Are these sensitive enough to detect the spark on a Briggs & Stratton 3.5hp lawnmower engine?

All spark plugs require a very high voltage, usually 15kv +. I would assume that even a small B&S engine requires the same.

Does the top unscrew to fit motorcycle spark plug caps (usually only fit the screw at the top of the spark plug)?

Regret no - no sign that the terminal tops unscrew. Stepehen Kiefer

Would these work on my positive earth classic car?

I assume it will, if is a primary DC +/- which operates the coil and will normally function either way round for Pos. or Neg. cars.
