or his clutch cable is way loose. I can't see spark plug interference if he's actually had the engine start and run. That doesn't make sense to me.
