Don,
You would not walk into the doctors and say "I feel the same as the other guy" and to some extent mowers are the same
So exactly what do see see, hear , smell & feel when you turn the key ?
How old is the engine ?
What is it on?
Does the engine crank & not star ?
Does it fire a couple of times but not carry on"
Dose it turn over ?
Silly little things happen like not having enough oil so once the engine has been running for a while and oil is splashed all over the engine the oil level in the sump drops just far enough for a slightly out of calibration oil switch to trip & kill the spark, particualry if the mower was parked slightly up hill. ( A real life call out cost the customer $ 60 to be told to add 4 oz of oil )
