pulled the plug, and spark seems to be very weak.
Is there a common problem with this model that might be causing this? Anything in the elec system that is most likely to be failing? Any suggestions at all? I'm not much of a mechanic, so I'm unlikely to start tearing it apart with expectation of a solution unless I'm zeroed in on the likely culprit. I hate to have to take it in for service. A mechanic in the local shop told me there was either a spark or no spark; there is no such thing as "weak spark." That statement left me with little conficence in him. Am I wrong?
