Going through the entire car tightening/torquing every nut, bolt and screw...Checking tolerances on door, hood and rear deck latches...Balancing tires/wheels...Lubricating everything that moves...Locating and stopping various oil and fluid leaks...Tuning (spark plug gap, valve adjustment, timing, carb adj, etc.) after run-in...Clutch adjustment after run-in...Shifter adjustment...Brake adjustment/balance after run-in.
Some people view this as a pain, others as a part of the "joy of ownership" related to owing a primitive sports car...Depends on (1) Whether it bothers you to get your hands dirty, (2) When something breaks (See Vicki), and (3) Your tolerance for frustration/problem solving.
I have owned 2 air cooled four cylinder Porsches (1962 356-S90 and 1966 912) and find that once broken in, my Spyder requires no more "fiddling" than either of those cars.
Hope this helps.
