It still could be a fuel issue. Remember I have to pump the gas pedal a lot after it has been sitting for some time (weeks or months). It cranks over fine, just won't start up.
Then after it has started once, I can leave it for a few days, and it starts right up. If it sits longer (maybe a month or more) it won't start again. These symptoms seem more like a lack of fuel issue. It has been so long (years) since I last worked on this, so I don't remember what all I checked way back.
I need to remove the engine cover and air cleaner and check for gas when the pedal is pressed. If there is no gas, then maybe there is a leak in the gas line, or the fuel pump is not working, or there is a plugged up fuel filter (although I remember looking for one before and couldn't find one).
