Yes and it would be popping and farting out the carb. Rotor spinning under the cap? Rotor in place? Not in 180 degrees out(still should have spark)? I like using an actual plug with a ground wire attached to the threads of the plug. Good plug wires? Check them with an ohm meter? Swap out what you can one piece at a time with a good known unit. Or try swapping one piece at a time onto another vehicle (if available) in running condition.
